BRADFORD'S Dean Harrison, watched by HRH Prince William, gave a dominant performance to win today's second Supersport race at the Isle of Man TT.

After a third place and a runners-up berth earlier in the week, Harrison (Kawasaki Silicone Engineering) led from lap one to lap four, with Peter Hickman (Triumph-Trooper Triumph by Smiths Racing) and James Hillier (Kawasaki Quattro Plant JG Speedfit Kawasaki) filling the minor podium positions.

Prolific TT winner Michael Dunlop (Honda MD Racing) might have figured, but dropped to sixth after receiving a 30-second penalty for a pit-lane infringement and ended up fifth.

Harrison was already 1.8sec ahead by Glen Helen on the first lap, and that was extended to 2sec by Ballaugh, 2.7sec at Ramsey and 2.9sec at Bungalow, with Harrison recording 169.9mph through the speed trap at Sulby.

His avaerage speed on lap one was 128.188mph, and that was increased to 129.99mph by the finish of lap two by which time Harrison's lead had grown to8sec.

Dunlop's penalty then ruled him out of the equation, and the Bradfordian was 18 seconds in front of Hickman at Glen Helen the third time around.

Althugh that advantage grew to 21sec by Ramsey and Bungalow, Harrison was able to eliminate any unnecessary risks and finished 18.8sec in front of Hickman, with Hillier in third.

Bingley's Ian Hutchinson (Honda Padgetts) was 11th and Dean's brother Adrian 30th on his Honda Martin Smith Ground Works machine.
