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.

Great kit
This is a great conversion kit. I took my time and installed in a few days without any problems. Bike runs great with plenty of torque.

Good stuff!
This is a sweet kit. Using the 883 heads on this larger bore kit yields a very fun increase in the bottom and mid-range performance and the higher RPM performance ain't bad either considering the induction limitations of the 883 heads. If you keep your stock 883 gearing the bike will be a blast on surface streets. Easy to install plus quality parts, it adds up to a very worthwhile modification to your (formerly) 883 Sportster. Do it!
