2022 GasGas MC 450F Dyno Test

GasGas’ flagship motocrosser takes its first runs on the Dirt Rider dyno.

Despite the fact that GasGas’ MC 450F is the least expensive Austrian 450 motocross bike on the market at $9,999, that doesn’t mean it lacks in performance or high-quality components. The parts that differentiate it from the KTM 450 SX-F are forged triple clamps, a header pipe without a resonance chamber, lack of a map switch, softer suspension settings, silver rims, Maxxis MX-ST tires, a differently shaped fuel tank, model-specific bodywork, red seat cover, silver handlebar, and smaller handlebar pad. The MC 450F also uses the same swingarm as the Husqvarna FC 450.

GasGas shares the rest of its parts with the KTM including the chromoly steel frame, aluminum subframe, WP Xact suspension, and 450cc SOHC engine with a 12.75:1 compression ratio. Except for the header pipe, the only thing that could affect the GasGas’ power delivery compared to its orange counterpart is the airbox cover; while the 450 SX-F comes with an optional ventilated unit, the MC 450F is spec’d with just one that doesn’t have holes for additional airflow. Taking its first run on the Dirt Rider dyno this year, the 2022 GasGas MC 450F cranked out 54.0 hp at 9,600 rpm and 33.9 pound-feet of torque at 7,600 rpm. With those figures, the red Austrian ranks second in peak horsepower and third in maximum torque in the 450 motocross bike segment.
