New 2026 GasGas Off-Roaders Specs

Cycle News Staff | August 31, 2025

The 2026 GasGas motocross and off-road models, including cross-country and enduro, feature a new distinctive look. They get a few technical mods as well, but it’s their updated looks that take precedence.

When it comes to the 2026 GasGas motocross (MC 250 models pictured) and off-road model, the big news is—black rims!

Most notable across the 2026 line are black anodized Excel rims, replacing the old-school silver ones. Red seat covers are swapped out for a full-black gripper seat, with Neken handlebars and bar pads also in black, highlighting the styling updates. And of course, the bikes feature fresh graphics.

Besides the aesthetic updates, all bikes now have updated fuel-line protection caps that are said to improve durability and prevent dirt from entering the connector. All the 2026 two-strokes feature rerouted wiring harnesses for better reliability, with all enduro models now coming with a radiator fan.

2026 GasGas EX 300 cross country
The EX 300 two-stroke is GasGas’ only cross-country model for 2026.

The 2026 MC 50, MC 65 and MC 85 (which is available in two wheel-size options) feature several technical updates as well, including revisions to the triple clamps and cooling system. Plus, the MC 50 and MC 65 are now equipped with improved forks for a plusher feel.

All motocross models return for 2026. There will be two enduro models, the two-stroke EC 300 and four-stroke EC 350F. The only cross-country model for 2026 will be the EX 300 two-stroke.

Availability and pricing have not been announced. CN

Technical Highlights – Motocross

  • WP Xact front fork with AER technology – Features a hydrostop to take the sting out of heavy landings with all settings easily adjustable by hand.
  • WP Xact rear shock – By offering 300mm of travel, the WP Xact shock delivers comfort and performance.
  • Throttle Body Injection with premix for two-strokes – Making sure our MC 125 and MC 250 run clean and crisp at all times for maximum power and torque.
  • Tires – Both wheels are wrapped in Maxxis MX-ST tires for the best grip possible on every type of terrain.

Technical Highlights – Cross country

  •  Pankl transmission – Assembled with 6-speeds and ratios designed for wide open, cross-country-style riding.
  • WP Xact closed-cartridge front fork – Assembled with steel springs, a pressurized oil chamber, and a hydrostop that takes the sting out of heavy landings. And they’re easily adjusted by hand, too.
  • Larger fuel tank – Taken from our enduro bikes, you can fill the EX 300 up and enjoy extended ride times before refueling thanks to the 2.37-gallon fuel tank.
  • 18” rear wheel – Another thing taken from our enduro models, the 18-inch rear wheel helps to put more rubber on the ground for maximum traction. The rear tire is a Dunlop Geomax AT82 110/100-18 and up front you’ll find the same tire, but the size is 80/100-21.

Technical Highlights – Enduro

  •  WP Xplor front fork with open cartridge – In addition to being easily adjustable by hand, the forks deliver consistent performance and soak up every bump with ease. New settings for 2026 deliver improved performance on each individual model, with the forks continuing to offer full adjustability by hand.
  • WP Xact rear shock and linkage – Inside, the piston is designed to ensure maximum rider comfort and with updated settings for 2026, the progressive performance of the WP shock is refined even further.
  • Dunlop Geomax AT82 tires – A new tire compound for 2026 provides maximum traction from your very first ride!
