Honda CB300F (2015-2018) Maintenance Schedule and Service Intervals
This is the maintenance schedule and associated service intervals for the Honda CB300F, an entry-level standard motorcycle in Honda’s line-up made from 2015-2018.
The Honda CB300F is all about standard/naked sportbike styling at an entry-level price and demeanor. The Honda CB300F is designed to be lighter, smaller and simpler without losing the things you want from a modern motorcycle.
The Honda CB300F has a 286cc single-cylinder fuel-injected engine that provides excellent power delivery and fuel efficiency. With a 3.4-gallon tank and a claimed 70+ mpg, you might get through the week without stopping to fill up. The CB300F’s engine is the same unit in other similarly-sized motorcycles from Honda, like the Honda Rebel 300.
In 2018 Honda released the CB300R, a similar bike but with “modern retro” style, but using the same fundamental engine.

Maintaining Your Chain on the Honda CB300F
It’s important to maintain your chain on the CB300F, as on any chain-driven motorcycle, but particularly if you use your CB300F as a commuter — which can be remarkably high-stress for a motorcycle.
Use a good-quality chain lubricant like Motul chain paste, or a Motul chain care kit which comes with a couple of handy tools to maintain the chain.
Honda recommends you follow the following chain maintenance schedule:
|Chain maintenance item||Every|
|Check drive chain lubrication condition, lubricating if necessary||500 mi / 800 km|
|Check drive chain slack, adjusting if necessary||500 mi / 800 km|
- Do these items (checking/adjusting slack, and checking/applying lubrication) more often if you ride your CB300F in dusty or rainy conditions.
- Always lubricate the chain after washing the motorcycle.
Tyre size and tyre pressure for the Honda CB300F

About the Honda CB300F
The Honda CB300F is definitely aimed at beginner riders, or those looking for a practical commuter (or just something to do Uber Eats deliveries on when needing occasional freeway time).
The seat height is low, the seating position is upright, it’s very lightweight, and the power delivery is easy to manage.
Despite this, the styling and performance of the CB300F isn’t screamingly beginner, not as much so as a 125-cc motorcycle. The CB300F reasonably big, so if you’re six-feet tall you won’t feel like you’re sitting on a Honda Monkey, for example.
And the CB300F’s engine can keep you at highway speeds for short stints — though you probably won’t be heading with it to the Autobahn.
The Honda CB300F’s engine is a 286cc single-cylinder engine that is liquid cooled, has two overhead cams, and fuel injection. It’s very gentle off idle, but the short ratios on the six-speed transmission get you up to speed faster.
The Honda CB300F has 17-inch cast rims, ready for all your sporting fun!
Honda has put only a single, 296 mm disc with a two-piston caliper up front, and a 220 mm disc with a single-piston binder in back. It manages — only because the bike is so light weight.
The suspension is basic as you’d expect, but functional. The front forks are conventional (right-side-up) units with no adjustability, and the rear monoshock has a five-slot preload adjuster.
Maintaining the Honda CB300F is wonderfully simple. It just has one piston! Basic service intervals are every 8000 miles (12800 km), at which point you should change the oil and filter and do a bunch of checks. You check the spark plug and valve clearance every two intervals, and replace the air cleaner every three.
Aside from that, keep brake fluid and radiator coolant up to date (they have to be replaced every two years) and your CB300F will last longer than most other bikes on the road.
