Vehicle Information
GAS GAS MC 250 Dirt Bike (1995-2026)
The GAS GAS MC 250 is an iconic motocross motorcycle, produced from 1995 to 2026. This series includes both two-stroke (MC 250) and four-stroke (MC 250F) models, each designed to deliver optimal track performance. Renowned for its handling and power, the MC 250 has evolved over the years to meet the demands of riders. The two-stroke MC 250 model primarily used a carburetor (Keihin PWK or Mikuni TMX 38) and a 6-speed transmission until 2023. A significant update in 2024 introduced electronic fuel injection (EFI) and a 5-speed gearbox. The four-stroke MC 250F, launched in 2021, underwent a major overhaul in 2024, including engine and chassis updates, with Factory Editions offering high-performance components. 2025 and 2026 brought further chassis refinements and aesthetic adjustments for both models. Q : How do I know if this part fits my GAS GAS MC 250?
