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.

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.
