FX 350

FX 350

Continuing to offer the agility of a 250 with a peak power to rival a 450, the FX 350 delivers the perfect blend of rideability and proven performance. A new 6-speed gearbox with ratios designed for cross country racing, together with a specific engine map engaged in each gear, ensures every rider will benefit from a controllable power delivery at all speeds. Together with a new frame and updated suspension settings, an unrivalled riding experience is guaranteed. With the addition of a slightly taller and wider seat and ergonomic bodywork, including revised radiator shrouds, movement on the FX 350 remains effortless. New, Swedish-inspired graphics, applied using in-mold technology, provide a distinctive and long-last look.

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.
