With Phil Aynsley


The mid to late 1970s was a turbulent period for the Spanish motorcycle industry. Bultaco, Mototrans and Ossa closed their doors while Montesa was taken over by Honda and Sanglas by Yamaha. Which left Derbi as pretty much the sole survivor of the major brands to remain in original hands.

Perhaps one contributing factor for this was the company’s desire to keep at the front of current technology. This 1976 2.002 GP 6V is a good example. The 2.002 referred to the ‘200 cc’ capacity and two-cylinders, at a time when single-cylinder motors were the norm.

It was the most advanced bike produced in Spain at the time and used a 187 cc 2-stroke parallel-twin motor that originally had a five-speed gearbox that was quickly changed to a six-speed. Other features included a digital gear indicator and a twin leading shoe front brake.

Later versions had a single disc at the rear and twin discs at the front. The engine capacity was also increased to 199 cc which resulted in output rising from 23 hp at 7600 rpm to 27 hp at 8600rpm. Weight of the 2.002 models was around 125 kg, depending on the version.

The last version of the 2.002 was the 250T of 1978. Apart from the capacity and power increases the 2.002 name was dropped.

A look into some rare Derbi 125 cc Grand Prix machines

Derbi 125 cc GP Racers

I’m afraid information about these bikes is scant, but as they are such interesting machines I’ll have have to let the photos tell the story. Firstly we have (an extremely rare) example of Derbi’s first 125 cc GP design.

Derbi’s first 125 cc GP design

Race team chief and engineer Francisco Tombas (also responsible for the highly successful 50 cc GP) introduced this narrow-angle, air-cooled V-twin in 1967 and it competed until the completely new water-cooled twin replaced it in 1970.

The twin crankshaft design was basically two singles mounted one above the other with a common crankcase. An six- to eight-speed gearbox was used, depending on the circuit. Two 24 mm Dell’Orto carburettors were fitted.

By 1969 the output was 32 hp at 13,500 rpm and the 100 kg machine was good for a top speed of 215 km/h. The bike was not particularly successful however with only a single top-six placing in GPs. While Angel Nieto did not compete in the 125 GP class prior to 1970 he apparently raced this bike in the Spanish Championship in ‘69.

Secondly we have the only surviving example of the two Derbi 125cc water-cooled twins built for Angel Nieto for the 1970 GP season. He finished 2nd in the championship to Dieter Braun on a Suzuki with both winning four races each. It was later raced by Benjamin Grau in the Spanish Championship.
