There was a time when the legendary Spanish riders such as Angel Nieto and Jorge Martinez dominated the 80cc category in the MotoGP riding their red-coloured Derbi.

To homage them and their bikes with their characteristic noise, the Spanish trainer Pepo Rosell, in 2016, decided to build a cafe racer that would appeal to the 80 cc class racing bikes.

As a basis, a 1987 Derbi FDX50 was used, and the only original components left unchanged were the braking system and the fork, although the latter was however slightly lengthened.

Everything has been modified starting with the rear axle, and later adapted to accommodate a pair of artisan shock absorbers instead of the original mono.

The front part of the frame has also been revised for functional reasons, with the 50 cc engine being replaced with a higher performance unit. Although thew new motorbike presented a Euro 3 engine, it was always two-stroke liquid-cooled; only re-engineered to reach a volume of 80 cc and equipped with new 24O OKO carburettor. Furthermore, just like on real racing bikes, a Selettra internal rotor ignition was installed.

Rosell himself followed the entire process design and he included not only the aerodynamic hull in plexiglass of a racing Derbi RAN but also the front fender, the tank and the handmade rear seat.

Tested on the track, it could reach 158 km/h, confirming the solid resuls of the entire project.
