Description

The Wossner Piston Kit features enhanced piston pin oiling slots, radial boss machining, and annular grooves to ensure superior wrist pin lubrication. This reduces friction and wear, extending the life of your engine. The lightweight piston design, combined with a tight piston wall clearance, contributes to a quieter running engine. A skirt coating minimizes friction and aids in break-in, while a ring land treatment enhances ring seal and oil control. Where applicable, a double-bridged forging design adds strength and durability. The piston's forged aluminum alloy construction ensures reliability under demanding conditions, with a 77.96mm piston size designed for a 78.00mm bore and 52.20mm stroke length. The 13.5:1 compression ratio delivers increased power and responsiveness. This kit provides everything you need for a complete piston replacement.
