GRAPHICS

All-new graphics spice things up for 2025 with the GASGAS logo emblazoned in black rather than white for a fresh twist. Still red, still durable, and still eye-catching, the distinctive design is applied using IML technology. This means they're applied within the bodywork so your GASGAS will stay looking super fresh for a long, long time, even if you ride in gnarly conditions week after week.

FRAME

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, which were tested by Red Bull GASGAS Factory Racing in MXGP, the bike is now much more settled through every corner.

ELECTRONIC FUEL INJECTION (EFI)

For 2025, our 2-stroke motors are fuelled using Throttle Body Injection - a 39mm Keihin throttle body, to be precise - which works together with the Engine Contol Unit (ECU) to deliver the perfect mix of fuel and air. The end result? Crisp, clean running motors that create smooth, strong power.

HYDRAULIC BRAKES

Fast is fun but slowing down is essential, which is why all GASGAS dirt bikes are fitted with high quality Braktec calipers and controls. Speaking of controls, the rear brake pedal is now considerably stronger to prevent it from getting bent out of shape in a crash or catching the ground when you're railing through a deep rut. When you combine those Braktec calipers with GASGAS specific brake disks, 260mm up front and 220mm at the rear, the end result is amazing braking performance. This all means that all riders can stay on the gas longer and brake later into corners. And we all know what that leads to... faster lap times!

ENGINE MANAGEMENT SYSTEM (EMS)

Small, light, and fast at processing data - just what you need from an engine management system! The Vitesco Technologies component is the best in the business and includes a rollover sensor that cuts the ignition during big crashes, as well as feeding information to the hour meter.
