Marc Marquez will roll the dice and try last year's Honda chassis during this weekend's Dutch MotoGP round at Assen.
Marquez has struggled with unpredictable rear-end slides from the latest RCV, hurting his previous corner-entry strength and forcing him to place ever more faith in the front tyre.
After falling for the second time in as many races, Marquez stepped back to the 2014 chassis (fitted with the 2015 engine, exhaust and swingarm) for the post-race Catalunya test.
The Repsol Honda star reported “the feeling was good”, although a rain storm wrecked his chances of a full evaluation and he only completed a handful of laps on the chassis.
But with non-scores in three of the seven races dropping Marquez 69-points behind title leader Valentino Rossi, and 68 from Jorge Lorenzo, Marquez has little to lose by taking risks with his machinery.
“We know the weather can be unstable here but I tried [the 2014 chassis] in Montmelo. It was good and I will use here," said Marquez, confirming what Honda had told Crash.net
earlier in the day. “The feeling [with the 2014 chassis] was more-or-less what I had last year. I was able to do more mistakes and less risk.
“With this year's [2015 chassis] we are able to be really fast over one lap, but during the race it is so difficult to be consistent and just one small mistake and you crash.
“I think we are getting closer to the solution - to the confidence and the feeling of what I had last year. But it is not a case of finding one solution to put on or off and everything will work.
“I think we need to continue in this way because every race I feel better. In Mugello and Montmelo we worked hard and now we have a base, but still we need to work because both Yamaha riders are strong. It is not only their bike - they have good confidence and are pushing a lot.
“We know it will be difficult to beat them here, but we will try to be closer and even closer again in Germany.”
Due to the MotoGP development freeze, which currently applies only to Honda and Yamaha, engine design cannot be changed during the racing season.
Rossi and Lorenzo will have a new Yamaha chassis to try this weekend, after a positive test at Aragon.
