The CB350 was a 325.6 cc (19.87 cu in) OHC parallel twin cylinder, four-stroke motorcycle produced by Honda for model years 1968 through 1973.[2] Its reliable motor, coupled with dual Keihin carburetors proved to be a popular design, becoming the highest selling motorcycle in American history, with 300,000 units sold. The machine evolved cosmetically over the course of its production with incremental engineering improvements to the suspension and brakes.
Like its predecessor, the Honda CB77 Superhawk, the CB350 was also offered in scrambler form, as the CL350, with high-mounted exhausts, 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.
In the UK at this time learners were limited to motorcycles of 250 cc, and the sleeved-down CB250 K4 was a popular sight on British roads, often in yellow. The 350 was relatively unusual, identical in appearance except for the colour, always green.
