VHM 10.80 -1.70 1.00 Cylinder head domeTM RACING 125 MX 125 - 2012 - 2015Ref : VHM0581 / VHMAE32223-B

This insert has a smaller volume and a higher compression ratio than our standard VHM insert, which means more torque at low and medium engine speeds. It improves acceleration and provides a greater sense of torque when exiting bends. However, bear in mind that this compromises top speed. The combustion chamber fits perfectly into the VHM cylinder head and is easy to replace. The last digits of the reference number are engraved on the insert for easy identification.

• More low-power reaction
• Ideal for deep sand tracks
• Quick adjustment
