The Honda CB900F is a standard/sport motorcycle produced by Honda from 1979 to 1983. Known as the Honda CB900 Bol d'Or in some European markets, it was a significant model in Honda's lineup, showcasing advanced engine technology for its era and aimed at the high-performance motorcycle market.
Development and History
The CB900F was developed during a period of intense competition among Japanese manufacturers for dominance in the large-displacement motorcycle segment. Following the success of the CB750 Four, Honda sought to produce a high-performance machine that combined cutting-edge technology with practical rideability. Its development was influenced by Honda's racing success, particularly in endurance events like the Bol d'Or 24-hour race, from which it derived its European moniker. It was designed to compete with powerful bikes like the Kawasaki Z1/Z1-R and the Suzuki GS series, offering a blend of power, handling, and Honda's renowned reliability.Technical Specifications
