Honda CB1300 (2003-2020, PGM-FI) Simplified Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Honda CB1300, made since 1998 and still made but only in Japan.

The Honda CB1300 was originally launched in 1998, but updated in 2003 with Honda’s PGM-FI fuel injection. Over time there have been further refinements, with optional ABS added and various cosmetic changes.

But at its core, the Honda CB1300 has always been the same. It’s a big naked bike powered by a liquid-cooled 1284 cc four-cylinder engine. The engine has always been a torque-forward one, making a peak of around 75 kW / 100 hp at 7500 rpm, though revving out to 10000 rpm as needed.

The final drive of the Honda CB1300 is a 5-6 speed transmission (depending on model year) and chain drive.

Like the Honda CB400 SF, the CB1300 is no longer available in most global markets.

Honda CB1300 Service Intervals

The Honda CB1100 has 8000 mile or 12000 km minor maintenance intervals at which you change the oil. But you only check the valve clearances every twice that — 16000 miles or 24000 km.

The CB1300 has both a hydraulic clutch as well as brake, so keep fluid in both fresh with Honda DOT 4.

And remember, unlike many other big naked standards, the CB1300 is liquid-cooled — so keep the coolant fresh.

Honda CB1300 Maintenance Schedule

Below is the maintenance schedule for the Honda CB1100. We’ve split it into two parts:

  1. Periodic maintenance, and
  2. The standard service checklist.

Maintenance Procedures:

  • I: Inspect and clean, adjust, lubricate, or replace, if necessary
  • R: Replace
  • L: Lubricate
  • C: Clean

Notes:

  • At higher odometer readings, repeat at the frequency interval established here.
  • The break-in service is omitted (usually a dealer does this during the warranty period)
  • Earlier models required changing the oil filter with every oil change. Many owners still do this but it’s up to you.
  • Honda recommends you get a dealer to do all maintenance related to emissions (inside the engine, idle speed, exhaust, etc.), and steering (bearings, tyres).

Maintaining Your Chain on the Honda CB1300

It’s important to maintain your chain on the CB1300, as on any chain-driven 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 itemEvery
Check drive chain lubrication condition, lubricating if necessary600 mi / 1000 km
Check drive chain slack, adjusting if necessary
Target slack: 25-35 mm
600 mi / 1000 km
Chain maintenance — Honda CB1300

Notes:

  • Do these items (checking/adjusting slack, and checking/applying lubrication) more often if you ride your CB1300 in dusty or rainy conditions.
  • Always lubricate the chain after washing the motorcycle.

After adjusting the slack, tighten the rear nut with 113 Nm / 83 lb-ft of torque.

About the Honda CB1300

The Honda CB1300 is one of Honda’s standards that is modern while at the same time being a nod to former glory days, like the Honda CB900F (the original one).

It’s quite different to Honda’s other more conspicuously “retro” motorcycles like the Honda CB1100. For starters, the engine in the CB1300 is liquid-cooled. And the CB1300 is more of a mainstay, still produced years after the CB110 was retired, and much in its original form.

The heart of the Honda CB1300 is its massive inline four-cylinder engine. It is a 1284 cc motor with a long-stroke 78.0 x 67.2 mm configuration, which goes hand in hand with the CB1300’s torque-forward configuration.

The engine in the CB1300 makes a claimed 84 kW (114 hp) at 7500 rpm, with a big wall of 86 lbf-ft (117 Nm) of torque at 6000 rpm — but you can feel most of that torque seemingly from right off idle. The CB1300 pulls right away, and pulls hard.

The CB1300 draws on Honda’s history in big fours, with the most recent predecessor being the CB1000 “Project Big One”. All the big Japanese manufacturers have dabbled in big fours, but the CB line is iconic.

What differentiates the CB1300 from other big retros like the Yamaha XJR1300 and the Suzuki GSX1400 is that the CB is — shockingly — liquid-cooled. Classic enthusiasts may cry foul at this, but it helps with Honda’s reputation for reliability.

As you might expect from a big 1300-class bike with a steel cradle frame, the CB1300 isn’t light. That’s where it falls over relative to competition from newer naked bikes that makes similar (or more) power but with much more highly tuned suspension and chassis packages. For example, Honda’s much more modern “Neo-Retro” 2018+ Honda CB1000R is the same general concept (a retro-ish bike) in a far lighter, more powerful, and maybe even attractive package. Which is why maybe bikes like the CB1300 no longer have a market footing.

But the CB1300 is still an engaging ride, with style elements that you don’t find on newer bikes, like twin shocks, twin gauges, and a big, comfortable, and inviting riding position on a standard naked bike.

Unfortunately over time, Honda has removed the CB1300 from most global markets. You can still find them, but low-mileage ones are rare (and even more so if you’re limited by budget as they have reached “niche classic” status). But they can still be found.

Manual for the Honda CB1300

The above maintenance schedule comes directly from the user’s manual for the Honda CB1300 from 2009, but we checked it going back to 2003 and up to 2020 (Japanese language manual) just to make sure nothing changed.
