Ben Spies has explained what triggered his shock decision to leave the Factory Y🔯amaha MotoG💞P team.

Spies had been a Yamaha rider since switching from the AMA to W♎SBK - with instant titl♍e success - in 2009 and won his first MotoGP race during a successful 2011 debut season at Yamaha's official grand prix team.

2012 saw a relentless run of incidents, accidents and bad luck - but it was still a major surpris🌠e 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5最新开奖结果: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 title win💯ning 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 Iꦿtaly 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 as꧒ 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 f☂or Yamaha in 2013.

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

Spies - whose place alongside Jorge Lorenzo has since been taken by Valentino Rossi - admitted that he seriously considered a ret💙urn to WSBK, with BMW, but ultimately decided to stay in MotoGP.

Despite interest from Honda, the #11🌺 will ride for the satellite Pramac Ducati team, where he will have "factory bikes, factory everyt🥀hing".

"The Yamaha is a great bike, but it likes a lot of corner s♚peed," Spies said of the M1. "If it moves, if the whe🍷els get out of line, it gets upset.

"Both the 𓂃Honda and the Ducati look like they can be ridden a little more 'wild'."

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