VHM 5.00 +0.40 0.80 Cylinder head domeRef : VHM0620 / VHMAE32167-101

This insert has a higher volume and lower compression ratio than our standard VHM insert, resulting in better overspeeding characteristics and a higher 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 replace. The last digits of the reference number are engraved on the insert for easy identification.

• Higher up
• Ideal for hard/enduro surfaces
• Good resistance to detonation
