Post-Sale Update: This Derbi GPR 50 Nude did not get any takers despite a lowered BIN price of $1,999.
Derbi is a small Spanish company that started as a little bicycle shop near Barcelona, Spain. In fact, the name Derbi itself refers to the company’s beginnings, as it’s an acroynm (in Spanish) for “Derivatives of Bicycles). Derbi ended up being the only major Spanish manufacturer to survive the country’s transition to democracy, and they plugged along until 2001 when they were bought by Piaggio. 
Derbi has always been excellent with their small displacement bikes, and the GPR 50 is no different. Mixing the cosmetics up a bit, the Derbi GPR 50 Nude loses some front fairings to create a naked bike that looks a lot more aggressive than 49cc might be able to justify! With that said, this Derbi is full of ‘big-bike’ features. The two-stroke engine is water-cooled, and you’ll get a 6 speed transmission. You’ll get almost 100 miles per gallon while the 8 horsepower engine pushes you around town. Just remember – some of these were restricted to a top speed of 30mph. Pulling the restrictor off will let you double that speed, at least. 
This specific Derbi GPR 50 Nude has just 65 miles. It’s never been registered, and as you’d expect, it’s in great shape. We’d love to see it lined up with a Triumph Speed Triple from the front – it looks like a baby Striple. Unfortunately, parts support in the US is nearly non-existent. You’ll be going to the UK or Continental Europe for help.
