Upgrade your Harley-Davidson XL1200 with the REVOLUTION PERFORMANCE LLC 1250 cc Big Bore Cylinder Kit, designed to deliver increased horsepower and improved engine efficiency. This kit features aerospace-grade all-aluminum cylinders with a nickel-silicon-carbide (NSC) electroplated bore, which reduces friction and enhances durability. The NSC coating provides lower engine temperatures and a longer lifespan, making it an ideal choice for high-performance applications. The kit includes a pair of all-aluminum NSC-coated bore cylinders, custom-forged pistons with high-tension rings specifically engineered for NSC cylinders, and a head/base gasket set. Replacement gasket sets are available separately for convenience. Made in the USA, these cylinders do not require sleeving, allowing for larger bore sizes to maximize performance. For optimal assembly, upgraded cylinders studs and head bolts are recommended to ensure secure mounting and reliable operation.
