Honda revealed a couple of concepts based on its 650 models at the 2015 EICMA show. Pictured here is the CB4, a naked roadster, which was joined by the CB Six50 scrambler. No official information was released, as they appear to be a simply design exercises from Honda R&D Europe and unlikely to develop into a production model (but we can hope!).

The CB4 concept is equipped with the 649cc Inline-Four powering both the CB650F and CBR650F with the same gorgeous cascade of four header pipes. Instead of the production models’ single underslung exhaust, the pipes end in a pair of stacked exhaust cans with carbon fiber heat shielding.


The frame, subframe and footpeg mounts also appear to be identical as the one on the CB650F but that’s where the similarities between the two naked models end. The 650F’s bodywork was replaced with a pair of large air scoops and a carbon fiber radiator guard.


The machined triple clamps frame a circular LED headlight, which matches the round instrument panel and bar-end mirrors. The upside-down fork appear to be the same as the one on the CBR600RR, as are the radial-mount Tokico calipers, though they are painted red on the CB4. The red matches the coil on the rear shock which suspends the CB4’s single-sided swingarm.


At the moment, the CB4 remains a styling exercise, but who knows what Honda may do if it draws enough interest.
