2025 GASGAS MC 85 17/14, Looking just like our full-size motocross bikes, the MC 85 is finished with the same style graphics. Applied to the all-red, ergonomic bodywork using in-mould technology, they'll never fade, peel, or scratch. So, this little ripper will look legit for quite some time. Topping off the look is the full gripper seat cover (in red, of course!) that features a unique texture for maximum grip for when you're either sat down and hard on the gas or up on the pegs and attacking the track.

Knowing how good the frames are on the full-size GASGAS motocross bikes, our clever engineers set about transferring all the good stuff over to the new steel frame on the MC 85. We're talking straight-line stability, agility in the corners, and just the right amount of flex for maximum comfort. And it's safe to say that the end result is a huge step forward from the outgoing bike. Even the red frame protectors are new. Instead of a smooth finish, they now have a textured surface to help kids grip the bike better with their legs, which in turn helps to reduce fatigue.

Hang with us, there's a lot going on with the MC 85 motor for 2025! It may look familiar, but there are plenty of important revisions that really change how this little ripper performs on track. Together, a new cylinder head, spark plug, and ignition boost power and torque in the low to mid-range while updated jetting settings and a new exhaust make sure the bike still sings when up high in the rev range. The motor is now positioned in the frame a little differently as it's rotated backwards three degrees from the same mounting point at the swingarm. That might not sound a lot, but this really helps distribute the weight of the motor to balance the bike out and creates a much more engaging ride. Finally, thanks in large part to the new components and a revised manufacturing process, the motor is 120g lighter than the old generation.
