The crankshaft drives an intermediate shaft on the side which in turn drives the coolant pump and the two camshafts via the cam chain while at the same time acting as a counter balancer. A hydraulic chain tensioner enesures reliable chain tension to achieve highly precise valve timings.
The 350cc 4-stroke engine with a state-of-the-art electronic fuel injection offers a very wide power band and is distinguished by a dynamic but fatigue proof power delivery. At over 45hp of maximum power, the 350 XCF-W is strong enough to beat any 450.
The 350 XCF-W engine is equipped with two oil pumps. A pressure pump provides reliable lubrication for the crankshaft, piston, counter balancer shaft and valve train. In addition, it ensures the cooling of the ignition and lubrication of the clutch. A scavenger pump draws oil from the crankcase to lubricate the transmission. This also creates a small vacuum inside the crankcase which increases engine performance.
