VHM – Cylinder Head Insert
The VHM combustion chamber insert is designed for use with VHM cylinder heads. Engineered for precision tuning, this insert allows riders and engine builders to fine-tune compression and power delivery to suit specific riding conditions.
Performance Overview
- Stronger low to mid-range power
- Improved acceleration out of corners
- More responsive throttle feel
Because of the higher compression, it may slightly reduce top-end over-rev compared to larger chamber options—making it ideal for tighter tracks or technical riding conditions.
