The 350 EXC‑F engine is equipped with two oil pumps. A pressure pump supplies reliable lubrication to the crankshaft, piston, balancer shaft and valve controls. It also ensures cooling of the ignition and lubrication of the clutch. A suction pump draws oil from the crankcase and uses it to lubricate the transmission. This creates a slight vacuum in the crankcase, which also increases engine performance.
The crankshaft drives a laterally positioned intermediate shaft that also acts as a balancer shaft, water pump drive and timing chain drive for the two camshafts. A hydraulic chain adjuster ensures reliable chain tension and consequently extremely precise valve timing.
The 350cc four-stroke engine, with state-of-the-art electronic fuel injection, provides a very broad useable rev range and distinguishes itself with dynamic yet strength-saving engine characteristics. With peak power of more than 45 hp, the 350 EXC‑F is powerful enough to beat every 450 in the E2 class.
