01. Faster and wiser
Engine
The FX 350 engine is designed to deliver maximum performance with all major engine components and shaft arrangements positioned to enhance overall handling. Weighing just 27.2 kg, the 350 cc 4-stroke engine centralises mass and aids the anti-squat behaviour of the whole chassis.
Cylinder head
The DOHC cylinder head offers improved durability and serviceability, with diamond-like carbon (DLC) coated finger followers to guarantee minimal friction and optimal performance. These actuate large titanium valves, 36.3 mm for the intake and 29.1 mm for the exhaust, which optimise gas flow for strong, usable power across the rev-range, all the way up to the 13,400 rpm limit. Valve timings work in perfect harmony with the camshaft, which features a bearing bridge design for stiffness and easy serviceability.
Cylinder and piston
An 88 mm bore and 57.5 mm stroke cylinder is professionally engineered from high-strength aluminium for maximum reliability and houses the high performance forged bridged-box-type piston from CP. The compression ratio is 14.6:1 for exceptional torque and peak power.
Crankshaft
At the heart of the high-output, high-revving FX 350 engine is the crankshaft. This features a plain big end bearing rotating on two force-fitted bearing shells for maximum reliability and guarantees long service intervals of 90 hours.
Crankcases
Designed for optimised mass centralisation, the FX 350 crankcases house all internal components in the perfect position to achieve the ideal centre of gravity. Manufactured using a high-pressure die cast production process, the result is a thin, exceptionally strong wall thickness at the lowest possible weight.
DS clutch
The FX 350 features a diaphragm steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the clutch basket allows the use of thin steel liners that contribute to the compact design of the engine.
Gearbox
Produced by Pankl Racing Systems, the new 6-speed gearbox is extremely light and durable and features optimised gear ratios exclusive to the FX 350. Specific engine maps for each gear ensures the best performance possible. Integrated on the shift drum, the Quickshifter can be activated via the Map Select Switch to further aid smooth upshifting.
