Eighteen years after their unforgettable Battle of the Twins victory, the Irving Vincent team is returning to Daytona with a familiar rider, a reunited crew and a two-valve, air-cooled V-twin built for one of the toughest racetracks in the world
In March 2008 Craig McMartin rode a hand-built Australian air-cooled twin to a landmark Battle of the Twins victory at Daytona International Speedway. It was a win that stunned the locals, elevated the Irving Vincent project onto the world stage and proved that two brothers from Melbourne – Ken and Barry Horner – could take on the high banks of Daytona and leave with a winner's trophy. Eighteen years later, the team is going back.
