Honda CBR300R Maintenance Schedule and Service Intervals

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

The Honda CBR300R is a longer-stroke replacement for the long-serving Honda CBR250R, increasing displacement from 250cc to 286cc.

The new single-cylinder engine increases peak power from 19 to 23 kW (26 to 31 hp), and torque from 23 to 27 Nm (17 to 20 ft-lb). The Honda CBR300R also comes with optional ABS (standard in some markets), and with a restyled fairing and headlight to resemble the more recent other models (like the 2013-2018 CBR500R).

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

Tyre size and tyre pressure for the Honda CBR300R

In the manual for the Honda CBR300R, Honda specifies the following tyre sizes and standard brands for tyres, plus gives the following recommended tyre pressures.

Stock, the CBR300R ships with IRC RX-01 tyres, but you can fit other road/sport tyres as suits your riding style.

Tyre	Size	Brand(s)	Tyre pressure
Front	110/70-17M/C 54S	IRC RX-01FD	29 psi (200 kPa, 2.00 bar)
Rear	140/70-17M/C 66S	IRC RX-01RZ	29 psi (200 kPa, 2.00 bar)

About the Honda CBR300R

The Honda CBR300R is Honda’s entry-level road/sportbike. But it shares good looks and high build quality with the rest of Honda’s modern line.

The CBR300R is an evolution of the previous 2001-2013 Honda CBR250R. It has a bigger engine, with a longer stroke (55mm lengthened to 63mm), increasing displacement from 249.5cc to 286cc.

It has a bigger engine and new style, but still gives the same accessible performance that’s great for new riders, those wanting to downsize, or people in many parts of the world where going much over 100 km/h (60 mph) doesn’t make much sense.

Honda kept the compression ratio of the CBR300R at 10.7:1, just like its predecessor, but the bike still gets a ~15% power boost from the greater displacement and accompanying tune. Power is still pretty modest, with a peak of 23 kW (30 hp) at 8500 rpm.

Otherwise, the bike’s engine is very similar conceptually. It’s still a liquid-cooled fuel-injected single-cylinder engine.

Internally, Honda gave the bike a new piston, connecting rod, and crankshaft, along with taller gearing than the CBR250R for better cruising.

The engine is the same basic engine used in other 300-class motorcycles made by Honda, like the Honda Rebel 300, so the general maintenance schedule is the same.

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, sending 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 the previous model CBR250R.

Front suspension is via a conventional fork that’s not adjustable, but the rear monoshock has five-position preload adjustability.

Braking is also simple, as you’d expect on a low-power bike, with a single 296 mm disc up front and a 2-piston caliper.
