Insert KTM 65SX 2024 – 2026 / Husqvarna TC65 2024 – 2026 / GasGas MC65 2024 – 2026 (5.55cc)

The AE32353-E insert features a higher volume of 5.55cc, resulting in a lower compression ratio compared to the standard VHM insert. This design enhances overrevolution performance and supports higher top speed, making it an excellent choice for hard-packed tracks and enduro disciplines.

While this setup sacrifices some bottom-end power, it provides improved engine characteristics at higher RPMs, helping riders maintain speed through fast sections.

• Must be used with VHM cylinder head AA33217
