1976 Derbi Grand Prix 2002 Deportiva Atlas Editions Classic Motorcycle Card
A tradition of two·stroke twins
After three years of using engines from outside suppliers (IRESA and Hispano-Villiers) or built under Jawa license, Derbi put its first machine with an “in-house” engine on the market in 1953. This was the Type 95 two-stroke twin, and Derbi used this layout twice – the third generation was known as the 2002 GP.
Spanish “Twingle”
Launched at the Barcelona International Fair in 1952, the first prototype twin underwent another year of development before being put on the market with a displacement of 98cc and a layout like the Puch, with a common combustion chamber for two cylinders. Produced in large numbers, the Type 95 earned a fine reputation for reliability and longevity.
Too Expensive
The second Derbi twin was unveiled five years later, again at the Barcelona Fair. This was a classic 350 with two cylinders and two separate cylinder heads; it could touch 75 mph on its 16 hp output. Handicapped by its high price, this 350 only achieved limited sales. The third generation of Derbi twins was another 17 years arriving. It was not until 1974 that the first 2002 GP made its debut – initially as a 187.5cc bike with drum brakes. Two years later, it was available in three versions. The Economica was unchanged, but there were also the Deportiva (“Sporty”) and GT, with the displacement increased for more power and low speed flexibility. The Deportiva and GT shared triple disc brakes, but had different gearing and different lubrication systems, and the GT had electric-start and more efficient mufflers.
