Description
The Honda CB1100R was an exotic Honda model that was produced in limited numbers from 1980 to 1983. It was a single-seat sport bike based on the Honda CB900F, initially with a 3⁄4 fairing and exposed lower engine. The R suffix denoted a racing version, however the CB1100R was a road-legal machine produced by Honda and offered for sale to the public. It was produced only in numbers sufficient to meet the homologation requirements for the R to be classed as a production motorcycle in markets into which it was sold. It was Honda’s real first ‘homologation special and was not sold in the US. In 1981 there were a reported 1050 units produced, and 1500 for each of the 1982 and 1983 years.
