Product description
Introducing the Big Bore Kit, designed to enhance your motorcycle's performance while maintaining compatibility with stock cylinder heads. This kit offers an easy installation process—there's no need to bore or split existing cases; simply swap out the cylinders (unless otherwise specified). Crafted from premium aluminum castings with durable cast-in iron liners, the cylinders ensure longevity and reliability.
Each kit includes everything you need for a complete upgrade: cylinders, pistons, rings, and all necessary gaskets (head, base, and exhaust). Available in a sleek black or silver powder-coat finish, this product is proudly made in the U.S.A.
Please note that this project requires a skilled technician for assembly. It is essential for the assembler to check all clearances and assembly specifications to ensure optimal performance. This kit is not recommended for trike models. Elevate your ride with the Big Bore Kit and experience the difference in power and efficiency!
