Aprilia RS4 125/50
A successful motor sports career can start here. She has also realized.
As a rising star in the circus 1000PS I've never been a really long road on a super athlete. A few laps at Pannoniaring (parking lot), maybe, but never before. On a racetrack Do not believe I could, when I saw the invitation to the Aprilia RS4 presentation in Milan discovered in the inbox. NastyNils finally recognized my full potential! Finally Supersport in the premier class. Perfect down to the "V", which I had intended on writing simple model. And thus the lack of cubic and PS. The invitation was the RS4 125 and 50 presentation. Unfortunately, no world champion Max Biaggi bike, I'll ride. Or does it?
Even Biaggi and Rossi began at once small.
Even the world champion and podium riders, so the really big ones, had to start small again. And this is not just a saying of parents so that they do not attack after the driving test is equal in the 1000 class. No. Since 1992 Aprilia in the 125cc and 250cc very successful in business. Names like "Valentino Rossi", "Max Biaggi" or "Stoner" have in the 125cc class with Aprilia recorded their first racing success. Those who do not believe it can find, (HERE) a long list on the Aprilia website. A total of 342 victories in various classes since 1981. Development, research and countless rounds on various racetracks around the world brought Aprilia to where they are today:
On the list of the most successful European brands. The RS 125, which has been driven for years by a two-stroke engine, has now been revised and provided with new racing spirit. The design is based very heavily on the bike world champion Max Biaggi. The sleek lines and the entire front of the RSV4 look confusingly similar. Looks can be deceiving in this case. LED taillight and clear instrument panel, "Underfloor" exhaust and passenger pegs, which can be for track use quickly and easily. This shows that the RS4 has provided not only for the typical Sunday ride. Although a comfortable seating position and not too deep mounted handlebars were certainly designed with a view to the longer exit.
A world champion bike for learning.
From there the new driving license rules 2013 (report) it already for the youngest junior racer with 16 years the opportunity to enter on a world champion bike. I for one would then even sold my grandmother for such a moped. (Sorry, but is so.)
If several ticking like me, there could be many to buy the latest in 2013, relatively cheap grandmothers. The price is also very tempting.
On the small but excellent test track south of Milan, I could even sniff first air race and the RS4 125 test extensively in two versions. A normal version and one with the optional "quick-shift" circuit for the wild clean chopping without domes (optional for 90 €). In showrooms will shine three different colors: Black Racing, Racing White or the special edition with the colors of the replica SBK teams.
The main innovation concerns the 125 cc version. This has been completely revised and is not driven as in previous years by a two-stroke, but a water-cooled single-cylinder four-stroke. This able-bodied right from approximately 5,000 rpm. 11.500 From the limiter regulates gentle but demanding. If you are sitting on the quick-shift variant, one has in turn definitely the time advantage. Simply push in the gas and stay. Without fuss.
The weight of 145 kg can be casual contact through the corners. The speed stop at the first rocket of course limited. H 126 km / I could see again, just before the radial four-piston caliper, operated via a standard braided hose, biting back into the disc.
No 180 hp. But a very good start ..
The upside-down telescopic fork at the front and the aluminum swingarm with single-shock rear keep the sports equipment quietly on track and communicate when braking or accelerating out of a sense of security. A sense of control that you can so you have only one super athlete. Feel what the front tire is doing and how the steering pulse acts. You can tell that the ancestors of the RS4 come directly from the racetrack and the racing genes are also entered into them. Certainly not to the detriment of driving pleasure. OK, there are no 180 hp to 180 kg, which you drive. But it's definitely a very good start ...
