106-5548 883-1200 conversion piston kit. Std

Converting a Sportster from 883cc to 1200cc is one of the most effective ways to wake up an XL, and this S&S kit makes it straightforward. These standard bore forged pistons are designed for 1986 to 2022 XL883 and 1986 to 1987 XL1100 models. They are engineered to work with stock 883 heads, providing a healthy 9.5:1 compression ratio without requiring any case machining. For 1986 to 2003 models, you can simply bore your stock cylinders, while 2004 to 2022 models will require new 1200cc cylinders due to thinner liners. This kit is sold as a set and includes forged pistons, rings, wrist pins, and clips. It is a proven way to gain significant horsepower and torque while maintaining S&S reliability.
