Husqvarna FE250 2022

Engine

The 250cc engine is designed to be powerful, light and compact. All major components are carefully positioned with the engine and gearbox shafts arranged to ensure the overall package delivers the best performance and handling characteristics. As a result, the engine weighs only 27.9 kg while retaining a torquey character to make the FE 250 accessible to both professionals and amateurs.

Cylinder head

The cylinder head features advanced technology aimed at reducing weight and drag: from the low friction surface in which the twin overhead camshafts rotate, to the four lightweight titanium valves – intake 32.5 mm, exhaust 26.5 mm – actuated by DLC (diamond-like carbon) coated finger followers. This helps the engine to rev freely while maintaining smooth, efficient power throughout the RPM range.

Cylinder and piston

The cylinder is taken from the successful FC 250 motocross model and features the same 78 mm bore. It also houses a forged bridged-box-type piston, professionally engineered from high-strength aluminium. The compression ratio of 13.8:1, in combination with the state-of-the-art cylinder and cylinder head gasket, provides outstanding performance and reliability.

Crankshaft

The plain big-end bearing features two force-fitted bearing shells to ensure maximum reliability and durability, guaranteeing long 135-hour service intervals.​

Counter-balancer shaft

In order to counteract the rotational force of the crankshaft and reduce vibration, the FE 250 engine uses a multifunctional counter-balancer shaft which also drives the water pump and timing chain.

Crankcases

The FE 250 engine is designed to be compact and centralise rotating masses. As a result, the crankcases are engineered to arrange the engine and gearbox shafts for the ideal centre of gravity and integrate the oil supply to the main bearing. The casings are manufactured using a high-pressure die-cast production process and are optimised for minimal weight while retaining exceptional reliability. The iconic Husqvarna logo adorns the bronze-finished crankcase covers.

Gearbox

The 6-speed gearbox from Pankl Racing Systems provides specific wide-range enduro-type gearing. Additionally, a gear sensor allows the EMS to deliver specific engine maps tailored to each gear.

DDS clutch

The FE 250 features a DDS (Dampened Diaphragm Steel) clutch. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs to make clutch operation very light, while also integrating a damping system for better traction and durability. The clutch basket is a single-piece CNC-machined steel component that allows the use of thin steel liners contributing to the compact design of the engine. The BRAKTEC hydraulic system ensures perfect modulation in all conditions.
