2017-2020 Honda Rebel 300 Stock Image

This is the maintenance schedule and associated service intervals for the Honda Rebel 300, replacing the earlier Honda Rebel 250.

The Honda Rebel 300 is an entry-level cruiser, the little sibling to the Honda Rebel 500. It has a 286cc, four-stroke, water-cooled single-cylinder engine which powers the rear wheel through a six speed transmission and a chain drive.

The Rebel 300 is a very accessible bike. It has a very low 690mm (27.2 inch) seat height, and modest power band that will get you going around town, but will be singing a little high on the highway. It’ll cruise quite happily at 120 km/h or 75 mph on a flat, which isn’t bad for a little single!

Also, maintaining the Rebel 300 is dead easy. One cylinder; who needs more?

About the Honda Rebel 300

The Honda Rebel 300 is a classically styled and practical cruiser, but with modern style elements and technology.

The Rebel 300 has a 286cc liquid-cooled 20-degree single cylinder four stroke engine with four valves in its one cylinder. It runs a very modest 10.7:1 compression ratio, and is of course fully fuel injected.

The Rebel 300 puts power down via a six-speed transmission and a chain final drive. It’s geared very low — you’ll be out of first gear in no time!

The Rebel 300, like the 500, comes with optional ABS — though it’s standard in many parts of the world.

Honda kept the Rebel 300 effectively the same every year, making only minor tweaks to things like suspension.
