The FX 350 shares much of its engine and chassis architecture with the motocross FC 350, but is tailored for closed course off-road usage. With a maximum output of 58 hp, the FX 350 has a 450 rivalling power-to-weight ratio while retaining the light, agile handling of 250-class machines. This is matched with an advanced electronics package featuring launch control, switchable engine maps and traction control resulting in a versatile, high performance package. Include a larger 6-speed transmission, large fuel capacity and an 18-inch rear wheel and the FX 350 is one of the most advanced off-road machines created by Husqvarna Motorcycles.
The 350 cc DOHC engine weighs in at only 60 pounds and has a maximum power output of 58 hp. The engine is specifically designed with performance, weight and mass centralization as key criteria. As a result, all shaft arrangements are positioned to allow oscillating masses to occupy the ideal center of gravity while all parts are engineered to offer the best possible performance while adding the least possible weight.
The FX 350 features the same DOHC design as the FC 350 with polished camshafts and DLC coated finger followers reducing friction and improving 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 to the 13,400 rpm ceiling.
The FX 350 features an engine design with mass-centralization and weight reduction as the main goals. All the major components are positioned to achieve the best possible center of gravity. As a result, the motorcycle benefits from superb handling while ensuring a light and compact engine design.
A superior quality crankshaft is at the heart of the high output, high-revving FX 350 engine. The plain big end bearing featuring two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
