2021 GasGas Motocross Lineup First Look (Specs and Photos)

When under Spanish ownership, GasGas was never known as a motocross brand. However, under the guidance of Pierer Mobility AG and Bajaj Auto—the owners of KTM—that’s about to change. There will be three GasGas motocross bikes for 2021—a 125cc two-stroke, plus 250cc and 450cc four-strokes.

As far as we can tell, the GasGas MC models are the same as their KTM counterparts, with one significant exception. The GasGas MC MX racers will have Maxxis Maxxcross MX-ST tires, rather than Dunlop Geomax MX33 rubber.

Given that, we will refer you to our 2021 KTM Motocross and Supercross Lineup First Look story for technical details. In the meantime, we have the specs on the 2021 GasGas Motocross lineup, along with photos of the motorcycles featuring red plastic.

GasGas will have a significant presence in supercross and motocross in 2021. The Troy Lee Designs Red Bull Gas Gas Factory Team will be putting the brand at the starting gate. So far, there are no confirmed riders for the team, though Justin Barcia has been repeatedly rumored to be part of the 2021 GasGas supercross and motocross effort.
