2026-09-19 12:50:00 2026-09-19 13:00:00 America/Los_Angeles 1970 Harley-Davidson XR750 Great Falls, Virginia - The race bike that defined American flat track. Harley-Davidson’s XR750 became one of the most successful competition machines ever built. https://iconicmotorbikeauctions.com/auction/1970-harley-davidson-xr750/ Iconic Motorbike Auctions concierge@iconicmotorbikes.com

Please Note: The seller has not started the bike during his ownership, as such there is no cold start video.

For decades, Harley’s XR750 was the machine to beat. From 1972 to 2008, the XR was responsible for taking home 29 out of the 37 possible AMA Grand National Championships, leading to some referring to the machine as the “most successful race bike of all time”. The XR750 was also famously Evel Knievel’s go-to choice when performing jumps/stunts. Before it was replaced a couple years back by H-D’s new XG750R, the XR750 was Harley’s primary platform in racing with the road-racing XRTT machine being a slightly modified, full-faired version of the American dirt tracker.

After new AMA regulations in 1969, Harley would be prompted to update its KR racer. Harley-Davidson’s then racing manager, Dick O’Brien, and his team utilized existing elements of designs to create a new OHV racer, as OHV bikes had began dominating flat track racing. The XR750 was the moco’s answer to the machines coming from Europe and Japan around the dawn of the ’70’s. The XR was largely derived from Harley’s 900cc Sportster-based XLR, only using a markedly shorter stroke and smaller connecting rods to bring displacement down to a regulation 750.

At the center of the XR750 was an air-cooled, 748cc V-Twin that made a reported 82hp at 7,700rpm and had a claimed top speed of 115mph. The Milwaukee-built V-Twin inhaled via dual 36mm Mikuni carbs and was married to a four-speed transmission with chain final drive. Wrapped around the American engine was a steel twin loop cradle frame fitted with telescopic Ceriani forks up front and dual Girling shocks in back. The whole bike sat upon a set of spoked aluminum rims, and weighed in at under 300lbs (dry).

This example is VIN: 1C100771H0. The seller acquired it in 2013 from the original owner via a MidAmerica auction in Las Vegas, Nevada.
