The 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.
-More engine power
-Better heat transference
-More resistance to detonation
