The legendary TM Racing 125cc and 144cc 2-stroke engines are synonymous with performance, constructed from some of the best materials for maintaining performance and reliability these already world class engines and their ancillary components receive the following upgrades for 2017 with their performance as a production engines already being regarded as outstanding. For 2017 the 125cc and 144cc engines are treated to a new main-shaft in the gearbox with a slightly differing fixed gear design and new treatment for even greater friction reduction. The most notable change to the engines comes in the form of a new cylinder port / port timing arrangement with a new nicasil cylinder wall coating, all designed to maximise the performance of the engine alongside the TMEES electronically controlled exhaust valve, which also features a revised electronic control program. This new arrangement in the cylinder gives better response with a gain in power/torque at the lower range whilst maintaining the mid / top end performance of the engine, the TMEES system electronics have been profiled to work seamlessly with the engine electronics to ensure power, torque and responsiveness is at its best at all times for each given discipline.

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 reliability and more consistent 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.

'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' units with multi sprung pressure plates.

ENDURO / ROAD EQUIPMENT: All Enduro and ‘Road’ designated variants of the TM racing model range come with full 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.
