Cylinder & Piston Conversion Kit for Harley-Davidson® Sportster®
Convert 883cc Harley-Davidson® Sportster® models to 1200cc
S&S 883cc to 1200cc cylinder and piston conversion kits make it easy to upgrade any 883cc Harley-Davidson® Sportster® model to 1200cc. Kits include cylinders, rings, and gaskets. Available in silver powdercoat and black wrinkle powdercoat finishes.
S&S cylinders match the fin profile on 1986-’03 cylinder heads. Although there is a slight difference in the fin profiles of S&S cylinders and stock 2004 –’13 cylinder heads (shown above), the look is generally not considered to be objectionable. You decide!
Riders with 883cc engines can satisfy piston envy quickly and easily with the 883-1200 cylinder and piston conversion kit.
Boost any 883cc Harley-Davidson® Sportster® to 1200cc. No machine shop? No problem, no machining is needed. Don’t want to rebalance your stock 883cc flywheels? You don’t need to since these pistons weigh the same as stock 883 pistons. Cylinder head modification is also not needed. The dished piston dome keeps compression down to a streetable 9.4:1 with stock 883cc heads. Installing this kit takes the same time as replacing a stock top end. It’s just more fun when you’re done.

The cylinder fin profile does not perfectly match the fins on 2004 and later stock heads, but the difference is not considered to be objectionable. See Photos.
S&S does not recommend boring 2004 and later 883cc cylinders from 3" to 31/2" bore to increase engine displacement to 1200cc due to changes in factory cylinder and liner. A smaller O.D. liner and large chamfer on the bottom of the spigot make
boring the 883 cylinder not possible. New cylinders are
