William Dunlop will ride a specially prepared Kawasaki for MSS Performance and Colchester Kawasaki in the Superstock class at the 2016 Isle of Man TT and a number of other races.
William will ride the bike at the North West 200 and Ulster Grand Prix and will take in selected rounds of the 1000cc National Superstock Championship and some Irish national road races.
The 30-year-old's efforts in 2016 will be co-ordinated by CD Racing and he will ride Yamaha machinery in the Superbike and Supersport categories.
"If I'm really honest I wasn't too sure about the Superstock class but when I heard we had the option of running with Nick (Morgan of MSS) and understood the whole package I became really positive," said William.
"I'm excited to be doing it properly with testing and some BSB rounds, which mean I'll be sharp for the TT.
"Chris Dowd (of CD Racing) sorted the deal and Nick and his guys have fantastic knowledge and data on the ZX-10R in this spec.
"The team seem a really relaxed group to deal with and that's just how I like to go racing."
