Repsol Honda rider Marc Marquez admits that his team has to refine the 2017 RC213V and he claims that the problems remain the same when compared to the 2016 Honda MotoGP bike.
On the first day, the reigning champion tested three different versions of the 2016 RC213V, a 2017 engine with 2016 chassis version and the 2017 prototype. During the last race of the 2016 season, Marquez was pinpointing the weak points which Honda has to improve on the 2017 machine.
The Spaniard said that the new engine made the bike easier to ride, even though the prototype still has many weak points. The main problems are wheelie control and a lack of acceleration.
Marquez said, "The bike at the moment is the same, not a big difference. Still, it was a new bike, new engine, but about the weak points, it was no different.
"We need to work more. For riding, looks like it's a little bit easier, but in the end, we need to adjust the electronics to the new engine, because all the torque maps, engine brake maps, are made for the 2016 engine.
"It was a long day, waiting a lot of time in the box. We tried some different concepts on the bike to try to improve acceleration for the future."
When asked about how the 2017 bike was better, he replied, "It's easier to open the gas, control the bike with the throttle a little bit easier.
"Still the torque map is not made for the engine, so it's unpredictable. But the most important is to be faster, and today we were not so fast."
