he still has another season to go but only yamaha is still running the old style bike, you look at the other manufacturers like Kawa & Zuki they have way different bikes from last year, no carry over from the 990cc bike while the 800cc M1 is a spliting image of it's 990cc predescessor.
This is incorrect. The Suzuki is HEAVILY developed from the 990. The Kawasaki is even less so, but still much of the componentry is very much the same. You are right to say that the M1 is very similar to its 990 counterpart as well. Whereas Kawasaki and Suzuki determined last year that they'd begin developing the 800s during the 990 era, they were building towards the future and that development has borne fruit for this year's 800s.
The M1 however is, like you said, borrowed technology instead of innovated technology. The only bike on the grid that's totally new from the ground up is the Honda. But talk to anyone including Hopper in the Suzuki paddock and they'll tell you the Suzuki 800 started its component development on the 990s from last year. Honda did that in part with the evo211, but much of it was scrapped as testing and the year progressed.
At any rate, I did see it, but it's not definitive what happened to the M1. It looked like it clunked and lost front suspension or braking component broke. It might have been something they did in order for Rossi to ride it, but definitely, the combination of the M1 AND Michelin rubber did Rossi in, not just yesterday, but towards year end.
The M1 was competitive out of the box and it's not that it's stop being competitive, it's just that the competition has surpassed the flatlining M1 on the way to developing better 800s.
