GASGAS MC 85 17/14 2026

Next-level offroad enjoyment

RRP: £6,199.00
  • Together with our global team of talented, young test riders, we've developed what can only be described as an incredible 2-stroke motocross bike! From the new frame and WP shock to the improved motor and redesigned bodywork, just about everything is new, making for a seriously fresh MC 85 in 2025. As well as the increased performance, the riding experience is considerably improved too. Slimmer ergonomics and a handlebar bend created specifically for younger racers inspires confidence and makes laps at the track so much more enjoyable. The end result of all the changes is a bike that delivers incredible performance and rideability for such a small motorcycle. And if there's one thing that we can guarantee, it's that kids will absolutely love it!
