Pistons, rings, gaskets, clutch kits, bearings and rebuild parts for Honda CRF250R, CRF450R, CRF150R and the CRF trail range, from ProX, Vertex, Wiseco, Hinson and the factory.
Honda engine parts are sold by model and year range, and the RX shares the R engine of the same year. The CRF trail bikes each take their own.

A race ridden 125 wants a new piston every 20 to 30 hours and a 250 every 40 to 50. Trail bikes go longer. Rings alone will do at the halfway mark if the bore is good.
No. A top end on a two stroke is a head, barrel, piston and gaskets, done with the engine in the frame. Four strokes are the same job with valves to check while you are in there.
