Ballymoney, Northern Ireland's William Dunlop, who claimed the championship in the Irish National supersport division this season, has mutually parted ways with Tyco BMW.
His new outfit will see the young rider competing on Yamaha R1s with CD Racing, a team from Randalstown, with multiple backers including Eugene McManus, and owned by Chris Dowd.
The team boasts former Yamaha World Superbike team engineer Marcus Eschenbacher wrenching on the bikes behind the scenes.
After a "long-conversation" at the conclusion of the 2016 season, Dunlop and Tyco BMW team manager Philip Neill decided to part ways.
Dunlop's Supersport championship this season was won on a Yamaha R6, making the Superbike switch a slightly easier transition.
"Philip and all the boys at Tyco BMW were very good to me, so first of all I’d like to thank them for making me feel very welcome. I really enjoyed my two years with the team,” he said in a statement.
Dunlop was poised for a strong performance at the TT this past year but an injury in a practice shunt would keep the rider from contending the win at the Mountain Circuit in June.
