FULL DESCRIPTION
Wossner Piston Kit 8187D200 for Yamaha YZ80
Engineered for performance and durability, the Wossner 8187D200 piston kit is designed to enhance your Yamaha YZ80 motorcycle. This kit features a precisely machined 50.00 mm bore, suitable for +2.00 mm oversize applications, ensuring a perfect fit and optimal compression.
Crafted in Germany, Wossner pistons utilize a forged construction, providing superior strength and resilience compared to cast alternatives. This advanced manufacturing process allows for excellent heat dissipation, crucial for maintaining engine integrity under demanding conditions. The unique elliptical profile of the piston is engineered to distribute thrust loads evenly across its surface as it expands with heat. This intelligent design minimizes localized stress points, significantly reducing the risk of piston failure and promoting longer engine life.
This comprehensive kit includes all the necessary components required for a complete engine rebuild, offering convenience and assurance of quality for your Yamaha YZ80.
