Husqvarna FE350 2022

Engine

The DOHC 350cc engine is unrivalled in terms of versatility. Sharing much of its architecture with the FE 250 engine, the FE 350 delivers a significant increase in power and torque, enough to get close to a 450, while maintaining its lightweight character.

Cylinder head

The FE 350 features an advanced DOHC cylinder head layout meticulously engineered to deliver performance and reliability. Internally, the DOHC layout features polished camshafts and low-friction DLC coated finger followers. Together with lightweight titanium valves – 36.3 mm intake and 29.1 mm exhaust – they aid in delivering optimal performance.

Cylinder and piston

The 88 mm bore and 57.5 mm stroke cylinder features a compression ratio of 13.5:1 and a lightweight forged bridged-box-type piston. As a result, the low oscillating mass delivers exceptional power, high RPM and a broad, usable power band.

Crankshaft

The crankshaft is optimised for overall reliability to guarantee long service intervals of 135 hours. This has been made possible by use of a connecting rod with a bushed small-end and two force- fitted shells at the big-end bearing. Additionally, an oil supply to the main bearing is integrated with the engine cases.​

Counter-balancer shaft

In order to counteract the rotational force of the crankshaft and reduce vibration, the FE 350 engine uses a multifunctional counter-balancer shaft which also drives the water pump and timing chain.

Crankcases

The engine cases are engineered to arrange the shafts for the ideal centre of gravity. The casings are manufactured using a high-pressure die-cast production process, resulting in thin wall thickness while retaining exceptional reliability. The iconic Husqvarna logo adorns the bronze-finished crankcase covers.

Gearbox

A 6-speed gearbox from Pankl Racing Systems uses 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 350 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 making the 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.
