VHM Insert Yamaha YZ85 2019 - 2024 (8.00cc, +0.00, 1.30) for 12° piston

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 AA33176 and VHM 12° piston APYZ08521757

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.
