Dunlop has a Honda Fireblade for the Superbike class, plus a Kawasaki ZX-10R Superstock machine and a Suzuki GSX-R600, previously raced in the British Supersport class by Marty Nutt.
"I know where I'm at with my Superstock bike because I've won races on it last year - it's fast and I have all my settings from last year, so we've a good start with the 'Stock bike," he added.
"That leaves me free to put my main efforts into the Superbike and the 600cc Suzuki. The Suzuki is a new bike for me, so I want to get it right. It was raced by Marty Nutt but we'll be building our own engine for it.
"We had the 600 Yamaha R6 at its maximum last year so the chance was
there to try something different so I thought we'd have a go at it."
