S&S, 883-1200 conversion piston kit. Std

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 3-1/2" 1200 bore only (see note). 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 04-22 883 XL models. Stock cylinder liners of 04-22 XL models are too thin to bore to 1200 size. Note: In any and all applications the technician must be able to judge components for their suitability in combination with the other engine components, prior to installation. It is of importance that a knowledgeable mechanic will install & make adjustments as required. The rider must follow standard break-in and riding procedures for overhauled engines.
