Insert KTM 250SX 2023 – 2026 / Husqvarna TC250 2023 – 2026 / GasGas MC250 2024 – 2026 (22.60cc) Fuel 98 RON

The AE32337-F VHM insert, with a 22.60cc combustion chamber, offers a lower compression ratio, which results in smoother overrev performance and increased top speed. This makes it particularly effective on hard ground or fast-flowing tracks where maintaining momentum is key.

It is specifically engineered to fit the VHM cylinder head AA33209, and the insert is easily swappable for quick setup changes depending on race conditions. The part number’s final digits are engraved on the insert for easy identification.

Fuel requirement: Use 98 RON octane fuel for optimal detonation resistance and performance.
