The Derbi GPR125 is arguably one of the most beautifully styled 125 motorcycles ever made. On a murky day you might mistake it for a baby Ducati or MV Agusta motorcycle. The Derbi GPR125 also goes very well (de-restricted of course ) and handles just like a racing motorcycle, with firm suspension and a substantial 300mm front disc brake. The Derbi GPR125 is a teenage dream on wheels.

Obviously this motorcycle was designed to have some Pepperami stick man on board, but even so, the Derbi GPR125's handling is road racing motorcycle precise, with  a twin beam alloy frame, box section braced swingarm and supsension developed from the Derbi 125 Grand Prix racers. Any young rider with skill can ride the Derbi GPR125 very, very quickly around roundabouts, making lardbucket Grandads on motorcycles like the Yamaha R1 look pretty lacklustre.

The Derbi GPR125 is a two stroke motorcycle, which is a big plus point for any younger rider, as four stroke 125cc motorcycles generally sound - and often go - like Aunty Mary's sewing machine. The Derbi GPR125 makes a claimed 33bhp, which is about the same as the Aprilia RS125 and there's a 6 speed gearbox to make the most of it. This motorcycle should be good for about 90mph on the way to Pizza Hut.

Since Piaggio Group took control of Derbi the overall build quality of it's motorcycles has definitely improved and the post 2005 built motorcycles look like a different generation from the older Derbi GPR50 series. The spares situation should be better too. There's no doubt that the Derbi GPR124 will get a hard life from the average teenage motorcycle owner however, so choose a used Derbi GPR125 carefully.

The Derbi GPR125 is undeniably expensive, but you do get a great deal of race motorcycle styling, and racetrack ability, for your money. Like the Aprilia RS125, the Derbi GPR125 is beyond the reach of most 17 year old's budgets ( or their parents' chequebooks ) but that won't stop peope wanting one when they see the Derbi GPR125. Derbi GPR125 Nude looks a poor value motorcycle at just a hundred quid less than the GPR125. Find a Derbi GPR125 for sale.


5 out of 5 (5/5)

The Derbi GPR125 looks the absolute dogs whatsits, from the mirror/indicators at the front, to the underseat exhausts poking from the motorcycle's bodywork at the back. Big brakes, wide 17 inch wheels, radial brake caliper - the Derbi GPR125 has got pretty much all the kit you'd expect on a 125cc class sports motorcycle

Yamaha tzr engine, literally the only part if the bike parts are easy to get for. Works well plenty of power, easy to derestrict.7.5amp fuse under the seat instant 33bhp.

4 out of 5 good alternative to the rs125
23 March 2008 by liquid_metal

Take 1 rs125, take away a little bit of performance add a lot of reliabilty and your left with the GPR125. Good looks, slightly cheaper to buy but a lot cheaper to run then the rs125. its well worth the small loss of acceleration and top end. (would still run rings around the cbr 125 though)
