Unicam Valve Train

Unicam™ valve train features a carburized single camshaft that directly actuates two 36mm titanium intake valves. The camshaft exhaust lobe actuates two 31mm steel exhaust valves via a forked, low friction, roller rocker arm. A separate cam holder contributes to the compact design, which allows a remarkable 21.5-degree included valve angle and saves 13.3 ounces over a comparable DOHC system.
