Compatibility: Yamaha Y15ZR

Variants & Setup

Larger jet sizes give a bigger stroke increase and are generally paired with a matching big-bore cylinder, piston, camshaft and carburetor/fuel tuning; consult your mechanic to match jet size to the rest of your build.

Installation & Package

Crankshaft installation requires a full engine teardown and should be done by an experienced mechanic, along with matching case clearance and balancing checks. Package: 1x complete crankshaft set.

Summary

HPSP Super Pro complete racing crankshaft for Yamaha Y15ZR, available in six stroke-increase (jet) sizes.

Important Notes

A larger stroke increase changes engine characteristics significantly and generally requires matching supporting parts (piston, cylinder, valve train); it is not a bolt-in upgrade on its own. This is a racing part intended for built/modified engines.
