Honda CBR300R Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Honda CBR300R.

In October 2013, Honda released the CBR300R. The Honda CBR300R is a longer-stroke replacement for the long-serving CBR250R, increasing displacement from 250cc to 286cc, in response to Kawasaki’s Ninja 300.

Honda said the new model has increased horsepower, from 26 to 301 bhp (19 to 23 kW), and greater torque, from 17 to 20 lb-ft (23 to 27 Nm).

An optional ABS upgrade is available for these models. The new CBR300R differs from the previous CBR250R in a number of ways. The fairing and headlight are restyled to more resemble the CBR RR line – a departure from the CBR250R resemblance to the VFR1200F.

Further external changes include a new exhaust system and revised motor mounts, a new seat and side panels that aid in an easier reach to the ground and a slightly more sporty riding position. Internal changes include new piston, connecting rod and crankshaft along with increase in displacement and taller gearing for better cruising. Tires and suspension remain same as CBR250R.

About the Honda CBR300R

Honda rebuilt its 249 cc engine especially for the CBR300R. The factory increased the swept volume to 286 cc in this water-cooled, four-cycle thumper before plugging it into the frame.

Much like the rest of the bike, the engine was designed to provide smooth and manageable power sufficient to get you moving while not being so powerful as to get away from you. 

The oversquare engine runs with a 76 mm bore and longer stroke (lengthened from 55 mm to 63 mm) for a 17-percent increase in power over its predecessor.

A 38 mm throttle body meters air/fuel delivery and the onboard computer manages the ignition and timing advance for a long-legged 71 mpg.

Best of all, since most new riders could also be new mechanics, the engine comes laid out with ease of maintenance in mind with easy access to the valve adjusters, oil fill and filter and rear brake fluid reservoir.

A six-speed transmission helps keep the rpm within the usable powerband, and it sends the power to the rear wheel via chain drive.
