The repositioning of the crankshaft and clutch shaft, together with the complete redesign of all the internal components as well as the crankcases, results in a 20 mm shorter engine. Weighing only 27.2 kg, the 58 horsepower 350 cc engine is 1 kg lighter than the previous generation engine and is mounted closer to the centre of gravity of the bike. The multifunctional counter balance shaft reduces vibrations while also driving the water pump and timing chain.
A new stiffer crankshaft is at the heart of the high power output, high-revving FC 350 engine. The plain big end bearing and two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
The cylinder head retains the DOHC architecture but features a completely redesigned combustion chamber, new ports, new camshafts and new valve springs. The DLC (Diamond Like Carbon) coating on the finger followers is 30 % harder, therefore reducing friction. Large, lightweight 36.3 mm diameter, 22.4 g titanium intake and 29.1 mm, 22.7 g titanium exhaust valves allow the engine to rev freely to the 13,400 rpm ceiling.
Cylinder & Piston
The lighter and lower 88 mm bore and 57.5 mm stroke cylinder features a large diameter and lightweight forged bridged-box-type piston by CP and relatively low oscillating masses, giving the engine strong power, high revs and a very wide power band. The compression ratio is 14:1.
