CRANKSHAFT ASSY STROKER

Stroker Crankshaft

Factory assembled and trued to OEM specifications

Drop in replacement crankshaft requires no modification unless noted

CNC machined and dynamically balanced to suit the increased stroke

Add +2.00 mm to +4.00 mm of stroke depending on application

Uses stock piston unless noted

Main bearings not included

Can be matched with Cylinder Works Big Bore cylinders to get significant displacement and horsepower gains

Not re-buildable as the rods are shorter than OEM.

+4.00 mm stroke increase makes 209 cc displacement with standard piston. IMPORTANT: Head Chamber area must be machined 2.00 mm deeper and the engine cases will need to be bored out to accept the longer stroke crank.
