Good To Know

Q: Does this kit include everything for a full rebuild? A: It bundles a 54.00mm standard bore piston, a crankshaft assembly, and a gasket set so the main internal parts arrive together. Inspect bearings and seals during teardown and replace anything worn beyond spec.

Q: Will the 54.00mm piston fit my stock cylinder? A: The 54.00mm size matches a standard bore YZ125 cylinder that has not been overbored. Measure your cylinder and confirm the bore before ordering.

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