Difference between revisions of "Harley-Davidson RR500"

Following the failure of their 250 and 350cc twins, [[Aermacchi]] created a 500cc version that was unique in that it had four [[carburetors]], two per [[cylinder]].  The [[motorcycle]] started in 1973 using an air cooled motor, but with the loss of their star rider, Renzo Pasolini, the factory lost interest in the project and it sat idle for two years.  A revised water-cooled version was tried but it was never the success it was hoped to be, and the project was turned over to another Italian company, [[Bimota]].
