KB924CSTD Performance, piston set std

This KB Performance forged piston set is the go-to choice for converting a 1986 to 2022 Harley-Davidson Sportster XL883 into a 1200cc powerhouse. These standard-sized pistons are engineered to work seamlessly with unmodified 883 heads, delivering a 10.1:1 compression ratio with a 51cc head. Manufactured from 4032 alloy, these pistons offer superior structural integrity and the ability to flex under high-stress conditions like detonation. The kit is sold as a set and includes wrist pins, retaining rings, and piston rings. Note that for 2004 and later XL models, you must use 1200cc cylinders as the stock 883 liners are too thin for boring. Because these feature offset wrist pins, pay close attention to the front and rear orientation during installation to ensure proper engine geometry.
