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.

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 LMAR8A-9 (sold individually). Make sure they’re gapped to 0.9mm with an appropriate spark plug gapping tool.

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.

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!
