2026 GasGas MC 450F Factory Edition Rockstar

Our well-loved MC 450F Factory Edition has received a tasty makeover for 2025! Besides the new and super cool Rockstar Energy graphics that our AMA Supercross and Pro Motocross team will run, there are a few notable, and spicy, changes too. You’ll now find an FMF Factory 4.1 RCT silencer, Factory Racing Wheel Set, and ProTaper handlebars. All of which will be used on the race bike of Justin Barcia as he embarks on his fifth season with GASGAS. The Connectivity Unit and GPS sensor is retained from 2024 as the tech is just so good! Once they’re both linked up to your smartphone you can create, save, and activate various engine maps as well as being able to record your lap times and see the fastest way around any race track. Trust us, the 2025 MC 450F Factory Edition is an incredible dirt bike…
