Why wouldn't YT match his salary? I suspect given YT's business model that they can risk paying out for a premier rider, even more so than many typically large brands. Maybe he lowered his expectations a little but still ended up doubling his salary. This is all speculation of course.
Gwin's salary was really low but its still quite a bit higher than $300k from what I'm told. What he asked for went into 7 figures.
FWIW, riders generally make more money now than they did back in the Palmer era, with a few exceptions.
And for those who don't know, ktm motorsports and ktm bicycles are two very different companies. ktm bicycles licensed the name, that's all.
My Guess is this, KTM and YT joint venture. KTM has a large Bike lineup. Gwin would help grow the brand internationally.
The amount of KTM Gwin has posted lately screams KTM involvement, even if KTM Bikes and Mountain bikes remain diff companies. Perhaps Gwin will be used to help e-bike sales.
