Description
The Hot Rods CBK0087 complete bottom end rebuild kit covers 03-13 Yamaha YZ 250 F 250cc, and it is the part you want on the bench before the engine comes apart, not after.
A bottom end refresh is the job most riders put off until the engine forces the issue. This kit exists so the whole job gets done at once: crankshaft, main bearings and seals, plus the complete top and bottom end gasket set with seals, all matched to the same fitment in one box. No half-finished rebuild waiting on a back-ordered seal, and no mixing three brands of parts inside one crankcase.
- Saves the shop-time and shipping cost of chasing individual gaskets, seals and bearings
- Stroker crankshaft options exist on some models if you want displacement while the cases are apart
- Hot Rods has built rebuild hardware for powersports engines for decades, so fitment data is proven
- Crankshaft, main bearing and seal kit, and full top and bottom end gasket set with seals in one box
- Assembled and trued to OEM specification so bearing clearances and runout are right out of the carton
- Stroker crankshaft option available on some models
Ordering the correct part number matters more on engine internals than anywhere else on the machine, which is why this listing is tied to 03-13 Yamaha YZ 250 F 250cc and nothing else. IPD Racing ships it with tracking so you can plan the build around it.
