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. The 350 cc 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 exceptional performance. The internals feature polished camshafts and DLC coated finger followers resulting in minimal friction and unsurpassed overall performance. Added to the design are larger titanium valves (36.3 mm intake and 29.1 mm exhaust) which allow the engine to rev freely up to the 13,400 rpm.
The 88 mm bore and 57.5 mm stroke cylinder features a large diameter and lightweight forged bridged-box-type piston by CP. As a result, the relatively low oscillating masses deliver exceptional power, high revs and a very wide power band. The compression ratio is 14:2:1.
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 shifting fork ensuring smooth and precise shifting. The gear lever is designed to prevent dirt build-up to ensure easy operation in the toughest conditions. An advanced gear sensor allows for specific engine maps in each gear.
The FC 350 features a Diaphragm Steel (DS) 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.
