PISTON KIT 90-93 YZ125 56.50, WOSSNER 8114D050 YAMAHA MX

The Wossner 8114D050 piston kit features a 56.50mm bore (actual 56.44mm) and is engineered for superior strength and optimal heat transfer to cylinder walls. The forged, elliptically designed piston ensures uniform bearing surfaces under heat expansion, reducing localised pressure and evenly distributing thrust loads to prevent collapse. Made in Germany, this piston kit includes all necessary components for replacement and is compatible with specific Yamaha YZ125 models.
