Cylinder Head – Suzuki RM250 (2001‑2008)

The VHM AA33038 cylinder head is designed for the Suzuki RM250 across model years 2001 to 2008. Manufactured from a premium aluminium alloy, this head features an improved water duct layout and uses O‑ring sealing for superior reliability. Its key feature is the exchangeable combustion chamber insert system, which allows quick replacement to adjust compression ratio or suit different fuels and track conditions. This flexibility makes it ideal for competition and tuning applications where adaptability and performance are paramount. The head body must be used in combination with VHM standard insert options (e.g., AE32053‑E for 2001‑02 and AE32053‑H for 2003‑08) to complete the unit. Overall, the AA33038 provides higher engine output, better heat dissipation, and increased resistance to detonation.
