VHM Insert Yamaha YZ65 2018 - 2024 (6.80cc)

This insert has a lower volume / higher compression ratio, meaning more low and middle range torque. This improves acceleration and gives an increased torque feeling when exiting corners. However, keep in mind that this compromises top speed. The combustion chamber fits the VHM cylinder head perfectly and is easy to change. The last numbers of the part number are engraved on the insert for identification.

Use in combination with VHM head AA33174

More bottom power reaction
Best for deep sand tracks
Quick to adjust
The insert does not fit into an OEM head, only a VHM cylinder head.
