VHM Insert KTM 65SX 09-23 / Husqvarna TC65 17-23 / GasGas MC65 21-23 (5.00cc) VHM 12° piston

This insert has a lower volume / higher compression ratio than our VHM standard insert, 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 AA33112 and VHM 12° piston APKT06521722.
