Specs At A Glance

Good To Know

Q: Do I need to bore my cylinder for this piston? A: No. The 48.00mm piston is a standard-bore size made for a stock RM85 cylinder, so the bore must be within factory spec before assembly.

Q: Can I install this set without splitting the cases? A: No. A crankshaft replacement requires the engine cases to be split, so plan the job as a full top and bottom end rebuild.

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