Inspired by the early 70’s XR – TT 750 Road Racer, this is our version of a late model Harley Sportster featuring a full vintage throwback road race aesthetic with the high performance attributes to match. The XR TT was legendary in it’s time, a championship winning machine based on the Harley Davidson XR 750 power plant that dominated both road racing and flat track. The silhouette of the XR-TT has left a historic mark on roadracing just as the XR 750 has in Flat Track racing. It’s shape brings back memories of historic Daytona victories coupled with the rumble only an air-cooled American V-Twin can produce. Of course building an original for the Street would be just about impossible and would come with a nearly unobtainable price. Enter the Sportster and the evolution of the Original XR 750 into today’s Aluminum Cylinder Twin Cam, American Vtwin. As we move into the REvMax Platform and water-cooled sportster, this is the last of the Air Cooled Sportsters, ending an age that started with the Harley K model in 1952.

With some respect to the past we wanted to update the rolling kit with as much performance as possible. We started with An Ohlins FG right side up fork with a Radial Mount Brembo Caliper and wave rotor. We used 15” Fox shocks out back to get ground clearance as well as tighten up the fork angle. 17” x 3.5” RSD Morris wheels with Dunlop Sportmax Q5’s complete the spinning bits. Airtech XR-TT bodywork originally built for a rigid mounts Sportster have been highly modified for the XR-TT Sporty. Aaron from RSD fabricated the Body mounts and modfied the fuel tank to fit the Glass Fuel Tank cover. S&S Cycle high flat track style pipe keeps the XR theme flowing.

Much more to come as we wrap this one up over the coming weeks and get it ready for paint!
