These pistons by KB for Harley-Davidson motorcycles are made from Hypereutectic 390 alloy. This low expansion alloy allows for a tighter piston to wall running clearance compared to forged pistons. All 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.
