DERBI GPR 50 RACING 50 (2005 - Present) Description & History: After the GPR 50, Derbi created the GPR 125, with a larger, two stroke engine. At first sight, the GPR 125 looks very much like the 50 GPR, but at a second glance you could notice that the 125 GPR has a longer frame, reinforced chassis, a new exhaust to improve the power of the engine and wider tires and wheels.
