VHM 25.00CC 0.00 1.90 Cylinder head domeRef : VHM0297 / VHMAE32339-B

This insert has a smaller volume and a higher compression ratio, which translates into greater 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 change. The last digits of the reference number are engraved on the insert for easy identification.
