Exchangeable combustion chamber (insert) for the VHM cylinder head AA33217. Chamber volume 5.40 cc. 🔴 The insert fits ONLY the VHM head AA33217 — it cannot be fitted into the OEM head. For the stock (OEM) piston. This is the VHM standard insert for this head — the default choice if you are not sure which one to pick. Quick to change — the insert simply sits in the head and seals with O-rings. The last characters of the part number are engraved on the insert, so you cannot mix them up. The manufacturer's chart in the photos shows the choice by fuel, track type and elevation. Use it as a starting point. Fits: Husqvarna TC 65 (2024–2027); KTM 65 SX (2024–2027); GasGas MC 65 (2024–2027).
