Vhm Cylinder Head Inserts
VHM insert
Sku: VHM-AE32353-E (5.55cc)
This insert has a higher volume / lower compression ratio than our VHM standard insert, meaning better over revolution characteristics and more top speed. However, keep in mind that this compromises bottom power reaction. The combustion chamber fits the VHM cylinder head perfectly and is easily changed. The last numbers of the part number are engraved into the insert for identification.
Use in combination with VHM head VHM-AA33217
Use the insert chart as a general guideline to select the insert depending on the fuel, track and elevation.
- More top
- Better for hard ground/enduro

This insert does not fit into an OEM head, only a VHM cylinder head. It's recommended to use good fuel against detonation.
