KB414STD XR1200/Buell XB piston kit. STD

This KB Performance piston kit is engineered specifically for the 2008 to 2012 XR1200 and 2008 to 2010 Buell 1200 XB models. These forged aluminum pistons are designed for use with stock stroke and cylinders, offering a range of compression ratios depending on your head volume, such as 10.1:1 with 62cc heads. Sold as a set, they feature a domed head design and are manufactured using a T6 heat-treated process for superior strength. A key feature is the offset wrist pin design, which helps reduce engine noise and wear; just be sure to follow the orientation markings for the front and rear cylinders during assembly. These pistons provide the structural integrity needed for high-performance Sportster-based engines while maintaining the longevity expected from a premium street build.
