With Jorge Lorenzo's second place in the MotoGP race at the Australian Grand Prix on Sunday, Yamaha clinched the 2015 manufacturers' championship for the first time since 2010, and 37th time overall, making the Japanese motorbike giant the equal-second most successful Grand Prix bike builder of all time.
Honda's Marc Marquez won Sunday's race on Australia's famous Phillip Island circuit, his fifth victory of the season and Honda's sixth overall, but Yamaha riders' championship rivals Lorenzo and Valentino Rossi have shared 10 victories, as well as a number of other point scoring performances in a season where the Movistar team's consistency has been its biggest asset.
Yamaha Motorsport's General Manager Koichi Tsuji said that the team focused on winning the manufacturers' title this season, and with the Movistar team already wrapping up teams' championship, and Rossi and Lorenzo having already ensured the riders' championship will go to a Yamaha rider, 2015 will be a perfect year for Yamaha.
"I am very pleased because we have achieved more goals than one," said Tsuji in a team statement. "Not only did we see Yamaha take the team and manufacturers' world title, adding to Yamaha racing's DNA and its successful history, we also got to share these indescribable experiences with our fans around the world."
The 2015 title puts Yamaha equal on the all-time list with famous Italian manufacturer, MV Agusta, which has not won a race since 1976 and currently does not build a Grand Prix bike in any class. Honda, which won the crown between 2011 and 2014, leads the way with 63 titles.
Riders' championship leader Rossi finished the Australian race in fourth, two places behind Lorenzo, which allowed the Spanish rider to cut Rossi's championship lead to just 11 points. Rossi can potentially wrap-up the riders' championship at the next round in Malaysia if Lorenzo fails to finish and Rossi finishes third or higher.
"We already said that race results were going to be important 10 rounds ago, but now it's really important and it will be very tough until the last race," said Rossi after Sunday's race.
