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.
Product | Image | Description |
---|---|---|
Oil | ![]() | The 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 filter | ![]() | Replace 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 plugs | ![]() | Use NGK spark plugs with code LMAR8A-9 (sold individually). Make sure they’re gapped to 0.9mm with an appropriate spark plug gapping tool. |
Air filter | ![]() | Use Triumph part number T2200987 or K&N equivalent part TB-6713. |
Coolant | ![]() | Triumph uses Hybrid Organic Acid Technology coolant with a 50% ethylene glycol mix. Zerex G05 is a HOAT coolant that meets this spec. |
Brake pads | Front: Triumph part T2021978 (you need two sets) Rear: Triumph part T2022458 (one set only) |
You may also need the following general consumables for servicing your Triumph Rocket 3.
Product | Thumbnail | Description |
Chain lubricant | ![]() | The chain needs to be lubricated every 800 km/500 miles (or more, if it gets wet/dirty). Motul chain paste is cheap and well-loved. |
Chain cleaner brush | ![]() | A chain cleaner brush makes cleaning off grime and then distributing new lubricant much more easy. |
Paddock Stand — Single Sided | ![]() | Lubricating the chain and changing the oil both become a lot easier once you use an affordable paddock stand (for motorcycles with a single-side swing-arm). |
Cable lubricant | ![]() | Remember 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. |
Grease | ![]() | Get a good lithium soap based grease for lubricating major components like your side stand, centre stand, and bearings. |

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!
