2024 Husqvarna® FC 350

With the agility of a 250 and a power-to-weight ratio rivalling the 450, the FC 350 strikes a competitive balance between power and handling. This appeals to both professional and amateur riders alike, creating a user-friendly riding experience in all conditions. With considered revisions to the engine and chassis, the FC 350 comfortably retains its position as one of the most multi-talented motocross bikes on the market. 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 indicate the continued development of the FC 350.

Features may include:

• Engine

The FC 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 access 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

A large 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. Engine responsiveness is further improved thanks to optimised valve guides and valve shaft diameters precisely engineered using computational fluid dynamics (CFD).

• Crankshaft

At the centre of the high-output, high-revving FC 350 engine is a crankshaft featuring a plain big end bearing rotating on two force-fitted bearing shells, ensuring maximum reliability and durability, guaranteeing long service intervals of 90 hours.

• Crankcases

Designed for optimised mass centralisation, the FC 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 FC 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.
