What you need to service the Triumph Rocket 3 motorcycles

So you want to service your own 2,500cc behemoth, do you? Or maybe you just want to know exactly when you’re going to have to plonk down for a Triumph tech to do it for you.

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 3 series of motorcycles.

General information about the Triumph Rocket 3 GT

The Triumph Rocket 3 GT has incredible road presence and almost needs no introduction.

It was introduced in 2020 as an update to the earlier Triumph Rocket 3. A massive 2500cc engine gives 165Hp at 6,000 rpm with oodles of torque from way down low, up to a higher redline of 7,000 rpm.

The new Rocket 3 also has much more technology than earlier editions, with ride controls and cornering ABS. It all adds up to a fairly sumptuous riding experience that’s as good for touring as it is for city riding and just looking at!
