Since Ian Lougher's first-year win in 2002, all big names of road racing have been considered, such as Adrian Archibald, Richard Britton, Jason Griffiths, Darran Lindsay and, more recently, Manxman Conor Cummins.
The records show a split between Ryan Farquhar and Ian Lougher, apart from 2007 when Manxman Conor Cummins received the award in only his second full-season on the roads.
The series received coverage in leading publications, such as Motor Cycle News, Road Racing Ireland and Bikesportnews, culminating in an annual presentation gathering.
Manxman Conor Cummins took the honours in 2007; Michael Dunlop in 2013; Yorkshireman James Cowton 2014; William Dunlop 2015, with the title going to Yorkshire for the second time in 2016 in the hands of Dean Harrison, who retained his title in 2017, taking top spot in the rankings table from the first round, taking seven race wins from seven starts and putting in seven fastest laps and holding that position throughout the 25 rounds.
The twenty-three round series which commenced at the Mid Antrim 150 National Road Races in Northern Ireland in early April and concluded at the recent Macau Motorcycle Grand Prix saw Dean making a cautious start to his 2016 season, his first with the Silkolene Engineering Yamaha Team, before dominating the Duke Road Race Rankings from late June.
The twenty-seven year old Yorkshireman joined the rankings at the second round at the Bob Smith Spring National held at Oliver's Mount slotting into third place slipping to ninth prior to the first International, the North West 200, recovering to eighth, then climbing back to third after the TT, topping the table after the Cock o'the North Road Races at Oliver's Mount, round 10 of this year's series.
Rising star Malachi Mitchel Thomas riding for the John Burrows 'Cookstown' Team headed the 2016 rankings after the opening round at Mid Antrim and remained on the top rung until the TT, despite his untimely passing at the North West 200, such was his early season dominance.
The twenty-four round series which commenced at the Spring National Road Races at Oliver's Mount in April and concluded at the recent Macau Motorcycle Grand Prix saw William having a season long battle with fellow 'pure roads' rising star Ivan Lintin which was only resolved at the final round in the Southern hemisphere when the chequered flag fell.
Neither William or Ivan had been invited to race at the tight, twisty closed public roads circuit, the Geoff Duke Trophy looked set to be returning to Ballymoney where it had spent 12 months, two years earlier.
Ivan making his debut on the 3.8028 mile Circuit da Guia course had to finish in the top six to snatch the championship series from his Ballymoney rival.
William Dunlop opened his Duke Rankings account at the second round, the Cookstown 100 taking 13th spot in the table, quickly moving into third after a very wet Tandragee 100, the climbing to second after the North West 200.
A double race victory and record lap at the 'Race of Legends' at Armoy William was back in second spot and so to Dundrod and the Ulster Grand Prix in mixed conditions a 2nd; 4th; 5th; 6th & 10th was enough to put the Tyco Team rider at the top of the Duke Rankings becoming only the sixth rider to see his name engraved on the coveted Geoff Duke Trophy since the Championship Series started in 2002.
Yorkshire's James Cowton becomes the 13th winner of the Duke Road Race Rankings series since its inception in 2002 and the first English rider to collect the prestigious award.
Ryan Farquhar said he was 'made up' to win his sixth Duke Road Race Rankings Series after another superb season on his KMR Kawasaki machines.
Manxman Conor Cummins, who placed fifth, two sixths and an eighth at TT, secured the top position in the rankings during his first full-year of pure road racing.
2006 The twenty-five round series were held at all national and international road races in the north and south of Ireland, the Isle of Man and England.
