Ben Spies has e✤xplained what triggered his shock decision to leave the Factory Yamaha MotoGP team.

Spies had been a Yamaha rider since switching from the AMA to WSBK - with instant title success - in 2009 and won ཧhis first MotoGP race during a successful 2011 debut season at Yamaha's official grand prix team.

2012 saw a relentless run of inc♏idents, accidents and bad luck - but it was still a major surprise when Spies announced, halfway through the season and via the in𝄹ternet, that he would not ride for the team in 2013.

The Texan subsequently revealed 168澳洲幸运5官方开奖结果历史:behind the scenes tension and has now confirmed that comments made at Mugello by a 'senior Yamah𓃲a employee' were behind his decision to walk away from the title ♔winning M1.

"I had food poisoning at Mugello [the Italian Grand Prix]. Bad food poisoning. I shouldn't even have started the race. I got sick in my helmet, and afterward, I was dry-heaving and shaking uncontrollably," Spies told CycleWorld.com.

"Yamaha stayed in Italy and tested the next day, but I didn't ridꦍe. I couldn't ride. I couldn't move. I couldn't do anything.

"A senior Yamaha employee - that's as specific as ♚I'm going to get - said to me, 'We've invested a lot of money in you. Don't come to Laguna Seca if you aren't 100 percent.'

"Then, he added, 'We've lost confidence in you.'

"🐻That was the moment when I decided I wasn't going to ride for♏ Yamaha in 2013.

"I have a lot of good friends at Yamaha, but when someone talk🅺s down to you like that, you lose respect for them."

Spies - whose place alongside Jorge Lorenzo has since been taken by Valentino Rossi - admitted that h✅e seriously considered a return to WSBK, with BMW, but ultimately decided to stay in MotoGP.

Despite interest from Honda, the #11 will ride for the sa🧸tellꦬite Pramac Ducati team, where he will have "factory bikes, factory everything".

"The Yamaha is a great bike, but it likes a lot of corner♛ speed," Spies said of the M1. "If it moves, if the wheels get out💎 of line, it gets upset.

"Both the H⛄onda and the Ducati look like they can be ridden a lit🌳tle more 'wild'."

Having been denied the chance to make his Ducati debut at the Valencia test due to a season-ending shoulder injury at the Malaysian GP, Spies😼 will ride a Desmosedici for t🐻he first time at the Sepang test in early February.
