Newly crowned 125cc world champion Arnaud Vincent will take his number one plate to KTM for next season.
Vincent, who became the first Frenchman ever to win the title, will ride alongside 2000 champion Roberto Locatelli in the Red Bull sponsored squad.
Vincent said: " With KTM I think I have the best chance of defending my title.
" The KTM/Red Bull structure includes the best brains in the paddock. That and the speed with which KTM became a dominant force in off-road motorsports convinced me. "
