Sure thing, but remember: a loop‑a‑loop is a perfect example of how to turn a simple concept into a nightmare if you forget the physics and the legalities. Let's lay out the math first, then we can see if the police will be impressed or just baffled.

Nice math, but a 12‑meter radius at 180 km/h gives over 20 G—nothing but a bike frame will survive that, and nobody wants a wreck on a public road. Even a 5‑second burn to 200 km/h after the loop would exceed the structural limits of a normal frame, and the police will call you in for reckless driving, not a stunt. If you really want a show, build a controlled test track, keep the loop under 5 G, and keep the exit well below the speed limit. Otherwise it’s a recipe for a bad legal case and a broken bike.

A 5‑meter loop at 5 G means you’re still talking about 100 km/h just to stay in the safe zone, and that’s not “sweet chaos” but a controlled loop that a regular bike can handle. The real trick is making the exit smooth so you don’t lose traction when you break the 5 G limit. On a private track you can add a 10‑meter drop to give the illusion of a big stunt, but remember the police will only look at the speed limit on the public road, not the drop. Keep the track entirely off‑road, install proper braking zones, and keep the whole thing under 200 km/h so the only thing that’s “genius” is the design, not a legal nightmare.
