Honda CB350

The Honda CB350 was a 325.6 cubic centimetres (19.87 cu in) OHC parallel twin cylinder, four-stroke motorcycle produced by Honda for model years 1968 through 1973. Its reliable motor, coupled with dual Keihin carburetors, proved to be a popular design, becoming Honda's best-selling model. More than 250,000 were sold in five years, with 67,180 sold in 1972 alone. In 1968 it was the best-selling motorcycle worldwide. The machine evolved cosmetically over the course of its production with incremental engineering improvements to the suspension and brakes.

Like its predecessor, the CB77 Superhawk, the CB350 was also offered in scrambler form, as the CL350, with high-mounted exhausts and a 19-inch front wheel, and as the SL350, with upswept exhausts and off-road styling.

The four-cylinder CB350F, a completely different model, was introduced in 1972 and the Honda CB360 twin became a short-lived replacement for the 350 twin in 1974.

A black café racer-styled CB350 with an upswept CL350 exhaust customised by Glory Motor Works, was used in the 2011 movie The Girl with the Dragon Tattoo.
