The 21-year-old Tobermore racer had signed to IMR Racing for the new season less than two months ago but parted company with the Manx team on Tuesday.

McLean, who was the fastest newcomer at the 2017 Isle of Man TT, will compete on Kawasaki ZX-6R and ZX-10RR machinery.

He will be partnered in the team by Englishman James Cowton.

"I am over the moon to sign for McAdoo Kawasaki. I'm sorry it didn't work out with Team IMR but when the team contacted me today I couldn't believe it got sorted out so quickly," said McLean.

A statement issued by McAdoo racing described McLean as the most exciting Irish rider to come along in a long time.
