Frequently Asked Questions

Q: Does this kit include the rings and wrist pin?
A: Yes, the Wiseco kit is a complete assembly including the piston, rings, wrist pin, and necessary circlips for a full installation.

Q: Is this piston suitable for high-performance racing?
A: While this forged piston is significantly stronger than OEM, it is designed for multiple-purpose riding and offers excellent reliability for trail, street, and light track use.

Expert Pro-Tip: Always check your cylinder-to-piston clearance with a feeler gauge during installation. Even with a high-quality forged piston, the cylinder bore condition is critical. If your cylinder wall has deep scratches or is out of round, no new piston will seal correctly; consider having the cylinder honed or bored to match the new piston for maximum longevity.
