HARLEY-DAVIDSON XR750TT - 1972 Harley-Davidson XR750TT One of the top European concours d’elégance shows is the Salon Privé. It’s held on the manicured lawns of Syon Park, just outside London, and is more than a petrolhead paradise—it’s also one of the top events on the English social calendar. Last year, motorcycles were admitted to the Salon Privé concours for the first time. And this year, the ‘Important Competition Machines’ class was taken out by the magnificent Harley-Davidson XR750TT you see here. 1972 Harley-Davidson XR750TTFull Size The bike is now owned by King’s Road dealer Warr’s Harley-Davidson, and it’s one of ten factory-built racers from 1972. It was the ultimate expression of the XR750 line, with twin carbs, Ceriani front forks, a four-speed gearbox and a double-sided 4LS front brake. 1972 Harley-Davidson XR750TTFull Size This particular machine was campaigned on road circuits in the US and Warr’s has restored it to original spec, finishing it off in the colors of the legendary Harley factory rider Cal Rayborn. (The #3 livery was used for the Transatlantic Trophy Series at the Brands Hatch and Mallory Park circuits.) 1972 Harley-Davidson XR750TT by Warr'sFull Size In a neat twist, Warr’s mechanic Walt Faulk was the man who tuned the XR750TT back in the day, enabling Rayborn to pull off some stunning wins on circuits he’d never ridden before.
