Milwaukee Power Tools has refuted speculation that it will support Michael Dunlop at the Isle of Man TT this year.

The company - the title sponsor of Shaun Muir's MCE British Superbike and international road racing team - announced last weekend it was withdrawing its backing of Muir's outfit at the TT as a result of new rules preventing Yamaha from running its after-market Magneti Marelli system.

The change in regulations limits teams to a Motec or kit ECU - a decision Muir and Milwaukee believe leaves their riders, Ian Hutchinson and Josh Brookes, at a disadvantage.

However, conjecture this week suggested Milwaukee Power Tools would instead throw its weight behind Northern Ireland's Michael Dunlop at the TT, who is linked with a ride on a factory-supported BMW S1000RR.

However, the claim has been 'categorically' rejected by Milwaukee.

The company's UK Commercial Director, Dale McElveen, told the Belfast News Letter: "I can categorically state that we have no plans to support any other rider at the Isle of Man TT on any type of machinery.

"This is a long-term project with Yamaha and we are looking ahead to many exciting plans in the future. We have made our decision to withdraw our support of Shaun Muir's team at the TT because, as we have already stated, we believe the rule changes place Ian Hutchinson and Josh Brookes at a disadvantage," he added.

"We will not have any role at the TT this year and have other plans to announce soon."

Milwaukee will continue as the title sponsors of Muir's team in British Superbikes and at the North West 200, Ulster Grand Prix and Macau Grand Prix.
