01. Progressive performance
Engine
The current generation engine is designed for maximum power, which is delivered in a controllable way to suit all kinds of enduro riding. Inside, all major components and shaft arrangements are positioned close to the centre of gravity to reduce the effects of rotational inertia, which leads to agile handling. Positioned in the chassis to further centralize mass, the powerful 350 cc 4-stroke engine weighs just 28.8 kilograms.
Cylinder head
Featuring finger followers treated with a Diamond-Like Carbon (DLC) coating, the DOHC cylinder head is engineered for high-level enduro performance. For optimal gas flow, the titanium intake valves are 36.3 mm while the exhaust valves are 29.1 mm. This allows the FE 350 to rev freely and produce strong yet controllable power throughout its rev-range.
Cylinder and piston
An 88 mm bore cylinder and forged bridged-box-type CP piston combine to create a compression ratio of 13.7:1. As a result, the low oscillating mass delivers strong and controllable power. High-strength aluminium is used to manufacture both the cylinder and piston, with both components professionally engineered for outstanding performance and reliability.
Throttle body
The FE 350 features a 42 mm Keihin throttle body optimised for throttle response. The injector is positioned to ensure the most efficient flow into the combustion chamber with the throttle cable mounted directly without a linkage for an enhanced response.
