Aprilia Mille R - by Tom Montano
|
| Several weeks ago I came home from another day at the grind. There was a message from the editor of American Roadracing/2wf.com; he wanted to know if I could go to Spain for the Aprilia RSV Mille R launch. I asked myself, "Should I go to Spain and ride the new bad ass Aprilia…?" Without hesitation, I returned his call; too bad for him he is too busy to go. |

A week before my trip, a friend took out one of the standard Mille RSVs from Scuderia West-our local San Francisco Aprilia dealer-and after flogging it around the city, he told me that it was a bitch'n bike. The next thing you know, I'm on a plane for Spain laughing the whole way in anticipation.
The RSV Mille R is meant to bridge the gap between the ultra trick, very expensive ($32,000.00), hard to get (150 units only, this year) RSV Mille SP and the standard RSV. The Italians have produced some very beautiful bikes over the years and this is no exception. I hoped it worked as good as it looked.
The first morning in Spain it was raining a little at the track. Never fear, we grabbed our stuff and piled into a van and headed to it. The Valencia circuit is a great track that's only a few years old. The track surface is smooth and the layout is real cool; not too fast with plenty of turns and hard braking spots. There are a few tricky spots, too, like the big sweeper leading up to the last hairpin. You just don't know how fast to go, then you can't quite tell where to start braking so you tend to brake too early or to overshoot. The grandstands circle three quarters of the circuit so the spectators can see the whole track layout pretty much from anywhere they sit, and the garages are state of the art. It must be like a crazy bullfight there when the races are going on, people yelling from every corner of the track and you'd see and hear them all.

The Mille R features an Ohlins upside-down 43 mm fork with titanium nitride coating on the tubes and gold anodized sliders. External rebound and compression adjustments are easy to use, and the brake hanger is a one-piece forged aluminum bracket that is more rigid than conventional caliper mounting plates. The rear shock is also an Ohlins unit with the usual compression and rebound adjustments. There is plenty of room between the swingarm and subframe, so spring preload can easily be adjusted. |
| One of the big things about the R model is its revolutionary wheels. The OZ wheel company, a front runner in F1 car technology, produced the lightweight wheels with just the right amount of rigidity. The wheels are made from Anticorodal 5051 forged aluminum in an 8000 ton forging press. This technology enabled the production of a wheel free from porosity. A finite element analysis proved that the six spokes dividing towards the edge of the channel was the best choice and that this structure in fact permits optimum lateral and torsional rigidity. The weight saved on these wheels is exceptional, about 25% less per wheel compared to the lightest OEM cast aluminum rim. The wheel weight reduction reduced the wheel's inertia by 25%, which should make the bike more "flickable." The manufacturing process allowed the wheels to be as light as magnesium wheels but without the corrosion problem. |
