Ben Spies has explained what triggered his s𒈔hock 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 his first MotoGP race during a successful 2011 debut season at Yamaha's ܫofficial grand prix team.

2012 saw a relentless run of incidents, accidents and bad luck - but it was s🐻till a major surprise when Spies announced, halfway through the season and via the internet, 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 Yamaha employee' were behind his decision to walk away from the t🌳itle 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 ride. 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 ge𒐪t𝐆 - 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 mom꧟ent when I decided I wasn't going to ride for Yamaha in 2𒉰013.

"I have a lot of good friends at Yamaha, but when someone talks d♏own to you like that, you lose respect for them."

Spies - whose place alongside Jorge Lorenzo has since been taken by Vale♛ntino Rossi - admitted that he 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 satellite Pramac Duca✱ti team, where he will have "factory bikes, factory everything".

"The Yamaha is a great bike, bu✱t 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 th♛e Honda and the Ducati look like the🦋y can be ridden a little 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.
