Triumph Rocket III Maintenance Schedule

2010-2020 Triumph Rocket III Roadster -Stock Image

This is the maintenance schedule with associated service intervals for the Triumph Rocket III Roadster motorcycles.

This is the service schedule for the earlier Rocket III (not the Rocket 3)! These had a “smaller” 2,300 cc engine and less electronics. But they were still stomping motorcycles, and maybe these are the ones you’re looking for.

This maintenance schedule applies to all models of the Rocket III, including the Rocket III Classic, the Rocket III Roadster, the Rocket III Tourer, and the Rocket III Touring (subtly different). By far, the most popular was the Rocket III Roadster.

What you need to service the Triumph Rocket III motorcycles

The Rocket III may be a big, 2,294cc motorcycle, but it’s not difficult to service — once you get your head around the massive weight!

If you’re planning on doing it yourself — maybe you’re just changing the oil or plugs — then you’ll need the following consumables.

Firstly, you need to see if you have the basic motorcycle maintenance tools — nothing shocking, just things like a paddock stand, oil filter wrench, and so on.

The following is a list of specific consumables for the Triumph Rocket III series of motorcycles.

OilCastrol Power 1 4T 10W-50The manual suggests semi or fully synthetic 15W-50 (at least) which meets specification API SH (or higher) and JSO MA, such as Castrol Power 1 4T 10W-50 (fully synthetic).
Oil filterTriumph oil filter T1218001Replace the oil filter every time you change the oil. Use Triumph part number T1218001. You can also use K&N part KN-204-1.
Spark plugsLMAR8A-9 spark plugs Triumph Rocker IIIUse NGK spark plugs with code DPR7EA-9 (sold individually). Make sure they’re gapped to 0.9mm with an appropriate spark plug gapping tool.
Air filterTriumph T2200987 air filterUse Triumph part number T2202203 or K&N equivalent part TB-2204.

You may also need the following general consumables for servicing your Triumph Rocket III.

Chain lubricantmotorcycle maintenance tools - motul chain pasteThe chain needs to be lubricated every 800 km/500 miles (or more, if it gets wet/dirty), with variations recommended between manufacturers. Motul chain paste is cheap and well-loved.
Chain cleaner brushmotorcycle maintenance - chain cleanerA chain cleaner brush makes cleaning off grime and then distributing new lubricant much more easy.
Paddock standmotorcycle maintenance tools - paddock standLubricating the chain and changing the oil both become a lot easier once you use an affordable paddock stand (not necessary if you have a center stand).
Cable lubricantmotorcycle maintenance - cable lubricantRemember to lubricate your clutch cable (and brake cables if you have them) with a cable lubricant. Protect All Cable Life is a good general-purpose lubricant.
GreaseGet a good lithium soap based grease for lubricating major components like your side stand, centre stand, and bearings.
General motorcycle consumables — Brake fluid, chain lube, clutch lube, and grease

General information about the Triumph Rocket III Roadster

The Triumph Rocket III Roadster had the biggest engine of any production motorcycle in the world. The massive motor on the Rocket III certainly allowed it to live up to its name, thanks in large part to output numbers that hit 148 horsepower at 5,750 rpm and 163 pound-feet of torque at 2,750 rpm.

It has now been eclipsed by the even-bigger Rocket 3 R and Rocket 3 GT, but that doesn’t mean the Rocket III was small or underpowered!

It’s not (and it wasn’t) the fastest bike in the world but that’s not the point. What you get is unbridled power that can still hit a standing quarter-mile in just 12.2 seconds to go with a top speed of 137 mph.

The Rocket III was popular, and is now a niche collector bike, because it never really found its footing in the conservative US cruiser market.
