NOS Wiseco pistons

Wiseco Piston Stock Guide

Pistons must be matched by identification and measurements, not appearance alone. A shelf or box photo does not establish that a complete kit or a particular oversize is available.

• Bike year, make, model, engine size and any known engine or cylinder changes.
• Photos of the piston crown, underside and packaging labels, including Wiseco part numbers and size or oversize markings.
• The cylinder bore measurement supplied by your machinist, plus the required piston size and pin diameter if known.
• Whether you need a piston only, rings, pin, clips or a complete kit; include existing ring and piston identification.

Have a qualified machinist confirm bore condition and the clearance specified for the exact piston before ordering or machining. Mike must confirm the contents and condition of any individual package.

Photos show an assortment, not a promise of fitment. Ask Mike to confirm the exact item, quantity, condition, price and shipping before ordering.
