VHM cylinder head insert for SUZUKI RM 125 from 1998 to 2003. Each version shows its three key figures: chamber volume, piston height and squish.
The VHM AE32088-019 cylinder head insert is designed for SUZUKI RM 125 from 1998 to 2003. The insert forms the combustion chamber of the VHM head. Its volume sets the engine's compression: a small volume gives more bottom end and mid-range, a larger volume keeps the engine smoother and longer-revving.
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.

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