After the numerous engine changes for the 2013 and 2014 models which included a new piston design, new reed valve position on the crankcases, new main bearings supporting the new billet machined crankshaft, changes to the cylinder and head, a new twin-ring piston design, a revised TMEES system, new CDi programming and carburetion settings, new intake system with a new filter cage, air boot and carb manifold, new gearbox roller mechanism for more precise shifting and a new exhaust with a HGS silencer. TM have continued to push development further and the 2015 model has recieved yet more changes to enhance performance and longevity, this includes a new crankshaft and con-rod arrangement, revised port timing to match the new re-worked cylinder, new main bearings and hi-tech seals, a complete new exhaust system, and a new TMEES pulley and cable arrangement has been designed and fitted to again boost performance and reliability of the TMEES system.
Chassis changes include modified geometry featuring a new rear shock length (8mm) matched to a new linkage for better progression and traction in all conditions with revised suspension settings, a new rear wheel spindle diameter with an increase of 2.5mm for added strength and less deflection of the swing-arm and a new plastics design in a fresh and aggressive style. This new plastic arrangement, also featuring a new seat and fuel tank incorporates a 'fresh air flow system' which channels cool air via a control channel to the airbox to maximise cold air feed for higher power output. This new look is finished with a fresh new graphic look in an Italian theme.
Other features include, a TM Racing 'Factory' rear shock absorber, KYB 48mm forks, billet machined aluminium hubs laced to anodised Excel rims, Billet machined aluminium triple clamps with damped handlebar mountings, oversize taper handlebar, oversize 'wave' braking discs, HGS exhaust system, V-Force reed valve system, billet machined connecting rod and a switchable twin map ignition system.
