VHM Cyl. head nsert 125SX `07-15, TC125 `14-15 11.60 +0.40 0.90

This insert has a lower volume / higher compression ratio than our VHM standard insert for 12° piston, 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 AA33097 and VHM 12° piston APKT12511673
