Chain kits for motocross, enduro and trials GAS GAS: more than 10 parts from AFAM.
These parts are listed for 4 GAS GAS models; the most common are GAS GAS MCF 250 (2021-2026), GAS GAS EXF 350 (2021-2025), GAS GAS MCF 350 (2024-2025) and GAS GAS MC 250 (2026).
Chain, rear sprocket and front sprocket wear together: a stretched chain wears the teeth, and hooked teeth soon wear out a new chain. Replace the whole kit, check the pitch (420, 428 or 520 depending on engine size) and tooth count, and set the tension as per the manual.
