As we expected from previously released design trademark diagrams and certification from the California Air Resources Board, Honda has revealed a new naked version of the the CBR300R dubbed the CB300F.

The 2015 Honda CB300F shares the same chassis and 286cc single-cylinder fuel-injected engine as the CBR300R. The engine itself is similar to the CBR250R’s powerplant, but with the piston stroke increased to 63mm from 55mm. As with the 300R, the CB250F uses an exhaust resembling that found on Honda’s 500-series models. Besides the naked styling, the CB300F differentiates itself from the CBR300R with its more upright seating position, thanks to its higher handlebars.


The rest of the specs sheet closely resembles the CBR300R’s. The suspension system uses a 37mm telescopic fork with 4.65 inches of travel up front and a Pro-Link rear shock with five-position spring preload adjustability and 4.07 inches of travel. The braking system uses the same two-piston caliper and 296mm disc up front and 220mm disc at the back. Unlike the CBR300R however, the CB300F is not available in the U.S. with anti-lock brakes.

Visually, the CB300F resembles the larger CB500F, with a similar single headlight and radiator shrouds. Other features include an LCD multi-function display, 3.4-gallon fuel tank and a claimed fuel economy of 71 mpg.

The 2015 Honda CB300F will arrive in showrooms this fall, but only in red. American Honda is pricing the 300F at $3999, compared to $4399 for the CBR300R and $4899 for the CBR300R with ABS.
