With the agility of a 250 and a 450-rivalling power-to-weight ratio, the FC 350 strikes a competitive balance between power and handling. This appeals to both professional and amateur riders alike, making for a more user-friendly riding experience in all conditions. It is this versatility, paired with intelligent traction and launch control, which makes the FC 350 one of the most multitalented motocrossers on the market.
The 350cc DOHC engine weighs in at only 27.2 kg and has a maximum power output of 58 hp. The engine is specifically designed with performance, weight and mass centralisation as key criteria. As a result, all shaft arrangements have been positioned to allow oscillating masses to occupy the ideal centre of gravity while all parts are engineered to offer the best possible performance while adding the least possible weight.
The FC 350 features an advanced DOHC cylinder head layout meticulously engineered to deliver every fraction of performance. The internals feature polished camshafts and DLC coated finger followers, resulting in minimal friction and unsurpassed overall performance, allowing the engine to rev freely to 13,400 rpm.
Cylinder and 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.
A top-quality crankshaft is at the heart of the high output, high-revving FC 350 engine. The plain big end bearing features two force-fitted bearing shells to ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
The FC 350 features an engine design with mass-centralisation and weight reduction as the main goals. All the major components have been positioned to achieve the best possible centre of gravity. As a result, the motorcycle benefits from superb handling while ensuring a light and compact engine design.
High-pressure die cast production processes keep the overall weight to a minimum, resulting in a thin wall thickness while retaining reliability. The iconic Husqvarna logo adorns the bronze finished crankcase covers.
Produced by Pankl Racing Systems, the compact 5-speed gearbox features a low-friction coating on the its fork that makes shifting smooth and precise. The gear lever features a design that prevents dirt build-up and ensures easy operation in the toughest conditions. An advanced gear sensor allows for specific engine maps in each gear.
The MY20 FC 350 features a DS (Diaphragm Steel) clutch. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs. The clutch basket is a single-piece CNC machined steel component that allows the use of thin steel liners and contributes to the compact design of the engine.
