Picture this: you stroll out of your house on a sunny Saturday morning, throw a leg over your MotoGP bike, and blast off to grab a cup of coffee. Not a replica, not a sportbike pretending to be something more, but an honest-to-goodness GP machine, the kind you see the world's fastest racers wringing out at 200 miles per hour on a Sunday.
It’s the ultimate fantasy for any rider. The problem? That dream is about as attainable as owning a Formula 1 car. MotoGP bikes are multi-million dollar prototypes, tuned for aliens on two wheels, and about as friendly to daily use as a chainsaw in rush hour traffic.
So what do you do when reality crushes your MotoGP dream? If you’re YouTuber JBellz, you make your own.
JBellz has built a reputation online as the kind of DIY guy who doesn’t just talk about big ideas—he actually builds them. CAD software, 3D printing, custom fabrication, you name it, he’s got it in his arsenal. His latest project is his boldest yet: transforming a 2024 KTM 1390 Super Duke R, one of the most insane naked bikes on the market, into a MotoGP-inspired monster.
The wild part is that the 2024 KTM 1390 Super Duke R doesn’t even need the MotoGP treatment to be borderline unhinged. It’s already packing a monster 1,350cc V-twin with around 190 horsepower, a lightweight chassis dripping in high-spec components, and enough electronic wizardry to keep most riders in one piece. Snap the throttle in pretty much any gear and the front wheel will happily pop up to the sky. This is the foundation JBellz decided wasn’t quite crazy enough.
He wanted something that looked like it came straight from the KTM factory racing garage. So he designed his own tank and tail section in CAD, pulling cues directly from the 2024 RC16—KTM’s MotoGP machine. Those designs turned into rough, low-poly 3D-printed panels, mocked up on the bike to nail the fit and silhouette before committing to the real deal in either carbon or fiberglass.
But this wasn’t as simple as peeling off some plastics and slapping on new ones. Naked bikes might look like they’re already stripped down, but once you start pulling at structural pieces and working around modern electronics, things get intimidating fast. Still, JBellz dove in, disassembling the Super Duke and carefully reworking it until the new bodywork sat just right.
The prototype is already giving off serious GP vibes. Long, low, aggressive, and unmistakably RC16 in its stance, yet built on a platform that’s actually rideable on the street. It’s a race bike dream filtered through real-world usability. The next step is where the artistry really kicks in: smoothing out those 3D-printed panels, shaping the bodywork, and finishing it in paint worthy of a MotoGP pit garage.
That’s the magic here. 3D printing and CAD haven’t made custom building “easy,” but they’ve made it possible. With enough skill, time, and guts, someone like JBellz, or perhaps even you and me, can bring the MotoGP fantasy into the real world—not by buying one, but by building one. And that’s about as badass as it gets.
