Billet Cylinder Head With Insert

• Product Details

  The MotoSport.com VHM Billet Cylinder Head With Insert includes ONE VHM Billet Cylinder Head and ONE VHM Cylinder Head Insert, each with the following features:

  VHM Billet Cylinder Head:

  The world famous golden VHM head with exchangeable combustion chamber is specially developed for optimal power output during the whole race and has an improved water duct. It's manufactured from a high-quality alloy and O-rings are used for the sealing.

  • Use VHM standard insert.
  • More engine power.
  • Better heat transference.
  • More resistance to detonation.
  • Exchangeable combustion chambers available.

  VHM Cylinder Head Insert:

  This insert has a higher volume / lower compression ratio, meaning better over-rev characteristics and more top speed. However, keep in mind that this compromises bottom power reaction. 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.

  • Use in combination with VHM head.
  • More top.
  • Best for hard ground / enduro.
  • Good resistance to detonation.
  • Note: This insert does NOT fit into an O.E.M. head.
