Vehicle Information
GAS GAS MC 150 Dirt Bike (2025)
The 2025 GASGAS MC 150 is an exciting new addition to the GASGAS motocross lineup. This model is powered by a 143.99 cm³ 1-cylinder, 2-stroke, liquid-cooled engine, featuring an electric starter and Keihin Electronic Fuel Injection (EFI) with a 39 mm throttle body. Designed to deliver increased torque compared to the MC 125, it promises dynamic performance on the track. The MC 150 is offered as a single model, without different trims. As a brand-new model for 2025, the MC 150 itself has no prior generation changes. However, the entire 2025 GASGAS motocross lineup, including the MC 150, benefits from significant chassis and component updates. These include a re-engineered chromoly steel frame for improved cornering and weight reduction, new motor mounts, an updated swingarm for enhanced chain slider durability, and revised WP XACT suspension settings. Fresh graphics with more black distinguish these models from previous years. FAQ:
