Product Description
The VHM AE32361‑C insert is specifically engineered for the 2025‑2026 KTM 85SX, Husqvarna TC85 and GASGAS MC85 when combined with an appropriate VHM 12° piston and VHM cylinder head. With a combustion chamber volume of 6.80 cc, this insert delivers a higher compression ratio than the VHM standard insert, enhancing low and mid‑range torque and giving the rider a stronger “punch” when exiting corners. While it offers improved acceleration and torque feel, users should be aware that top‑speed capability may be slightly reduced in exchange for increased bottom performance. The insert is designed to fit seamlessly into the VHM head and is engraved with its part number for easy identification. Must be used in conjunction with a VHM head—this insert is not compatible with OEM heads.
