When Harley challenged them to create a custom bike using one of their classic designs, the guys at Keystone Harley found inspiration not in motorcycles, but in race cars.

The bike builders revealed their design on Saturday at the dealership, then took it to the PPL Center in Allentown to share it with a couple thousand Phantoms fans.The "GT Sporty" is a Harley-Davidson Sportster, completely transformed into something inspired by the iconic Ford GT40 race car from the late 1960s.The most obvious take-away from the car is the head-turning blue and orange paint, and the sleek, speedy lines, but it takes other aspects from the GT, including having the exhaust come directly out of the back fender - something rarely seen on motorcycles, according to bike builder Jimmy Holt.It also takes some inspiration in the engine department - sporting a Harley engine that has been modified to produce more horsepower.While the bike looks like no other Harley out there, Holt said it was built all with Harley parts, so that an enthusiast could build one without investing in expensive metal fabricating equipment.It's also meant to inspire riders and show them that the same can easily be done to their stock Harley."We wanted somebody to be able to walk in and say, 'I like that. How do I do that?' " he said. "It's really about your imagination."The team also spared no expense on details like the bike's paint, which was essential to re-creating the GT40.The exact GT that inspired Holt was the one driven by actor Steve McQueen in the movie "Le Mans." While that car carried number 6, the GT Sporty is number 5 to commemorate the dealership's fifth anniversary.Starting next month, fans will have a chance to vote for the bike from Carbon County as it takes on designs from dealerships across the country."We think this is the 'King of Customs' this year. We think we have a winner," Holt said.
