William Dunlop is set to compete in the first six rounds of the British 125cc championship this year.
The 26-year-old will campaign a Honda, which will be supplied by Mark Keen of KRP Racing.
"Mark is not running a team this year, he is just building a bike for me, so I know it will be the best machine he can possibly build," said Dunlop.
"I've had some decent results in the past but this will be a better bike and I should be pushing for podium spots."
"It will also help sharpen me up for the big road races," added Dunlop.
Dunlop will again ride for Wilson Craig Honda at the major international road races, as well as selected national events.
