Sunflower Trophy: Glenn Irwin bids for maiden success at Bishopscourt meeting
Carrickfergus rider Glenn Irwin faces some stiff opposition as he bids for a first Sunflower Trophy success at Bishopscourt on Saturday.
The 26-year-old rides the Be Wiser PBM Ducati which took him to two podiums in his first season in British Superbikes.
Tyco BMW man Christian Iddon competes, along with Essex racer Danny Buchan, who aims for a third successive win in the event on board an MSS Kawasaki.
Fourteen races are scheduled for Saturday, with three on Friday.
After securing a third-place finish at the closing BSB round at Brands Hatch last weekend, Irwin will start as favourite to take the chequered flag in the 36th running of the feature race, which will be run over 12 laps of the County Down circuit.
Among the other leading entries are British Superstock 1000cc rider James East on a Gearlink Kawasaki, new Irish Superbike champion Nikki Coates and Masters Superbike champion Robert English.
Lisburn's David Haire rides a Kawasaki and will be joined on the grid by Nico Mawhinney, Jason Lynn, Gerard Kinghan and Cody Nally.
Among the leading contenders in the Supersport class should be Gearlink Kawasaki duo Carl Phillips and Andrew Irwin, plus regular British championship competitor David Allingham.
Practice for the meeting, run by the Hillsborough Club, starts at 09:00 BST on Friday, with three races to follow. Saturday's warm-up commences at 09:00.
