Overview[edit | edit source]
Derbi GPR 125 Nude
In the image and style of its cousin, the GPR Racing, Derbi has created the
Nude 50 & 125. For design, quality and performance the 'Naked' version meets the
requirements of even the most demanding riders.
Having the appearance of a larger capacity motorcycle and with cutting edge
technology already witnessed in the Racing version, this model is certainly an
attention grabber. The form and lines of the Nude transmits a great sensation of
liberty, with its engine and innards on show. A carefully crafted front end has
replaced the fairing of the GPR with double optical headlight crowned by a small
screen bubble. The result is very striking and not surprisingly it was decreed
the winner of 'Best Open Design' at the last Paris show, a prize awarded by the
MDA (Motorcycle Design Association), defeating bigger and more costly
motorcycles.
However aside from just the aesthetics, the reason for the new Nude resides
in the engine. It is powered by a potent 50cc or 125cc two-stroke unit, quiet,
reliable, with good performance and smooth driveability. It is also perfectly
adapted to the low levels of emission required by the Euro 2 law. Open the 'gas'
and note how the two-stroke engine is accompanied by a seductive growl that
rumbles forth from the exhaust. Thanks to the Nude you will not have to search
superior categories to enjoy advanced naked
