It doesn't make sense for someone who is used to write and read sh!t for sure, you should stick to the Legoland forum because M-C is too complicated a subject for you.
Bultoboy: Because according to you, there have been a Rossi and a Burgess to require the changes they made to the 2013 M1 when Ben Spies was there?
Rossi, Spies and the Espargaro brothers have one common point, and a very obvious one, they ride their bike on the front, so Spies struggling on Lorenzo bike from the time they increased the wheelbase mid-2011, has everything to do with Rossi struggling on 2013 and Pol/Aleix having less issues with their M1 since Yamaha made changes to it last season.
Fact is Pol can ride like Marquez and also adapt to a more balanced version of the M1, which is what Rossi seems to have this year, and next year there are strong possibilities that either Aleix or Pol are going to be on a full factory bike and in any case this year chassis.
When Yamaha Racing looks at the time sheets and see Marquez being faster in most sectors, they are not stupid and can see the reason why, especially with Rossi skills at developing bikes.
Last year Marquez couldn't manage tyres and race 100% on a new bike and new category or else he would have won 10 GP like Stoner in 2011, this year he is even more potentially dangerous for Yamaha.
They can't rely on him getting injured to retake the title so they have to make the bike faster where it was slower last year. Simple logic.
It shouldn't be necessary to point this out when people READ MCN or any other serious source about GP all year, apparently either your bunch doesn't or you really have a block with low-level technical matters.
