With virtually no detailed information, Honda published photographs of three motorcycle prototypes it will display at the 40th Tokyo Motor Show beginning October 27 in Chiba, Japan. The three concepts include the Evo 6 (pictured above) which appears to feature a version of the Gold Wing flat six engine, and two retro-style, air-cooled inline-four cylinder machines, the CB1100F and CB1100R.
We had reported earlier that Honda is rumored to be developing a retro-styled machine (based on the original CB750) for possible future production. These latter two concepts may point in that direction.
