It's a lame excuse that is being given out for Rossi not being able to podium. He's supposed to be the most versatile rider in Motogp history but has now been unable to adapt to 2 bikes that weren't tailor made for him.
When Lorenzo joined Yamaha in 2008 it was Rossi's bike. Lorenzo had never ridden a Motogp bike (which means nothing in my view but that's another issue) He put it on pole twice in the first 3 races, one of which was the first, and podiumed his first 3 races, the third of which was a win. This was the bike we are being told in other threads that would stop and turn on a dime to suit Rossi's late breaking turn it in style - the complete opposite of Lorenzo's brake early and carry corner speed. Lorenzo coped, Rossi should be able to do the same now.
After Qatar he was full of praise for the bike, nothing wrong with it, but in reality, as well as he rode, a result that was possible as both Hondas had grip problems. Then came the poor results and the excuses about the bike. At Aragon he found a solution and then won Assen, but the reality was that the Hondas has grip issues again with CC splitting them on a satellite Yam. The next races were not true reflections of riders' respective speed due to injuries but by Indy it was situation normal and back to a distant 4th, fighting with satellite bikes - even with the solution from Aragon and it's been the same since. Malaysia is an untypical track with it's long staights, so yes he was closer. Maybe he has found another solution, the next three races will tell, but an objective look at the season's results so far suggest he just isn't fast enough. I'm prepared to be proved wrong if the next three races show otherwise.
The argument over the Honda being suprior to the Yamaha is subjective. It always will be unless you get a rider who is able to try both and take them both to their absolute limit around several tracks and then deliver an impartial opinion on their respective performance. Lorenzo is hardly going to say the bikes are about equal but I'm losing because MM is a better rider is he. I believe that if Lorenzo hadn't injured himself at Assen, he still be leading, as he was then with more points and more wins than MM. The Yamaha isn't so bad.
