Product Description


During 2014 the mighty 450cc engine has once again proven to be a world beater in many disciplines and for latest generation the philosophy was simple, small changes to the engine, larger changes to the chassis. For 2015 the 450cc engine receives ancillary chnages in the form of a new inlet ducting system, a new throttle body and air funnel into the venturi to improve air feed for power maximisation, a new exhaust system allowing for greater performance and smoother power delivery all matched to revised ECU settings, this is linked to a gearbox position sensor connected to the ECU to maximise performance and power delivery for any given gear ratio by altering the fuelling and timing of the fuel injection system. The already immensely powerful and torque laden engine required little in the way of performance increases and simple alterations have just improved its responsiveness at lower rpm's and facilitated easier starting on the conventional kickstart variants. The 2015 model engine continues to adopt the engine changes which graced the 2014 models and these included a revised connecting-rod matched to a new 'box bridged' piston with a DLC coated gudgeon pin, revised fuelling and mapping via the ECU working with revised camshaft durations, a new wiring harness, revised gearbox selector forks and selector barrel and a new clutch basket with a friction reducing coating combined with new fibre plates.
Chassis changes include new chassis geometry with modified front fork rake for increase turn-in, stability and all round 'lighter' handling characteristics a longer swing-arm for better bike balance and weight distribution, a new rear shock length (8mm) and revised linkage for better progression and traction in all conditions working with revised suspension settings. The big change in the chassis department is the adoption of the new component layout designed to optimise weight balance, handling and engine performance, this features an intake system over the engine and the positioning of the fuel tank under the seat for a much more balanced machine and lower centre of gravity. Also featuring is a new rear wheel spindle diameter for greater strength and less deflection of the swing-arm, a new triple clamp arrangement with less offset to improve rideabilty of the new chassis layout and weight transferal system, a new air filter for better efficiency of the new intake system ans a new plastic design in a fresh and aggressive style featuring a new seat arrangement and fresh graphics in an Italian theme
Other features include, a TM Racing 'Factory' rear shock absorber, Kayaba 48mm forks, billet machined aluminium hubs laced to anodised Excel rims, billet machined aluminium triple clamp with damped handlebar mountings, oversize taper bars, oversize 'wave' braking discs and a switchable twin map ignition system.
Single cylinder water cooled 4 stroke engine, double overhead camshafts operating titanium valves via a 'bucket' system, billet connecting rod with a forged piston, dry sump with twin rotor oil pump for recovery and distribution, downdraught battery-less Electronic Fuel Injection with a 46mm throttle body and a HGS 'bomb' type exhaust system. Electric start is also available as an option at the time of order.
