The new FX 350 engine is designed to deliver maximum performance. For 2023, the repositioning of all major engine components and shaft arrangements enhances overall handling with the design improving anti-squat behaviour from the whole chassis. The engine is tilted two degrees backwards and is 8 mm shorter in height to further centralise mass. Weighing just 59.9 lb, the new 350cc 4-stroke engine produces a higher and more usable power output.

ENGINE
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 & PISTON
An 88 mm bore and 57.5 mm stroke cylinder features a compression ratio of 14:1 and a large diameter yet lightweight forged bridged-box-type piston. As a result, the low oscillating mass delivers exceptional power, high revs and a very wide power band.
CRANKSHAFT
At the heart of the high-output, high-revving FX 350 engine is a crankshaft featuring a plain big end bearing featuring two force-fitted bearing shells, ensuring maximum reliability and durability, guaranteeing long service intervals of 100 hours.
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.
