Honda Engine Parts

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.

Buy the gasket set with the piston and the job is done in one order. Set your bike at the top of the store and the list narrows to parts with confirmed fitment. Members pay the member price on every product in the store and get free standard shipping on orders over $10. Membership is $5 for the first month.

    Questions riders ask

    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. Every listing names the model and year range; set your bike at the top of the store or message us with the model, year and what you are rebuilding.

    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.

    Not sure what fits? Set your bike at the top of the store and every list narrows to parts with confirmed fitment, or message us with your model and year.
