Donington Park was the venue for the new MotoSix Nations Challenge, over a cool but sunny weekend.
In the solo classes the Isle of Man had a strong team, made up of Gavin Hunt, Mark Cringle, Chris Palmer, Callum Collister, Stephen Oates, Ryan Kneen, Tim Venables and Mark Madsen-Mygdall.
They finished fifth overall with 667 points while Northern Ireland won the event with 347 points.
Points were allocated from one down to 36 with the higher placed riders getting the lower points so the team with the fewest points were the winners.
Northern Ireland rider Alastair Seeley dominated proceedings by taking both the 600cc and 1000cc events.
Representing the Isle of Man in the sidecar class was Nicky Crow and Mark Cox, Dave Molyneux and Dan Sayle, Karl Bennett and Lee Cain, Neil Kelly and Jason O'Conner and Dave Quirk and Matty Bartlett.
But it was Bryan Peddar and Rod Steadman for England who took a double win in the sidecar category.
