Stroker crankshaft

Assembled and aligned at the factory to OEM specifications
Direct replacement crankshaft, no modifications required unless otherwise stated
CNC machined and dynamically balanced to accommodate increased stroke
Adds +2.00 mm to +4.00 mm of stroke depending on application.
Uses original piston unless otherwise stated
Main bearings not included
Can be combined with Cylinder Works Big Bore cylinders for significant increases in capacity and power.
Not rebuildable, as the connecting rods are shorter than OEM.
The +4.00 mm stroke increase results in a 209 cc capacity with a standard piston.
IMPORTANT: The cylinder head chamber must be machined 2.00 mm deeper and the crankcases must be ground to accept the long-stroke crankshaft.
