The oversize letter A indicates this piston is slightly oversized to compensate for sleeve wear and ensure the correct clearance during reassembly. This product is suitable for modern 125 cc motocross bikes, including KTM 125 SX (2025), HUSQVARNA TC 125 (2025), and GAS GAS MC 125 (2025), when oversize A is required by displacement and bore.

Ideal for field mechanics and riders who want to quickly restore their engine without complex modifications. Always check the bore and piston dimensions of your cylinder before installation to ensure proper clearance and longevity of the kit.
