VHM 5.70 +2.50 0.75 Cylinder head domeRef : VHM0283 / VHMAE32353-F

This insert has a greater volume and a lower compression ratio than our standard VHM insert, resulting in better overspeeding characteristics and increased top speed. However, bear in mind that this compromises power response at low revs. The combustion chamber fits perfectly into the VHM cylinder head and is easy to change. The last digits of the reference number are engraved on the insert for easy identification.

• Higher up
• Ideal for hard/enduro surfaces
