Hailed as the most premium 250 4-stroke motocross motorcycle available, the Husqvarna FC 250 is engineered to keep ahead of the field. Featuring a lightweight and compact motor and PANKL gearbox with advanced electronics and ergonomics, the FC 250 maintains the leading position in the 250 4-stroke class.
Engineered to ensure class-leading performance and handling characteristics, all major engine components and shaft arrangements are carefully positioned closer to the centre of gravity to reduce the effects of rotational inertia. The 250cc 4-stroke engine is also light, tipping the scales at only 26.1 kg, but is also remarkably powerful with an overall power output of 46 hp.
Featuring finger followers treated in a Diamond-like Carbon (DLC) coating, the DOHC cylinder head is engineered for high-level performance. Large titanium valves – 32.5 mm intake and 26.5 mm exhaust – aid the motor to rev freely towards its 14,000-rpm limit, while maintaining smooth, efficient power throughout the rev-range.
Cylinder & Piston
The 78 mm bore cylinder houses a forged bridged-box-type piston made by CP. Both the cylinder and piston are professionally engineered from high strength aluminium resulting in outstanding performance and reliability. The compression ratio is 14.4:1.
The crankshaft is designed to offer the best possible performance while being placed in the perfect position to centralize oscillating masses for optimal handling. The plain big end bearing features two force-fitted bearing shells, ensuring maximum reliability and durability and guaranteeing long service intervals of 100 hours.
All Husqvarna motocross motors are designed with mass centralisation and weight reduction as the main criteria. As a result, the crankcases are designed to house the internal components of the engine in the perfect position to achieve the ideal centre of gravity while adding the least possible weight. The casings are manufactured using a high-pressure die-cast production process. The result is thin wall thickness and exceptional reliability. The iconic Husqvarna logo adorns the bronze finished crankcase covers.
Produced by Pankl Racing Systems, the 5-speed gearbox is designed to be extremely light and durable while featuring specific motocross specific ratios. The shifting fork has a low-friction coating for smooth shifting, while the gear lever is designed to prevent dirt build-up and ensure perfect gear selection in all conditions. An advanced gear sensor allows for specific engine maps delivering the best possible performance in each gear.
The FC 250 features a (DS) Diaphragm Steel clutch. The clutch basket is engineered from a single-piece of CNC-machined steel that allows the use of thin steel liners and contributes to the compact design of the engine. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs.
