Specs At A Glance

Good To Know

Q: Is this piston a stock or oversize bore? A: It is a standard 95.00mm bore piston, so it matches the original cylinder bore rather than an overbore. Confirm your cylinder condition before ordering.

Q: Does this kit include everything for a full rebuild? A: It bundles the piston, crankshaft and gasket set, which covers the main internals for a top and bottom end job. Bearings and other wear items may still be needed separately.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
