Quality Item CR250
Crank looks good and has nice machine work done to it. Gasket kit is very nice with only 1 o-ring missing for cases (but includes both water pump seals!) Main bearings are quality Koyo brand - Same as OEM.

I was very pleased with the kit. the bearings are koyo (oem in many quads). i would say this kit is as good or better than stock, at a much better price. the gasket kit is very good also.
