With the agility of a 250 and a 450-rivalling power-to-weight ratio, the FX 350 strikes a competitive balance between power and handling. This appeals to both professional and amateur riders alike, as a user-friendly riding experience is guaranteed in all conditions. With considered revisions to the engine and chassis for 2023, together with advanced electronics to further enhance performance, the FX 350 is a highly capable off-road machine. Complete with a new, Swedish-inspired white, yellow, and grey colour scheme, which is applied to redesigned bodywork, the striking aesthetics, improved ergonomics, and flatter seat profile clearly indicates the continued development of the FX 350.

Features may include:

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 59.9 lbs (27.2 kg), the 350 cc 4-stroke engine centralises mass and aids the anti-squat behaviour of the whole chassis.

Cylinder head

Fully redesigned for 2023, 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. Revised valve timings work in perfect harmony with the redesigned camshaft which now features a new bearing bridge designed to increase stiffness and improve 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. For 2023, the compression ratio is increased to 14.6:1 for improved torque and peak power.

Crankshaft

At the heart of the high-output, high-revving FX 350 engine is the crankshaft which 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 revised (DS) Diaphragm Steel clutch. Engineered from a single piece of CNC-machined steel, the redesigned clutch basket accommodates the new gearbox and allows the use of thin steel liners, which contribute to the compact design of the engine.
