Sorry, misunderstood you, my bad. Anyhow, I'm not lookin for a pissin match, a preferred bike could be debated for the next century. In closing though, if you took 10 guys, and gave them both bikes stock at a track and gave them 10 laps. I'd bet my left hanger that 8 of them would be faster on the Aprilia.
That's it for me on the topic, all the best with your Duc and glad it's workin for ya.
But its not about that. . . just because a certain subset is faster doesn't necessarily equate to sales. if it was - then the BMW S1000 would have 8 out of 10 of /all/ sales out there - as I'm reasonably certain it would beat the Ape and Duc. . . So saying the majority would choose the ape is just plain incorrect - people choose bikes for a myriad of reasons and fastest on the track is but one of those elements to a minority subset.
Just like something like the porsche 911 Turbo (or GTR) would clean up most other cars on the track, but people still buy Ferraris, Lambos, etc because there is a bit more panache associated with it. . .
Here is an interesting thing - if someone were to offer a group of 10 people to ride any of these bikes for a month, free of charge what do you think the results would be ?
BMW S1000rr
Ducati Panigale R
Aprilia RSV4 APRC Factory
I'm reasonably certain that the RSV4 would come in last - but mainly because they don't know about the bike. It would probably be close but my guess is the pani would take the edge, followed by the s1000 and then the Aprilia.
Now, lets throw one more into the equation.
BMW S1000rr
Ducati Panigale R
Aprilia RSV4 APRC Factory
Ducati Desmo D16rr
I'm reasonably certain that the Desmo would win this overwhelmingly. . . But wait, you could bet not one but both of your hangers that people would be faster on any of the three previous bikes over the desmo. . Why would they choose one of the others ? its because people have certain desires/wants/cache's that are perhaps met by certain marques and not others. So purchases (outside of racing) aren't necessarily met by buying what you're fastest on . .
