      The VHM AE32272-A cylinder head insert is designed for KTM EXC 250, SX 250, HUSQVARNA TC 250, TE 250 and GAS GAS EC 250, MC 250 from 2017 to 2023. On a VHM cylinder head, the combustion chamber is an interchangeable insert (or dome). Changing the insert changes the chamber volume, and therefore the compression ratio, without modifying the head: you adapt the engine to the fuel, the terrain and your riding.

      Key features

      • Each version shows its three key figures: chamber volume, piston height and squish.
      • Change the compression without machining the head, to suit the fuel and the terrain.
      • Part number engraved on the insert.
      • Fits VHM cylinder heads only.

      Specifications

      • Brand: VHM
      • Manufacturer part number: AE32272-A
      • Engine: 2-stroke

      When to change the insert?

      • Switch to a different fuel (98 or race fuel with a higher octane rating).
      • Engine knocking (pinking) or running hot: compression too high for the fuel.
      • You want more torque on tight or sandy terrain.

      Change the insert when you change fuel or type of riding, or if the engine pinks. The insert's three dimensions (volume, piston height, squish) must match your engine.

      Fitting tips

      1. The insert is changed with the cylinder head removed.
      2. Check that the actual height of your piston at top dead centre matches the figure given for the insert.
      3. Replace the VHM head O-rings every time you take it apart.
      4. Check the squish with solder wire before riding.
      5. Tighten the head to the recommended torque, in a criss-cross pattern and in several stages, then fit a new spark plug.

      Why VHM?

      Since 1995, VHM has been designing racing engine parts for two-strokes: cylinder heads with interchangeable inserts, combustion chamber inserts, crankshafts and connecting rods. A specialist brand, used to fine-tune an engine's power without transforming it.
