Honda CB300F (2015-2018) Maintenance Schedule and Service Intervals

Honda CB300F Stock Image

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. In 2018 Honda released the CB300R, a similar bike but with “modern retro” style, but using the same fundamental engine.

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.

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. It’s not a tiny bike by any means, so even if you’re six feet tall it feels fine. And the engine can easily keep you at highway speeds (in most parts of the world… maybe not the Autobahn!)

The small displacement engine on the Honda CB300 does require a generous hand on the throttle through. With a 286cc single-cylinder engine, albeit one that is liquid cooled, DOHC and fuel-injected, and Moto3-inspired, power off idle is soft. The short gearing of the CB300F’s six-speed transmission helps you get up to speed faster.

The Honda CB300F has 17-inch, cast rims, and nearly symmetrical tyres with a 110/70 up front, and a 140/70 tire in back.

Honda has put only a single, 296 mm disc with a twin-pot brake 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 4.65 inches of travel and blackout fork sliders to match the rims. The rear monoshock has a progressive-link system, with 4 inches of travel and a five-slot preload adjuster.

A single-downtube and stressed engine frame sets the stage for the various features, and gives the CB300F the contemporary UJM look, which is to say a sporty standard.

The steering head is set at 25.3-degrees, and the trail measures out at 3.9-inches long.
