Easy installation: no need to bore or split existing cases, just swap the cylinders (unless otherwise noted)
Cylinders are constructed from premium aluminum castings with cast-in iron liners, and feature black granite finish with highlighted cylinder fins
Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
