883 to 1200cc Conversion Kit for 1986-2019 HD® Sportster
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.
