Features
Building the
4-Stroke
of the future,
one engine at a time!
Surpass™ engines share features that include a helical gear-driven camshaft up front and a reliable rear updraft carb. Generous intake valves and CNC-machined parts add superior fit, power and compression. Rugged ringed pistons and ball bearing-supported crankshafts contribute smooth, trouble-free operation. Most also include rubber-sealed ball bearings, a reversible carb for easy installations and corrosion-resistant plating on the crankshaft, camshaft and piston.
