Finish and tolerances suitable for maintenance or engine rebuild interventions.
Compatible notably with Honda CRF 450 R (PE05) 2010, 2011, and 2012 in 450 cm³. Ideal for cylinder refurbishment operations or replacing a worn piston: check the bore and follow the manufacturer's recommendations during installation (piston/cylinder clearance, segment orientation, tightening torque). A professional spare part, it fits into engine preparation work on the track or regular maintenance.
