2024.5 GasGas MC450 Factory Edition Turbo – Built by Mr. Turbo Himself!
Feast your eyes on the most outrageous 450 Factory Edition ever built. This is a brand-new 2024.5 GasGas MC450 Factory Edition that’s been transformed by Mr. Turbo himself, into a 93-horsepower monster. Yes, you read that right—93 horsepower. .
This GasGas is an entirely different animal.
🔥 Brand-New Turbocharged Factory Edition
Straight from Kaplan Cycles, the #1 GasGas dealership in North America, this was taken right off the showroom floor and immediately sent to the shop to build. Every part of this bike was carefully engineered for boost — a fully developed, purpose-built system designed for reliability and sheer power.
When you fire it up, the turbo sings before you even let the clutch out. Crack the throttle and it howls like nothing else on Earth. On boost, it’s like riding a lightning bolt—controllable, yet violently fast. You can feel the turbo spool, hear it hiss, and watch bystanders’ jaws drop.
The bike is in brand-new condition. The rear tire still had the nubs before its first wheelie test run up the driveway. .
⚙️ Hand-Built by “Mr. Turbo” — Engineered for Boost
Justin “Mr. Turbo” Harris is a legend in the turbocharging world, and this isn’t his first rodeo.
He’s built dozens of specialty turbo bikes, including the matching GasGas 700 Supermoto seen in our video lineup.
Key engine mods include:
-
Lowered compression ratio for safe, reliable boost
-
ARP cylinder studs for maximum clamping strength
-
Oiling modifications for improved lubrication under boost
-
Shimmed intake valve springs to prevent float under high pressure
-
Aluminum-welded custom airbox tuned for OEM harmonics and smooth airflow
Hundreds of hours of R&D and build time went into this machine. Justin even attended KTM Group’s engine school in Ohio, collaborating with factory engineers to spec the engine hardware identical to that used in their pro-race motors.
This setup is pump-gas friendly (93 octane), fully tuned on a Dynojet Power Commander, and runs the stock fuel system. No exotic fuel, no drama—just proven, bulletproof performance.
