Derbi GPR is the most hi-tech model in this bike category, offering technical solutions only available on sports bikes with a higher engine capacity.
DERBI GPR 50 2 STROKE and 125 4 STROKE.
Derbi GPR, the young heir to the legendary “Balas Rojas”, stands out among the small sports bikes thanks to its unique features. Now the brand new 125 4 stroke engine is accompanied by the renewed 50cc version, dedicated to the youngest fans whose first approach to the biking world is the search for a state-of-the-art object.
In the 125 and 50cc engine capacity versions, Derbi GPR was created from the sports experience of the Moto GP 125 which saw Mike di Meglio become 2008 World Champion, and which has kept on winning also in the current season, with the young Pol Espargaró(Derbi Racing Team).
After completing its of 125cc engine range, Derbi is now enhancing its selection of bikes driven by the most technologically advanced and competitive engines of smaller sizes. Derbi amazes yet again, thrilling the younger clientele with a 50cc engine on the new GPR - the most sporting bike of the illustrious Spanish marque.
Directly derived from its elder sibling fitted with the 125 4 stroke engine, the new smaller model Derbi GPR 50cc 2 stroke boasts a series of features and merits that are really exceptional for bikes of this category: the dual beam chassis in die-cast aluminium offers great sturdiness, while at the same time maintaining the pure forms. The front suspension is also of an extremely high level, with its robust upside down 41mm fork with red anodised stanchion holders and a stroke of 110 mm, while at the rear there is an Ollé single shock absorber system directly fixed to the swingarm. The braking system is tops: at the front a powerful 300 mm disc with four pistons and radial fixing, backed up by a 220 mm rear disc on the 125cc version, and a 218 mm one on the 50cc version (both with a single piston calliper).
In both the 125 4 stroke version and the new 50 2 stroke, Derbi GPR mirrors the racing spirit of the legendary "Balas Rojas", the Derbi sports bikes that conquered a good 19 world championships over their history (11 riders' titles and 8 manufacturers' titles).
The fairing highlights the flowing, stylised lines that emerge from the aggressive and sharp front also thanks to a powerful double headlamp (with LED position lights), spreading over the tank/saddle area to create a sense of continuity with the fairing, and then terminating in the sharp, raised tail fairing including the passenger seat with footrest and a rear LED light. The design of the 12-spoke rims, measuring 17” on both front and rear for both GPR engine sizes (all burnished), further strengthens the sporting character of this bike.
In the 125cc version, yet another detail emphasises the highly refined level of the Derbi GPR: the exhaust system, strongly inspired by the Grand Prix bikes and fully integrated in the lower part of the fairing. A solution that's not only attractive from the design point of view, but also exerts a strong influence on dynamic behaviour, thanks to an additional reduction of the bike's centre of gravity.
With the new GPR 50 2 stroke and 125 4 stroke models, Derbi confirms itself as the world leader with regards to its range of young, sporty bikes with small engines, offering vehicles that exceed the expectations of even the most demanding riders.
A refined chassis architecture like that of GPR can't fail to be linked to the very latest engines.
The 50cc single cylinder of the Piaggio Group is a liquid-cooled two-stroke characterised by reed intake. The lubrication uses a separate mixing system with a variable capacity volumetric pump. The 6-speed gearbox allows you to take the best advantage of the top engine performance levels.
This small but snappy engine, created for Derbi GPR, joins the powerful and well-known 125cc 4 stroke 4-valve single cylinder developed by Piaggio and Derbi: a state-of-the-art engine of the latest generation that's already sparked a real revolution in this engine size category.
The Derbi GPR 125 4 stroke has a maximum power of 15 CV at 9,250 rpm, thanks also to the 6-speed gearbox, and ensures unbeatable performance levels for its category, not only at high revs but also in terms of exploitable power, minimised vibrations and great reliability of the components.
There is a liquid-based cooling system and double overhead camshaft timing system (DOHC) with four valves. This engine also offers the advantages of reduced weight and extremely compact dimensions, thanks to the dry sump lubrication system that allows the development of an amazingly advanced chassis architecture.
