The inclusion of the teams to compete against Sky, BMC and Giant-Alpecin among others means there will be more Yorkshire riders on the start line.
The Yorkshire quartet of track star Ed Clancy, Graham Briggs and the Moses brothers, Tom and Joe, ride for JLT Condor.
Rotherham’s Ben Swift leads the home charge for Sky, one of 10 local riders who could line up in Bridlington on May 1.
Other Yorkshire riders who could feature include Russ Downing (Cult Energy), Pete Williams (One Pro Cycling), Tom Barrass (NFTO), Liam Holohan and Tom Stewart (Madison Genesis).
There are 18 teams now in the inaugural Tour de Yorkshire, which runs from Friday, May 1, to Sunday, May 3.
