Motorcycle specifications DerbiGPR 125 NUDE 2005 Yeah, it does!

your thing is the roadster with a kick. When you heard that the GPR was going to 125, you wanted it without the fairing, with a mean ganache and everything you needed to have fun. Derbi thought of you and created the Nude. You take a GPR, you drop the "Racing Replica", you keep the perimeter chassis, the inverted fork, the radial brake caliper, the reinforced swingarm and the mono full of watts. But with the Nude, you're less smashed on the machine and the mill is less sharp. Zarma, why that, it's the same mill... Yes, but the exhaust doesn't have the same shape depending on the machine. But when you're out and about, you still have to push it into the turn. The Nude is like the GPR, only the face changes.
Once the bridle has been removed (it's forbidden except for track use), the mill produces 22 hp, enough to make a serious difference. Not enough power? An exhaust kit and you've got 30 hp on the crankshaft. Enough to take on a Cagiva Mito or an Aprilia RS.

in that case, you can only ride the GPR on the track. There's no question of dragging your feet in the mid-range, you've got to get the power from the revs. The mono engine is at its best between 8,000 and 10,500 rpm. Staying within this narrow range is essential. Playing with the gearbox without restraint, making the 2-stroke howl, drawing beautiful trajectories, the little Spanish bike demands a lot of driving. An excellent school for the sport, which makes you hate the original tires all the more. They may be renowned Italian tires, but they come from a soap factory. A lack of rigor that makes the front brake die laughing. Don't worry about it; it's superbly efficient. On a leisurely ride, you'll quickly get fed up with the Spartan comfort, the lousy turning radius, the side stand that comes back on its own and the clumsy tires. And I'm not even talking about the price..."
If you've always got an itchy right hand, you've got no choice but to whinneezz!
