Product Description
This 27.00cc VHM insert is designed for Beta RR 300 2T, RR 300 2T Racing, and RR 300 2T X-PRO models. With a lower volume / higher compression ratio than the standard insert, it significantly enhances low and mid-range torque, improving throttle response and acceleration when exiting corners. Ideal for deep sand tracks and technical terrain, this insert offers a noticeable increase in bottom-end power at the expense of top speed.
The insert fits perfectly with the VHM cylinder head and can be replaced quickly and easily. Each insert is marked with its unique part number for fast identification.
Use in combination with VHM head AA33182.
This insert does not fit OEM heads – VHM head required.
