Valentino Rossi and Maverick Viñales are not fast on all routes. Yamaha technician Kouji Tsuya explains why this is and where the strengths of the latest chassis lie.
"Our 2017 Yamaha has not shown a good performance during the races like in Jerez and Catalunya this season, but the tires did not fit our bike. This is one of our strengths - the Kurvenspeed. Our riders Rossi and Viñales were no longer able to achieve the desired lap times, "emphasizes Kouji Tsuya, 2017 M1 Project Leader and MotoGP Group Leader.
After the Catalunya GP, a new chassis was tested there on Monday, which had overall advantages, but since then also revealed weaknesses on some of the slopes.
And this was brought to a time when the Tech3 Yamaha team delivered strong performances with Folger and Zarco - followed by the GP of Germany in second place. The Tech3 team used last year's motorcycles.
Nevertheless, rookie Johann Zarco has defeated nine-time world champion Rossi in three races three times already.
"In Barcelona, we had one more day to test after the Monday test. There, with Valentino and Maverick, we compared this year's chassis with the last year, "says Yamaha technician Kouji. "In addition, we had prepared two update chassis from 2017, that is the new one. But both have judged the brand new chassis as the best. It has been used since then. From both factory pilots. »
They are primarily the low-grip tracks Yamaha suffers. In Brno, Yamaha finished with riders 3 and 4 with Viñales and Rossi. Lastly, Viñales won in Silverstone, Rossi finished third.
Valentino Rossi born 16 February 1979 is an Italian professional motorcycle road racer and multiple MotoGP World Champion. He is one of the most successful motorcycle racers of all time, with nine Grand Prix World Championships to his name – seven of which are in the premier class.
