VHM CYLINDER HEAD INSERT E (5.55cc) KTM 65 SX 24-25 / HUSQVARNA TC65 24-25 / GASGAS MC65 24-25
This insert has a higher volume / lower compression ratio than our VHM standard insert, meaning better overrevolution 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 easy to change. The last numbers of the part number are engraved to the insert for identification.
Use in combination with VHM head 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
- Quick to adjust
- Good resistance to detonation
This insert does not fit into an OEM head, only a VHM cylinder head. It's recommended to use good fuel against detonation.
