Vehicle Information
GAS GAS MC 65 Dirt Bike (2006-2026)
The GAS GAS MC 65, a dynamic youth motocross bike, has been a staple in its category from 2006 to 2026. Powered by a consistent 64.9cc two-stroke, single-cylinder, liquid-cooled engine, it offers a competitive platform for young riders. Throughout its production, the primary trim has remained the "MC 65," with occasional descriptive additions like "Cross" or "Cross Country" that do not signify distinct specification levels. While the core engine displacement remained stable, the MC 65 underwent significant evolutionary changes. Notable updates include the 2021 model, which introduced a six-speed transmission, enhanced suspension travel, larger braking components, a hydraulic clutch, and WP XACT suspension. A major overhaul occurred in 2024, bringing a new motor, bodywork, frame, transmission, and exhaust, alongside redesigned WP XACT shocks and adjustable ergonomics for varying seat heights. The 2026 model further refined the design with revisions to the triple clamps, cooling system, and front forks. Q: How can I be sure this part fits my GAS GAS MC 65?
