2020 marks 50 years since the debut of the XR750, an iconic model that’s raced countless tracks and delivered podium finishes to its riders through countless AMA and American Flat Track (AFT) campaigns over the decades. It’s been drooled over, wrenched on, and beloved to this day, and for the big anniversary, Harley-Davidson has cooked up a couple of different ways to celebrate. One of them is to fly the flag proudly among its current crop of racebikes, so 2020 Harley-Davidson Super Twins and Production Twins bikes along with the Screamin’ Eagle/Vance & Hines NHRA Pro Stock motorcycles will be running with the historic Jet Fire Orange color (which will also adorn team haulers, uniforms, and branded accessories). The 2020 AFT season opener is the Daytona TT, so that aligns nicely as well (the Harley-Davidson Factory Flat Track team continues to field the liquid-cooled XG750R flat tracker with the 750cc Revolution X V-twin). Since the XR750 is often referred to as the “most successful racebike of all time,” racking up more wins than any other bike in AMA racing history, let’s do a quick rundown on how it got there.
