Have the bore and piston assessed before ordering

The available standard, +0.25 mm and +0.50 mm descriptions identify different replacement sizes. A motorcycle’s age or mileage cannot tell you whether it has been rebored. Use the measured engine and planned machining work to choose the correct piston-and-ring combination.

Check the parts being retained as well as the size

For a ring-only repair, identify the fitted piston before choosing the matching ring set. For a piston-kit order, the supplied pin is already part of the package. Compare that contents list before adding the separate pin product.

Common questions

Are piston-pin clips supplied in either featured piston kit?

No. Both the standard and +0.25 mm kits explicitly exclude pin clips. Account for the appropriate clips separately when planning the piston replacement.

How many cylinders does one package cover?

Each featured piston kit and the +0.50 mm ring set covers one piston. Set the order quantity by the cylinders being repaired; a single listing is not a four-piston package.

Can I choose the +0.50 mm rings because the engine has high mileage?

No. Match the rings to the measured bore and fitted piston specification. The oversize marking identifies size, not a mileage-based repair recommendation.
