After another season of great results, the small Pesarese manufacturer has once again taken their products to the top of the world stage, against the much larger manufacturers and their limitless resources. TM Racing have again taken world championship titles in two separate disciplines and class structures, the E1 Class title at the World Enduro Championship with the 250Fi ENes machine for its second consecutive year, and, the S1 World Supermoto Championship title with the dominant 450Fi SMX, a multiple time world championship winning machine. TM Racing have taken their handcrafted, high specification, high quality and high performance ‘customer’ machines to the top of the most competitive World Championships, whilst also adding a multitude of national and domestic results to their tally throughout the TM Racing global network, with both 2-stroke and 4-stroke machines in various disciplines.
So, what can we expect for the 2017 model range…….
TM Racing's exceptional quality remains as always, built to perform at a level in standard trim beyond what is the conventional. Greater performance throughout, not just in power, but in delivery and rideability, alongside improved handling in all terrains with new chassis geometry changes' and suspension units. Combined with real 'wet' weight reductions with better centralised mass, making some of the lightest 'ready to ride' machines in their class. True performers, race bikes built to race from the offset, what we all expect from a racing machine.
For 2016 the whole TM Racing range was given numerous beneficial updates in both the chassis areas and throughout the 2-stroke and 4-stroke engine range with a mass of changes and some unique technical innovations once again, and as is now customary, all done with the TM Racing philosophy of ‘’we build it how we want it to be built’’, not working to a ‘budget’ plan, a philosophy that leaves many dumbfounded as to how TM can produce what they do, in the volume they do, for the end consumer price. For 2017 the TM Racing range once again sees some beneficial changes being adopted throughout the models, these include some chassis’ changes and some smaller engine and technical changes designed to further enhance an already great package of machines for every discipline. TM have not redesigned for necessity and tried to reinvent an already round wheel, just in the quest for additional promotional sales literature or to distract from reduced production costs. With a multitude of exceptional materials, quality machining and treated parts on the inside, that are seldom seen, matched to a huge number of machined aluminium and high quality parts on the outside, TM Racing motorcycles are constructed to a near ‘factory’ machine specification list, albeit designed for the retail consumer. TM Racing ‘factory’ bikes have more in common with their production counterparts than would ever be believed, the TM Racing ‘factory’ machines run the same componentry as the bikes they produce for their customers with settings and new parts being applied for the purpose of testing, developing and improving their models in the materials they use for actual production. A great testament to the TM Racing philosophy and the build quality, performance and strength of their stock parts, stock parts that others have to sacrifice to achieve their goals. In short, TM Racing ‘race’ their machines at the very top of our sport to allow them to design, build, test and ultimately, produce bikes for 'you' that are capable of competing at the highest levels.
The larger capacity 2-stroke and 4-stroke machines have had some incredible and innovative changes applied to them in this current model generation guise, the largest and most notable, being the new air intake systems and the ‘reverse’ fuel tank on the Fi models, all of which again feature on the 2017 model ranges with some new addtions to the chassis constructions to reduce overall weight whilst maximising strength. This revolutionary intake system on the 2-stroke chassis, which features on all model variants of machines 125cc and above, not only allows the engine to breath cleaner and fresher air inducted from around the fuel tank area, but also helps to reduce air filter particulate contamination by controlling the intake of air from a ‘cleaner’ source. The ‘Fresh Air’ system allows for an increase in the engine performance by creating a better flow of ‘clean’ air into the engine, creating greater response and more power for a greater duration. With a large volume air filter being fitted to maximise the systems potential, the immediate performance gain is also sustained for a much greater period of time, even in the harshest conditions, conditions where a normal filtration system would have begun to become less efficient as a filter with a smaller surface area, breathing in a dirtier environment, becomes saturated with particulates at a faster rate. A contaminated and ‘clogged’ filter also increases the chances of particulates by-passing the filter and entering the engine, with the TM Racing ‘Fresh Air’ system this ‘risk’ is reduced and high performance is maintained. For 2017 the ‘Fresh-Air’ system remains and includes and optional update in the form of a new 12L fuel tank for the 2-stroke machines, ideally suited to the Enduro range, that gives a larger range for the hardest Endurance events but does reduce the intake size of the 'Fresh Air' system. The introduction of the ‘Fresh-Air’ system also brings another added advantage in the form of a lower centre of gravity, with the fuel tank now positioned slightly further into the chassis around the engines cylinder, this, combined with the latest type frame geometry and new chassis assemblies for the 2017 model range, further reduces the overall weight of the machines and increases their agility on track. The suspension has been designed to work harmoniously with new fork and shock internal settings and a new shock sealing system with new friction reducing seals. These changes turn, what was already one of the best handling bikes in many tests globally in 2016, into one that for 2017 will yet further enhance these already great characteristics.
On the 4-stroke machines, starting with the 250Fi and continuing through to the mighty 450Fi and 530Fi capacity models, all variants of the 4-stroke model ranges will continue to adopt the new ‘reverse’ chassis layout which is proving to be a world beater in both off-road and Supermotard variants. The latest generation chassis layout for the 4-stroke machines will see some minor modifications for 2017 in the form of some altered fittings for the componentry along with some chassis changes noted later. The ‘reverse’ layout, seeing the repositioning of the induction area for the engine and the fuel tank, saw TM Racing totally redesign many of the existing chassis and ancillary parts. With the fuel tank now situated under the seat and the intake system air filter box now sat above the engine, combined with countless chassis and suspension changes, this new system witnessed a huge transformation to the complete range of 4-stroke model machines. With the centre of gravity lowered further into the chassis, noting that each capacity model has its own main chassis unique to that capacity engine, and with new suspension componentry working harmoniously alongside, TM Racing created a line of much more nimble and agile machines. In 2017 we also have the addition of a new chassis assembly constructed with elements that have been redesigned to reduce overall weight whilst maintaining maximum strength. Better handling characteristics, stability, turning and weight losses are gained throughout the range, as we can witness with new development models making their way into the TM Racing ‘factory’ race programs and the results they have achieved this year. TM Racing have once again won the World Supermotard S1 championship, taken a second consecutive E1 World Enduro Championship, and more recently in the latest 'prototype' model guise in the World MX Championship, gained massive publicity with the revised 250Fi that has been turning heads throughout the 2016 season.
85 MX Junior - Small Wheel 14" / 17" - Big Wheel 16" / 19".
The 85cc machine will receive only minimalist updates for 2017 designed to further enhance an already incredible package, with a growing reputation of being one of the best ‘out-of-the-box’ 85cc machines on the market, the TM 85 MX machine has an ever increasing track record of excellent results and great reliability. With a chassis that not only gives superb riding characteristics but is also one of, if not the, lightest on the track in real world terms, matched to an engine that has a great spread of usable, class leading power. The smallest machine of the TM Racing brand range is constructed with not only performance in mind but also durability and is well received by amateur and professional alike in its characteristics.
The aluminium chassis, a first for a ‘Junior’ model, not only looks incredible but also delivers the lap times when matched to the ‘factory’ type fork and shock absorber arrangement, the suspension will have new internal settings implemented for the 2017 models to further improve this already agile machine. The new settings have created an even greater response to terrain changes with improved tracking and rear wheel traction, this in combination with the confidence inspiring ‘over-sized’ braking system that works, and keeps working, in the harshest conditions, gives a great chassis package of tried and tested components. Built to perform and keep performing whilst maintaining lightweight and retaining ‘upmarket’ componentry and strength throughout, the TM 85 MX is an incredible machine.
The 85cc watercooled, powervalve type engine features a billet crankshaft, a machined and treated con-rod, hand finished crankcases that feature a water jacket around the crankshaft area for reducing crank temperatures, a V-force reed block, hand finished cylinders, an oversize gearbox and clutch arrangement for superb durability and ultra-reliable clutch performance, die-cast clutch casing and ancillary covers for a smooth look, lighter weight and superb strength, a Kokusan ignition system and Scalvini exhaust system, all fed by a Keihin 28mm carburettor with an oversize intake bell mouth, breathing through a large volume Twin-Air air filter. For 2017, the already outstanding, 85cc engine will receive new crankseals designed to ensure increased seal durability whilst reducing frictional losses, the cylinder receives a new port / port timing arrangement to maximise performance throughout the rpm range and a new nicasil coating to the cylinder walls, combined with a small change to the powervalve system to once again give a better overall power delivery. Chassis components include, billet triple clamps, billet hubs laced to excel rims, billet rear brake lever, oversize brake discs with oversize callipers, braided brake and clutch lines, hydraulic clutch, Formula 39 Fork, Extreme Tech shock absorber, TM even felt the need to include a built in hole-shot device, the specification is endless. For 2017 the aesthetical look of the machine will remain the same with its already modern design replicating that of its big brethren, albeit for a new decal scheme incorporating some brighter colour accents giving a more striking visual appearance. A machine built with purpose, using some of the best components and materials available, designed to perform and keep performing without the need to invest heavily in the after-market, an excellent package of high performance, superb handling characteristics, light weight and excellent reliability for the youth sector.
Please Note: There is a new optional 12L fuel tank (opaque) that is available to be specified at the time of build. A great addition for the XC / Endurance rider looking to increase the range of their machine. Available for all Adult 2-Stroke models.
CHASSIS: The high end specification of all TM Racing machines is well versed and for 2017 this is no exception, once again the specification list for a production machine is vast and features numerous high quality components, many revised for the 2017 model ranges. All full size models will once again be constructed using an aluminium chassis and sub-frame, with each engine capacity variant having a chassis unique to that engine displacement. This ‘tailoring’ of the chassis to engine allows TM Racing to design and build each machine for minimal weight, compactness and better handling characteristics with mass centralisation specific to each model whether 2-stroke or 4-stroke. For 2017 we have a new chassis assembly constructed using redesigned elements that reduce overall chassis weight whilst maintaining maximum strength, all matched to new suspension settings specific to each model, 125 / 144 / 250 / 300cc 2-stroke machines each feature their own unique suspension settings for all disciplines. On all models, the now standard fitment KYB 48mm twin chamber forks (50mm DLC coated Marzocchi on 2017 SMX models), have been revised to give an improved response to the damping for faster changes to the terrain, all still controlled by the more favourable spring and oil set-up which is still proving to give greater reliabilty and more consisten performance. The TM Racing shock absorber, made in house by the TM racing technicians, also receives changes to its internal settings for all 2-stroke and 4-stroke models with a new 'sealing' system to reduce the frictional losses and increase shock performance, this combined with the recently updated swing-arm length, linkage components and larger rear spindle diameter to limit flex, allows for a more progressive feel giving improved track stability and maximising traction at all times. The new geometry and revised suspension components work together to achieve improved handling characteristics on a multitude of surfaces, allowing for greater stability in all conditions, increasing traction and inspiring greater confidence to reduce lap-times. The aesthetical look of the machines body panels will remain the same. The current appearance of the latest generation model range is still one of the most striking to date, a mix of angles and curves that blend seamlessly into each other from front to rear. Beautiful, yet aggressive in it’s shaping, the body panels will however feature a new decal scheme for 2017 incorporating some brighter colour accents giving a more striking visual appearance.
SMR / SMM Model Variants: All road designed models will feature the Marzocchi 50mm fork with a billet triple clamp arrangement, new for 2017, working alongside a Sachs shock absorber. This suspension componentry has been selected for road models where comfort and control on the roads requires a different set of parameters, these ‘softer’ units allow for a smoother progression in the suspension travel over the larger sized units fitted to the competition range, where more of the available suspension ‘stroke’ is utilised and therefore requires a firmer setting. Designed to work on the road, this componentry guarantees the best handling and comfort in all road conditions.
'FRESH AIR SYSTEM': The intake systems on all TM Racing adult 2-Stroke models feature the ‘Fresh Air’ intake systems allowing for the engine air filtration system to breathe cleaner air, this system reduces particulate contamination of the air filter maximising power for longer duration. On the 2-stroke machines the air in channelled from the intake vents, on the top of the fuel tank, to the airbox which houses a large volume air filter. On the 2017 model 2-strokes the efficiency of this system has been further enhanced by increasing the size of the intake channel on the fuel tank to allow an even greater volume of cleaner air into the airbox. The introduction of the ‘Fresh-Air’ system also brought another added advantage in the form of a lower centre of gravity, with the fuel tank now positioned slightly further into the chassis around the engines cylinder, this ‘weight’ shift, combined with the latest frame geometry, suspension linkage changes and revised shock absorber length, all work harmoniously with new fork and shock valving and internal settings, to turn an already nimble chassis into one that was rated one of the best handling bikes in many tests globally. The 4-Stroke machines also continue with recently adopted ‘reverse’ layout, which sees the fuel tank moved under the seat area whilst the engine intake and filtration system is now positioned above the engine. This allows the 4-Stroke engine to breathe cleaner air with a much more direct air feed into the Fi throttle body, filter contamination is decreased whilst engine performance and response is maximised. This chassis layout witnessed a huge transformation to the complete range of 4-stroke model machines, with the centre of gravity lowered further into the chassis, noting that each capacity model has its own main chassis unique to that capacity engine, and with new suspension componentry working harmoniously alongside, TM Racing created a line of much more nimble and agile machines. Better handling characteristics, stability, turning and weight losses were seen throughout the range as well as gains in engine performance.
WHEELS: The CNC machined billet aluminium hubs, laced to anodized Excel rims, now feature a new spoke arrangement with a ‘tapering’ design profile in a new stronger material, a material treated to increase corrosion resistance, larger spoke nipples now feature on the front wheel also for added strength. The new wheel arrangement allows for an increase in the strength and durability of the wheel components whilst reducing the un-sprung weight by a small margin. The CNC machined hubs, featuring external dust seals encircling CNC machined wheels spacers to further protect the wheel bearings, are mounted to the suspension components via large diameter hollow spindles. The larger diameter spindles, machined through their centres to lower weight, allow for a more rigid fixing off the wheel reducing the flex and allowing the suspension to work more effectively.
BRAKES: The braking systems of the TM racing model range has also received some new componentry for 2017 in the form of some new caliper options for the SMX range. The rest of the model range continues to feature high quality oversize wave discs working with TM Racing's 'mix' of componentry. Nissin master cylinders, joined with lined and braided high quality racing brake lines, operate a mix of Brembo twin-piston and Nissin single piston calipers. This tried and tested collaboration of parts that is regarded as one of the best braking systems in many tests and by racers alike. This braking system keeps working in the harshest conditions with the quality lined and braided hoses, designed to limit hose expansion under extreme loading, ensure maximum braking effort is transmitted to the calipers, giving great efficiency and inspiring confidence at all times. The rear brake system is actuated by a twin bearing pivot mounted, billet machined aluminium foot lever with a replaceable tip.
TRIPLE CLAMPS: The triple clamps fitted to TM Racing motorcycles competition range are CNC machined from block aluminium and each clamp is a work of art, the clamps intricate machining, most of which can only be seen from the underside, gives a structure designed to be supremely strong whilst keeping weight to minimum. The triple clamps also come with an optional ‘damped’ bar mounting system that, through the use of a tapering rubber cone arrangement, allow vibrations that can be transmitted through to the handlebar area to be reduced, whilst also allowing some ‘give’ to the bars in the event of a fall reducing the chances of more severe damage occurring to the handlebars and the components adorning them. The handle bars are secured, via the optional ‘damped’ bar mounting system, by billet machined bar clamps, with the top bar clamps featuring machined TM logo’s on their upper face.
CLUTCH ACTUATION: All TM Racing machines come fitted with a Hydraulic actuated clutch as standard, the master cylinder, made by Brembo, transmits fluid via a lined and braided hydraulic line to TM Racing’s own ‘slave’ cylinders. With separate slave cylinders for the 85/125/144 engines, the 250/300 engine, the 250Fi/300Fi engines and the 450Fi and 530Fi engines, each unit designed to fit and perform for each model giving a balanced clutch feel between all engine size variants, With both single and dual seal pistons in the slave cylinders depending on model application. The Brembo master cylinder, working with the braided hose that limits hose expansion under extreme load, gives great feel and precise clutch control with great durability when combined with TM Racings ‘cush-drive’ clutch baskets, which on the 250cc/300c and Fi variants are coated with a hard wearing, friction reduction coating. All clutches are multiple disc 'wet' untis with multi sprung pressure plates.
ENDURO / ROAD EQUIPMENT: All Enduro and ‘Road’ designated variants of the TM racing model range come with EU homologation and conformity certification. These models features a full, self-generating lighting system (which can operate also from the battery system on Electric Start models) powered by the crankshaft mounted electrical generator. This system includes a complete side, dipped and main beam headlight assembly, taillight and rear brake light - operated by both front and rear brake actuation cylinders – with rear number plate illumination, a turn signal system consisting of 4 flasher units and also a horn. All of these functions are controlled via a handlebar mounted multi-switch that also includes an ‘engine stop’ button, on Fi ES models a ‘choke’ lever also features on the multi-switch. Working alongside the lighting part of the system is an illuminated digital speedometer with ‘trip’ functionality, this speedometer unit registers the vehicles given speed via a sensor located on the rear wheel of the motorcycle.
ELECTRIC STARTING: The ES abbreviation in any motorcycles descriptive from the TM racing range denotes that the machine has ‘Electric Start’. The TM Racing Electric start system is powered by a new, lightweight, Lithium Ion battery that is recharged during engine running by the electrical system. Electric start can be found on all Fi Enduro models and Road models but is also available as an option on Fi MX and SMX variants.
The already world class performing TM Racing range of engines and engine ancillary components each receive some updates for the 2017 model range. These high-spec, high performing engines, are designated to each discipline, whether MX, EN, Road or Supermotard, and each feature their own unique variation on internal and external componentry and settings to perform at their best in their destined environment.

With the new gear position sensitive ignition working alongside the TMEES exhaust valve control system, featuring a new pulley arrangment and revised electronic control programming, and, the optional ‘handlebar mounted’ twin ignition map switch, the power delivery for each of the 250cc and 300cc cannot only be tailored by the rider on track, but the system also changes itself depending on gear selection and valve position ensuring the best power delivery and traction at all times. A system that is proving to be great for the hole-shot and those slippery rock sections alike, depending on machine and discipline of course, allowing the engine to give the rider the required power and torque at the required time, giving the best in traction in all conditions. Constructed from some of the best materials for maintaining performance and reliability these already world class engines that produce incredible, yet usable and controlled power and torque combined with quality ancillary components. Once again, the performance qualities and reliability of these production engines is already regarded as outstanding and for 2017 the following changes will apply.
The main focus of both the 250cc and 300cc engine variants for 2017 is the power delivery and maximising performance with unparalleled control of its delivery at all times, in all conditions. This latest generation of big 2-stroke engine performance has been achieved with a new cylinder port / port timing arrangement, a new nicisil cylinder wall coating and a new exhaust pipe, all designed to work seamlessly alongside the TMEES electronically controlled exhaust valve.

The TM Racing range of 4-stroke engines has become legendary for exceptional power delivery and outright performance and durability. The ability of these engines to perform has become renowned worldwide and for a ‘production’ engine the internal components and materials used are unmatched, many of these components and materials being of a level of quality that would only usually adorn the best of the ‘factory’ engine machinery. With an ever growing list of results globally, in many disciplines, the 4-stroke range of TM Racing engines has spread to accommodate not only the off-road sector, but now feature in other motorsports. We have witnessed the 450cc engine being adapted for the karting sector where its unique lubrication system, working a twin rotor ‘recovery and distribution’ pump with a lower cavity oil chamber for containment that feeds pumped oil to every part of the engine, has allowed this engine to work with the huge cornering g-forces that karts can create where others struggle to lubricate themselves as the oil swells to one side of the engine. The basis of the 250Fi engine has also been adapted and now sees itself being currently developed in TM Racing’s Moto GP program in the competitive Moto 3 class, this revised engine has already taken some good results during test races this season. TM Racing’s 4-stroke motorcycle range has also been a great success over the past seasons, with the 450Fi SMX machine now having taken multiple Supermotard World Championship titles, it currently leads the way in the 2016 S1 championship standings also, and has become regarded as the bike to be riding in Supermotard to get results. A purpose designed Supermotard bike that can be bought as a package, ready to thrive in this discipline where others are generally adapted machines created from other models. The 450Fi Enduro model was also recently adopted and developed to form the TM Racing Rallye bike, the 450 DKR / Rallye, a machine that has taken two consecutive world championship victories in its class, a great testament to performance and durability in the harshest conditions. The 250Fi variants are also currently setting the world stage alight where the 250Fi ENes machine (in production spec engine format) is leading the ultra-competitive, and manufacturer machine dominated, E1 World Enduro Championship class once again in 2016 after taking the titel in 2015, a great showing for the TM brand.
For 2017 the 4-stroke range features some small but dramatically enhancing engine changes, the biggest 'change' is the addition of a new 300cc 4-stroke engine based around the current 250Fi unit. Changes to the 2017 model range engines include new piston designs for all capacites, the already favoured box-bridge pistons have been redesigned to further increase strength whilst not adding any excess mass, these new pistons will work with a new nicasil cylinder coating that features on all models. A new clutch plate arrangement has also been implemented, increasing clutch durabilty under the harshest conditions and maximising clutch 'hook-up'. These already class leading engines are once again taking it to the top of the world stage in various disciplines proven their competitiveness and reliability at the highest levels.The new intake system, that sees the air-filter breathing cleaner air now it has been positioned above the engine where the fuel tank once resided and allows for a massive change in the balance and feel created by this redistribution of weight, has been a focus of the TM Racing technicians for the 2017 model range. The 2017 model range 4-stroke chassis' are also new for this model year and have been constructed using elements redesigned to reduce overall weight whilst maintaining maximum strength. Working with this new induction system on the latest generation of TM 4-stroke motorcycles, TM have also created new exhaust systems, these new exhausts have been designed to maximise the overall performance of the engines when combined with other changes that TM have applied internally and to the electronics. The new exhaust has been integrated with TM Racing’s engines and fuel-injection system to once again give increases throughout the range, maximising the power and torque available at any given rpm and giving a sharper response to throttle input, all whilst complying to the latest noise regulations. Especially when on the 450cc variants we have the adoption of a gear position sensor that works with the ECU to maximise traction in any gear at any given rpm, allowing the ECU to make changes to the Fuel Injection system to balance power, against available grip, giving the user the best power output for the conditions.
