Used to convert a stock 883cc or 1100cc Sportster to 1200cc. Gives 1:9.5 CR with stock heads. Requires boring of stock cylinders to the stock 3.5" 1200 bore only.
Other modifications are not required. Works with stock 883 cylinder heads and cylinders, stock cases do not require boring. Kit comes complete with forged pistons, rings, wrist pins and clips.
NOTE: 1200cc cylinders must be purchased for 2004-Up 883 XL models. Stock cylinder liners of 2004-Up XL models are too thin to bore to 1200 size.
