PISTON KIT 86-07 CR80 49.00, WOSSNER 8237D200 HONDA MX

Wossner forged piston kit with a 49mm bore size (48.95mm actual), specifically designed for Honda CR80 models from 1992 to 2002 with a US bore. Manufactured in Germany, this piston kit features an elliptical design to ensure uniform bearing surfaces during heat expansion, improving durability and heat transfer within the combustion chamber. This engineering reduces localised pressure points, distributing thrust loads evenly and preventing piston collapse.

Features

• Forged piston construction for superior strength and design

• Optimised for efficient heat transfer from the combustion chamber to cylinder walls

• Elliptical design improves bearing surface uniformity under heat expansion

• Reduces risk of piston collapse by evenly distributing thrust loads

• Manufactured in Germany
