Insert KTM 65SX 2024 – 2026 / Husqvarna TC65 2024 – 2026 / GasGas MC65 2024 – 2026 (5.55cc) VHM for 12° piston

The AE32353-012 VHM insert features a higher volume and lower compression ratio than the standard VHM insert, delivering enhanced overrevolution characteristics and improved top speed. This makes it an excellent option for hard ground or enduro-style tracks, where maintaining speed at higher RPMs is essential.

It is compatible only with the VHM 12° piston (APKT06521722) and VHM cylinder head (AA33217). The correct gasket configuration is OEM 0.70mm base gasket—no additional spacers are required.

This insert is part of VHM’s swappable head system, making setup changes fast and easy. For best results, refer to the insert chart when choosing the correct insert based on track type, fuel quality, and altitude.

Not compatible with OEM heads.

Insert code is engraved on the component for accurate identification.

• Greater top-end power
