Pistons by KB Performance Pistons
Used for boring 883 Sportsters to 1200, these KB High Performance pistons are made from Hypereutectic 390 alloy. This low expansion alloy allows for a tighter piston to wall running clearance compared to forged pistons. The pistons feature fully machined crowns and valve reliefs. The wrist pins are full floating. KB pistons are sold as pairs and include piston rings and triple wound spiral locks.
This piston series uses rings that are otherwise used on Shovelhead pistons.
Piston rings only available as .000” and .010”. Please measure if in need.
