Vehicle Information
GAS GAS MC 85 Dirt Bike (2021-2026)
The GAS GAS MC 85 is a motocross bike designed for youth riders, covering model years 2021 to 2026. It is powered by a robust 84.9 cc, 1-cylinder, 2-stroke, liquid-cooled engine. This model is primarily offered in two wheel size configurations: the MC 85 17/14 (17-inch front wheel, 14-inch rear wheel) for smaller or transitioning riders, and the MC 85 19/16 (19-inch front wheel, 16-inch rear wheel) for taller or more experienced youth riders. While core engine specifications remained consistent from 2021 to 2024, the MC 85 underwent a significant overhaul for the 2025 model year, with these enhancements carrying over to 2026 models. This update introduced an all-new frame with reworked geometry, an updated WP XACT shock, and engine revisions focused on boosting low to mid-range power and torque. The bodywork was also redesigned for improved ergonomics, and a lighter swingarm was integrated, marking a new generation for this model. Q: How can I ensure parts fit my GAS GAS MC 85?
