Honda Rebel 300 (CMX300) Maintenance Schedule and Service Intervals

Honda Rebel 300 Matte Blue Jeans Metallic maintenance schedule cover

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, and very little sibling to the 2021 Honda Rebel 1100. 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 powerband 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?

Aside from basic motorcycle maintenance tools, here’s what you need to service your Honda Rebel 300.

PartHonda CB300F and Rebel 300 spec

Oil filterUse Hiflofiltro HF103 for the oil filter as a high-quality drop-in replacement (People prefer Hiflofiltro to K&N in recent years for oil filters).
Air filterYou can use the K&N air filter as an easy-to-find replacement. Part number is K&N HA-2513.
Spark plugsUse NGK spark plug part SIMR8A9.
Chain maintenanceTo maintain your chain, Motul chain paste is quite well-liked. There’s also the Motul chain care kit which is affordable and good (it includes a brush, gloves, and cleaning solution)

Honda Rebel 300 Maintenance Schedule

Below is the maintenance schedule for the Honda Rebel 300.

Servicing the Rebel 300 is cheap and easy. You inspect the valves — all four of them, on the one cylinder — every 16,000 miles or 14,000 km. It’s basically a naked bike, so everything’s there for you to see and work on. (Ed: I have to get me one of these! Well, maybe a 500. Or an 1100…)

Honda marks the rough difficulty level of each maintenance procedure (in the “Dif.” column)

  • X: Intermediate. “We recommend service by your Honda dealer, unless you have the necessary tools and are mechanically skilled.”
  • XX: Technical. “In the interest of safety, have your motorcycle serviced by your dealer.”

Of course, use your own judgment.

Maintenance Procedures:

  • I: Inspect and clean, adjust, lubricate, or replace, if necessary

About the Honda Rebel 300

2020 Honda Rebel 300 city background skyline

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 fuel injected. You might recognise this engine from other “300” motorcycles from Honda, like the Honda CBR300R.

It’s a great entry-level bike, not just because of its modest power, but also because it has very low cost of ownership. It gently sips fuel and all the components — tyres, brake pads/rotors, and engine components — are low-cost.

Unlike many affordable bikes, the Rebel 300 has quite wide maintenance intervals. It’ll take a long time until you get to the first valve service — and it’ll be a doddle, and cheap to do.

Honestly every time I see a Rebel 300 or 500 I think to myself: Why aren’t I riding one of these?

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 has been standard in many parts of the world.

Honda kept the Rebel 300 effectively the same every year since its launch, making only minor tweaks to things like suspension, and changing the colours/graphics, none of which affects maintenance.
