VHM High-Compression Cylinder Head Insert for Beta RR 200 2-Stroke – 17.20cc

he VHM 17.20cc high-compression cylinder head insert is designed for Beta RR 200 2-stroke models equipped with the compatible VHM cylinder head. Its reduced combustion chamber volume increases the compression ratio compared with larger-volume inserts, delivering a more responsive engine character with increased bottom-end and mid-range torque.

The additional torque provides stronger acceleration and improved throttle response, particularly when driving out of corners or riding in conditions where immediate power delivery is essential. This setup is especially effective on deep sand tracks and technical off-road terrain, where increased low-end response can help maintain momentum.

The higher-compression configuration prioritizes torque and acceleration over maximum top-end performance, making it a performance-focused option for riders looking for a stronger and more aggressive power delivery in the lower and middle rpm range.

VHM inserts are precision-designed to fit the corresponding VHM cylinder head and can be changed quickly, allowing engine characteristics to be adjusted for different tracks, terrain, or riding preferences. Identification is simplified by an engraved part-number reference on the insert.

This insert must be used with VHM cylinder head AA33184-1 and is not compatible with the OEM cylinder head.
