Description
ENGINE
When it comes to versatility, the DOHC 350 cc engine is second to none. By sharing much of its architecture with the 250 cc engine, the FE 350 delivers a fine balance between 450-rivaling power and lightweight 250 handling.
CYLINDER HEAD
A new casting with a lateral coolant outlet gives the cylinder head a new layout, and 200 g weight saving. Internally, the DOHC layout also features new camshafts with optimized timing and low-friction DLC coated finger followers. Lightweight titanium valves – 36.3 mm intake and 29.1 mm exhaust – a new cylinder head cover, spark plug, and spark plug connector all aid in delivering optimal performance.
CYLINDER AND PISTON
Featuring a new cooling architecture and paired with a lightweight forged bridged-box-type piston, the 88 mm bore cylinder is refined to deliver exceptional power. These updates also result in lower oscillating masses, higher revs and a very wide power band. The piston crown is also optimized to fit perfectly in the high compression combustion chamber and together with a new cylinder head gasket increases the compression ratio from 12.3:1 to 13.5:1.
CRANKSHAFT
The crankshaft has been upgraded to improve overall reliability and guarantee long service intervals of 135 hours. This has been made possible by a new bushing-type bearing at the connecting rod and two force-fitted bearing shells at the big-end bearing. Additionally, a new oil supply to the main bearing is integrated within the engine casing.
