§ 02 / About this part
What it is
Vertex piston kit Ø47.50 D to fit the Honda CR85R, model years 2003–2007, and Honda CR85RB, model years 2003–2007.
Restore compression and engine response during your next top-end rebuild. This component sits at the heart of your engine, reciprocating within the cylinder bore to drive the stroke. Pistons require replacement as skirts wear and ring tension fades, leading to blow-by and power loss. The specific sizing—A, B, C, or D—allows for precise clearance matching against your cylinder's current wear or plating state. Verify ring end gap and ensure circlips are seated correctly during assembly. Position the crown arrow toward the exhaust port to avoid port snagging. Regular service intervals prevent catastrophic failure and maintain peak performance on the track or trail.
