Best CRF230F Big Bore $$Bang!!
Increased compression and increased engine size in a complete kit... The bigger / higher compression piston is a quality made dedicated casting just for the CRF230F and it weighs within 2 grams of OEM for a perfectly balanced crank assembly... Kit is complete with a brand new cylinder and well made gaskets just for this bigger bore setup... No waiting for bore job on OEM cylinder... Open the box and complete install is ready to happen.... More power everywhere in the band... You can't beat the value/ simplicity of this upgrade kit.. no way...

Works great
Installed fairly easily and was up and running in no time. So far so good. Plenty more power over stock.
