you are right, the bike is new, and future will show how good it is. Furthermore, we need to admit, that the superbike world championship bikes are far away from the bike you can buy.
But, in two topics, you are wrong.
1.) First victory for BMW
This was not Melandri. This was Ayrton Badovini. They startet in 2010 and not 2009, as far as i know, and Ayrton won 9(!) out of 10 races in the world superstock championship. This was a victory the panigale was not able to do... because french Silvain Barrier won last year again on the BMW. And the superstock class is much more like the bike you can buy in the store.
But that is not the real point, in my humbe opinion. The real point is:
2.) the concept
Actually, the Panigale is something special. But it is based on the concept, with which Ducati failed srupulously in the motoGP. And that concept should be the base for new winning bike for the superbike championship? Maybe. Most likely not.
Last not least:
3.) first year win -> Aprilia
Aprilia also started with a new bike... and won the championship directly.
By the way: Not to mention, that in Aragon, Sylvain Barrier on the superstock S 1000 RR was not really much slower then Checa on the ducaty...
4.) success in motoGP
Sorry, but they won't have success against Honda and Yamaha in MotoGP. Not as long as they can get a driver like Stoner again.
