2025 GASGAS EX 300, Receive $750 in GasGas Parts, Garments, or Accessories good through September 2nd!

Powerful. Playful. Energetic. Yeah, our EX 300 is quite the bike! It may be a big-bore 2-stroke but it's an absolute dream to ride thanks to the electronical exhaust control helping to deliver a really usable spread of power. Short shift it and ride the wave of the torque curve or ride it hard and rail every berm in sight. The choice is yours. An updated frame for 2025 keeps things stable at speed and makes cornering even easier than ever before. It goes without saying, but our EX 300 is super versatile and an absolute blast to ride!

So much testing and development went into designing and building the frame last year, but our engineers have worked on refining things even further! Thanks to brand new, lighter, motor mounts, the flex characteristics of the frame are improved without any sacrifice to straight-line stability. Around the upper shock mount a little material has been removed while the wall thickness at the front of the frame is also slightly reduced, saving 300g. With all these revisions the bike is now much more settled through every corner.

The motor that does it all! It doesn't matter if you short shift or hang onto every gear, the revitalized EX 300 motor, with added fuel injection, separates this bike ever further from the competition with it's delivery of usable torque down low and high-revving peak power up top. And it's those who ride wide open that will benefit the most from the counter balancer shaft inside the motor as it keeps vibration to an absolute minimum. Small, light, and fast at processing data - just what you need from an engine management system! The Vitesco component is the best in the business and engages each gear's engine map, includes a rollover sensor that cuts the ignition during big crashes, and feeds information to the hour meter.
