MCB Pro-Series Engine kits are simply the highest quality engine rebuild kits available. Period!

We start with professionally re-manufactured OE crankshafts that are 100% disassembled, maganafluxed, gauged, indexed and trued to perfection.
We ONLY use Koyo and FAG bearings that exceed OE specs to ensure long life and replace all parts that show ANY wear at all.

These assemblies are built by skilled craftsmen that take pride in producing precision parts that can stand the abuse of a powersports environment.
Our MCB pistons are made to OUR specifications in an ISO9001 environment and have proven for many years to have better than OE durability while increasing overall performance.

MCB pioneered the SD Dual-ring piston design solving numerous problem all at once and we continue to refine each and every part we sell, giving the customer peace of mind that he is buying a premium, well engineered, product.
Our rings are manufactured by the exact same plant that provides rings for F1 teams /Ducati / and TRD Racing

The Pro-Series engine kits are COMPLETE with everything you need to rebuild your engine other than external items you may or may not want to consider;
(check valves, thermostats, oil lines, etc) but we have those all available on this site as well.
