2026 GasGas MC 450F Technical Overview

Features and specifications of GasGas’ 450cc motocross bike for 2026.

Updated: December 26, 2025

The most affordable 450cc motocross bike from Austria is GasGas’ MC 450F. The brand is able to price its flagship MX model lower than its model-equivalent cousins (KTM’s 450 SX-F and Husqvarna’s FC 450) through use of lower-spec components such as forged triple clamps, Braktec hydraulic clutch and brakes, and Maxxis Maxxcross MX-ST tires. Such items help GasGas offer its MC 450F for $10,499, which is $900 and $1150 less than the FC 450 and 450 SX-F, respectively.

Prior to getting the MC 450F dirty for our 2026 450 Motocross Bike Comparison Test, we pointed our cameras at it to bring you this technical overview article—showing component differences from its Austrian relatives and offering information about it in general.

Its fuel-injected liquid-cooled SOHC four-stroke 450cc single-cylinder engine makes 53.4 hp and 34.2 lb.-ft. of torque on the Dirt Rider dyno.Jeff Allen

A header pipe without resonance chamber and longer muffler with smaller opening are a few exhaust-related differences between the MC 450F and its model-equivalent Austrian cousins, KTM’s 450 SX-F and Husqvarna’s FC 450.Jeff Allen

GasGas is the only brand to spec a Braktec hydraulic clutch on its 450cc motocross bike.Jeff Allen

Without an engine map, traction control, launch control, quick-shift module, the only buttons on the MC 450F’s handlebar are engine start and stop.Jeff Allen

Cutouts in the frame’s shock tower and head stays were first seen on the MC 450F Factory Edition in 2024 and MC 450F the following year.Jeff Allen

The MC 450F relied on a 42 Nm shock spring from 2021–2023 and switched to a 45 Nm in 2024, matching the 450 SX-F and FC 450.Jeff Allen

Black rims are a new look for GasGas’ full-size motocross bikes in 2026.Jeff Allen

The MC 450F is unique among the Austrian trio in its use of Maxxis Maxxcross MX-ST tires. It shares the same gearing as the 450 SX-F and FC 450 with 13-tooth countershaft and 51-tooth rear sprocket sizes.Jeff Allen

While all other 450cc motocross bikes use Brembo or Nissin brakes, GasGas specs its with Braktec.Jeff Allen

In addition to switching handlebar and rim color from silver to black, GasGas completed its MY26 full-size motocross bike appearance with new radiator shroud graphics that sport a small brand logo (and motto), unlike previous years where font was much larger and spread across the entire sides of the bodywork.Jeff Allen
