The 1975 Harley-Davidson RR 250 motorcycle was made in Italy. It featured a liquid cooled, twin cylinder two stroke engine. The ignition was from a magneto on crank. The engine was rated at 53 b.h.p. at 11,800 r.p.m. The displacement was 246cc based upon a bore and stroke of 56 X 50 mm. Fuel was supplied via two Mikuni carburetor. Getting the power to the ground was by a six speed transmission. The suspension featured front Ceriani telescopic forks with twin shocks in the rear. Braking was provided by front Scarab double discs and rear Ceriani drum. The motorcycle weighed in at 240 pounds. Top speed for the bike was 120 m.p.h.

According to the museum's fact sheet "Available through your local Harley-Davidson dealer, the RR250 was eligible for AMA Class C racing. The U.S. versions used Mikuni carburetors, while the European counterparts had Italian Dell'Orto. Ceriani four leading shoe drum front brake was standard equipment, but this machine has the "factory only" twin disc set-up. These machines were built by Harley Davidson's subsidiary, Aermacchi. Harley needed a line of small capacity entry level machines to attract younger potential customers into their dealerships, so they purchased this old established company."
