Based on an 883cc Sportster, the amazing machine offered here is a replica of the Harley-Davidson ridden by the late Cal Rayborn in the 1972 Trans-Atlantic Match Race Series. Back then Rayborn's mount was a seemingly outdated 'iron-engined' XR750, which did not stop the American dirt-track star winning three out of the six races against the cream of domestic opposition on circuits he had never seen before! Enlarged to 1,480cc, this machine's fully rebuilt engine incorporates an S&S bottom end; S&S '600' cams and roller followers; high-compression pistons; adjustable pushrods; and fully ported and gas-flowed cylinder heads. Induction is via an S&S Super carburettor and the motor is also fitted with a Warr 2-into-1 exhaust. Other noteworthy features include a hydraulic clutch with carbon plates; alloy wheel rims; Progressive fork springs; Hagon rear suspension; and Harrison Billet disc brakes. This machine was built from the ground upwards by its owner of some 12 years, who spared no expense in completing this most impressive project, as evidenced by the large quantity of bills in the comprehensive history file. Ready to ride or parade, this unique Harley-Davidson is offered with MoT to July 2016 and old/current V5C documents.
