Tech 3 is going to leave Yamaha at the end of the 2018 MotoGP season after an 18-year long partnership with the manufacturer. This bit of information was announced before the final pre-season MotoGP test.
According To Autosport, what prompted this decision was lack of factory support for Johann Zarco. He performed very well in his MotoGP rookie season in 2017, taking sixth place in the championship with two podium finishes.
In light of these accomplishments, Poncharal was hoping Yamaha would provide them with factory Yamaha equipment this year. That’s what Honda did with LCR rider Cal Crutchlow and Ducati showed their support of Pramac's Danilo Petrucci in a similar manner. But Zarco had to go through the pre-season tests with last year’s bike instead of the latest-spec YZR-M1 for 2018.
"Everybody was expecting maybe something a bit special coming from Yamaha to support Johann”, said Poncharal. “You always want a bit more, you always want to be a bit closer to the factory guys.”
Now Tech 3 has signed a new 3-year deal with another manufacturer and the contract includes full factory support for of the team's bikes. No official brand was named, though it was hinted that the new deal was with KTM.
