Harley-Davidson XR750 from 1980 on Auction

by Daniel Patrascu from https://www.autoevolution.com Back in 1969, the AMA Grand National Championship rules changed enough that the dominant force of the time, Harley-Davidson, had to come up with something new to replace the KR750 it was fielding back then. It ended up unleashing into the world what was to become the series’ most successful motorcycle in history. XR750 is how it’s called, and it was introduced in 1970 in both flat track and road racing variants. Several big names of the competition rode the model, and managed to earn it 28 of 37 AMA Grand National Championships ran from 1972 to 2008. Last time we heard anything about the XR750 at an official level was in 2019, when Harley decided to use the Jet Fire Orange, the competition colors deployed by the Harley-Davidson Factory Flat Track team back in the day, across the company’s racing hardware. But despite this effort, nothing can match in appeal an original XR750. We managed to dig one up as it awaits a new buyer on Mecum’s Las Vegas sale at the end of the week. We’re not being told who was its rider back in the day, but that probably matters little for the ones eyeing to buy it. Sporting the native orange and black of its breed, the bike is ready for the track, it seems, and has even been fitted with new tires, ventilated hubs, rear sprocket and disc, and clean air filters. According to the seller, “track safety inspection looks ok to pass with springs and other updates.” The engine that powers it is the original 750cc unit, sporting the aluminum heads that replaced the iron ones in 1972, The motorcycle is presently part of the George Schott collection, but hopes are it will not be for long.

Harley-Davidson XR750 from 1972 on auction

by Daniel Patrascu from https://www.autoevolution.com 1972 Harley-Davidson XR750 Evel Knievel Is Not Quite the Real Thing, Comes Close In 2020, Harley-Davidson celebrated the 50th anniversary of the XR750 in style by wrapping the entire racing hardware it fielded, including the team haulers, uniforms, and branded accessories, in the iconic Jet Fire Orange, the competition color used by the Harley-Davidson Factory Flat Track team. But other hues are perhaps equally iconic for the model. The XR750 was introduced as a replacement for the KR750 in 1970, and quickly became the dominant force in the AMA Grand National Championships. In fact, the model is to date the most successful in the competition’s history, having won 28 championships between 1972 and 2008. The racing two-wheeler was ridden to success by the sport’s big names, including Jay Springsteen, Mark Brelsford, or Cal Rayborn. But an even more prominent name of the age is linked to it: Evel Knievel. One of the most famous stunt performers in history, Knievel rode the XR750 from 1970 to 1976. On the bike, he set a new world record by making it airborne and literally flying over 19 cars, a stunt that was filmed for his namesake 1971 movie. The record stood for 27 years when it was taken to 20 cars by Bubba Blackwell, also riding an XR750. Like all stuntmen, Knievel identified himself through several iconic elements, including the colors he used on his rides. And in charge of making his bikes and helmets stand out was his favorite painter, George Sedlak. The bike you see in the gallery above is not one directly linked to Knievel but is painted as a replica by Sedlak—after the stuntman retired, the painter began working on such projects on request. This one sports the colors red, white, and blue on

Harley-Davidson celebrates 50th anniversary of XR750

The 2020 season marks the 50th year since the debut of the XR750, a motorcycle raced, wrenched on, and beloved among the American Flat Track (AFT) paddock to this day. To celebrate the anniversary, Harley-Davidson Super Twins and Production Twins bikes along with the Harley-Davidson Screamin’ Eagle/Vance & Hines NHRA Pro Stock motorcycles will feature the historic colour of Harley-Davidson competition motorcycles, Jet Fire Orange, along with team haulers, uniforms, and branded accessories. “The XR750 is the winningest motorcycle in AMA Pro Racing motorcycle history,” said Jon Bekefy, general manager of brand marketing at Harley-Davidson, Inc. “Harley-Davidson is taking its 50th anniversary as a moment to reflect on the legacy and individuals who have designed, engineered, tuned, and raced the XR750 during its years of competition, and to celebrate Harley-Davidson’s 2020 racing efforts.” Born in 1970 with the advent of the new AMA Racing equivalency formula, the XR750 was created by Harley-Davidson’s race team manager Dick O’Brian and team to replace the highly successful outgoing KR750. Using a Harley-Davidson Sportster-based engine, the XR750 utilised modified cast-iron heads and cylinders, a magneto instead of generator, and improved oiling. In 1972 a new, more powerful all-aluminum alloy XR750 engine was introduced. The perfected machine dominated flat track racing for decades to come. Between 1972 and 2008, the XR750 would go on to win 28 of 37 AMA Grand National Championships. The XR750 racked up more wins than any other motorcycle in AMA racing history and earned the description of being the “most successful race bike of all time.” In addition, the XR750 became a cultural icon with legendary stuntman Evel Knievel at the handlebars. Evel Knievel began jumping an XR750 at the height of his career from 1970 to 1976, and alongside the exploits of the racing versions of the XR750 inspired
