In 2013, at the China International Motorcycle Trade Exhibition in Chongqing, the Japanese motorcycle manufacturer announced the longer-stroke CBR300R, an upgraded model from the CBR250R that featured an increased engine displacement. The bike was a response to Kawasaki's Ninja 300 model.
Compared to the CBR250R machine, the 300R developed more horsepower, from 26 to 31 hp, and more torque, from 23 to 27 Nm. The bike was also available with an Anti-Lock Braking System (ABS) that enhanced safety and handling capabilities.
The CBR300R was different from its predecessor in several ways, such as the fairing and headlight, which were restyled to more resemble the CBR RR line, a new exhaust system, new engine mounts, a new seat and side panels that offered an easier reach to the ground, and a slightly more sporty riding position.
Some of the internal changes included new pistons, connecting rods, and crankshaft along with an increased displacement and taller gearing for better cruising, while the tires and suspension remained the same as on the CBR250R model.
For suspension, the bike packed a 37 mm telescopic fork on the front with 120 mm of wheel travel and a five-position preload adjustable shock absorber on the rear with 103 mm of wheel travel.
For stopping power, the bike featured a single 296 mm disc with a two-piston caliper on the front wheel and one 220 mm disc with a single-piston caliper on the rear wheel for optimum braking performance.
As for the power figures, the 2014 Honda CBR300R took its muscles from a 286cc four-stroke single-cylinder liquid-cooled engine that delivered an output power of 31 hp at 8,500 rpm and 27 Nm (20 lb-ft) of torque at 7,250 rpm.
