Upgrade your Harley Sportster with the S&S CYCLE 1200cc Conversion Cylinder Kit, designed for models from 1986 to 2021. This kit transforms your engine to a 1250 cc displacement, delivering increased power and performance. The forged pistons feature larger-than-stock valve pockets that accept up to 2.00-inch valves, enabling improved airflow and combustion efficiency. Coated piston skirts with measurement windows and the S&S logo ensure durability and easy inspection. The installation requires no machining or rebalancing, making it a straightforward upgrade for seasoned mechanics and enthusiasts alike. Included in the kit are S&S 1250 cc pistons with rings and wristpins, 3-9/16-inch bore cylinders, MLS (Multi-Layer Steel) head, base, and exhaust gaskets, along with assembly lube and detailed instructions. The parts are proudly made in the USA, ensuring high quality standards. Please note that this kit is not compatible with XR1200 models and 883 models will need XL1200 cylinder heads to achieve correct compression ratios. For optimal performance, additional upgrades such as CNC porting, performance cams, and exhaust and intake systems are recommended to maximize power output and efficiency.
