Vehicle Information
GAS GAS MC 125 Dirt Bike (1995-2026)
The GASGAS MC 125, a high-performance 125cc two-stroke motocross motorcycle, has been a staple in its category from 1995 to 2026. Throughout its history, it has consistently featured a 124.8cc liquid-cooled, single-cylinder engine. A significant transformation occurred in 2019 with the acquisition of GasGas by Pierer Mobility. This led to the modern MC 125 (from 2021 onwards) sharing its platform with the KTM 125SX, offering a refined yet competitive package. While earlier models (1995-2020) had their own distinct characteristics, detailed information is less available. The 2021-2024 models maintained a carbureted engine. A major engine evolution arrived in 2025-2026 with the introduction of Electronic Fuel Injection (EFI) and a Keihin throttle body, replacing the carburetor for smoother power delivery and improved efficiency. These later models also feature updated chassis components and visual enhancements. The MC 125 is typically offered as a single model, with yearly updates rather than distinct trim levels. FAQ:
