§ 02 / About this part
What it is
The VERTEX PISTON KIT Ø 66.40 B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This B-size kit provides the correct tolerances for a cylinder that has worn past its initial A-spec. It sits in the engine and is essential for maintaining the compression needed for crisp throttle response. In 2-stroke engines, this component acts as a valve and is subject to significant wear from the ports. Replacing it at the recommended intervals prevents the assembly from slapping and damaging the cylinder walls. The kit includes the rings, pin, and clips. Verify your bore size with a dial gauge before installation. Always use fresh gaskets for the rebuild.
