Honda CBR300R Maintenance Schedule and Service Intervals

Honda CBR300R Stock Image

This is the maintenance schedule and associated service intervals for the Honda CBR300R, in production since 2013. The CBR300R has not changes significantly since.

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.

The new single-cylinder engine increased power from 19 to 23 kW (26 to 31 hp), and torque from 27 to 27 Nm (17 to 20 ft-lb). The new Honda CBR300R also came with optional ABS (standard in some markets), and with restyled fairing and headlight to resemble the CBR RR line of the time, a departure from the more “sport tourer” style of the CBR250R.

With its 286cc single, the Honda CBR300R shares a lot in common with other small singles from Honda, like the naked variant, the CB300R.

About the Honda CBR300R

The Honda CBR300R was an evolution of the CBR250R — a re-styling with a bigger engine, but still the same entry-level performance that’s great for new riders, or for many parts of the world where going much over 100 km/h doesn’t make much sense.

Honda rebuilt its 249 cc engine especially for the CBR300R. Honda increased the swept volume to 286 cc, keeping other aspects of it the same — it’s still a water-cooled, fuel-injected, four-cylinder thumper.

Internal changes include new piston, connecting rod and crankshaft, along with taller gearing for better cruising.

Honda designed the engine to provide smooth and manageable power — enough to get you moving without being overwhelming. It’s the same basic platform used in other 300-class motorcycles made by Honda, like the Rebel 300, so a lot of the maintenance schedule is the same.

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 manages air/fuel delivery. The CBR300R is fuel-injected, so a 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.

The little CBR300R has a six-speed transmission that helps keep the rpm within the usable powerband, sendinga power to the rear wheel via a chain drive.

Honda made some exterior changes as well. These included 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.

Tires and suspension remain same as CBR250R.
