The 70's were a hit parade of classic motorcycles from Honda. After the success of the CB750 in convincing consumers that a bike should start each time and not leak oil all over the place, Honda brought out a full line of CB's. In 1972 they brought out the CB350F, which used an exquisitely designed, small 350cc inline 4, but was under powered for American riders (even in the 70's). In 1975 they upsized the motor to 408cc's and renamed it the CB400F. Find this 1975 Honda CB400F for sale in Seattle, WA for $3,400 via craigslist.
The Honda CB750 was introduced in 1969 and is considered to be one of the bikes that was key in changing the perception of Japanese motorcycles. In the 60's Japanese bikes were considered to be cheap, inferior products, but 10 years and 400,000 units later, the big CB is partly responsible for the current success of Japanese bikes. Riders found them to be well engineered, reliable, affordable products that didn't leak all over your driveway. Forty two years later, a good percentage of them are still going strong.
