This 1972 Harley-Davidson/Aermacchi SX350 Sprint is a street-legal scrambler based on the contemporary SS350. The original owner kept the bike through November 1996, when the second owner found it in a local classified ad. The second owner participated twice in the Portland Black Mountain Trail run in the 1990s, and the selling dealer recently acquired it after a period in storage. The bike is powered by a 350cc single-cylinder engine with a 4-speed transmission, and the selling dealer got the bike running and replaced the black vinyl seat. This SX350 is offered by Denwerks at no reserve with records from the previous owner, factory literature, and a clean Oregon title.
The bike features Banana Yellow fenders and a tank with fluorescent orange graphics, which was only offered for the 1972 model year on Italian-built Harley-Davidson models. The bodywork is contrasted by a gloss black frame and matte black lockable storage cubby, and the seller has replaced the black vinyl seat. Close-up photos of the finish and graphics are provided in the gallery below.
The chrome wire-spoked wheels measure 19″ in diameter at the front and 18″ at the rear and are fitted with Bridgestone Trail-Wing dual sport tires. The SX350 was delivered without turn signals according to an included 1992 article in Rider Magazine, and the bike retains factory lighting as well as a high-mounted exhaust system.
The original speedometer-odometer failed when the bike showed around 4k miles, and the fitted replacement now shows about 1k miles. The original unit is included with the sale. The bike retains factory motocross-style raised handlebars, factory controls, and a single mirror.
The 344cc single-cylinder engine is paired with a 4-speed transmission and was rated at 25 horsepower, and the bike is equipped with a kick-starter and a right-side foot shifter. The selling dealer got the bike running again after its time stored by the previous owner. The seller reports that the bike was stored without fuel, and required fresh fuel, a spark plug, an oil change, and a battery to return to running condition. A selection of older records are available from the previous owner.
Included literature and manuals are pictured above. The gallery features close-up photos of included records, an article on the model from Rider Magazine, the copy of Hood River County Shopper ads where the previous owner found the bike, and the title.
