Triumph Thruxton RS (2020-2024) Maintenance Schedule

This is the maintenance schedule and serrvice intervals for the Triumph Thruxton RS, the update to the Triumph Thruxton 1200 R for 2020.

The Triumph Thruxton RS has an updated 1200cc “high power” parallel twin engine. It’s still a liquid-cooled DOHC 8-valve parallel twin with a 270 degree crank, but peak power is up by 8 PS to 105 PS (103 bhp), with peak torque delivered 700 rpm lower in the rev range — but a 500 rpm higher redline.

On top of that, the Thruxton RS gets higher spec brakes (Brembo M50 calipers up front), and fully adjustable front and rear suspension, with a Showa fork at the front and Öhlins twin shocks at the rear. The Thruxton RS is a genuinely sporty bike, that has as much go as it happens to have show — but it just happens to have a whole lot of show!

The maintenance schedule very similar to those for other motorcycles with similar engines in the Triumph Modern Classics, like the 2021+ Triumph Speed Twin, but the parts specs are different.

Triumph released the Triumph Thruxton Final Edition for 2024, signalling the end of the line.

Triumph Thruxton RS Service Intervals

Overall, the Triumph Thruxton RS has 10000 mile / 16000 km service intervals, much like other modern classics with the 1200 motor. At every service, change the oil and filter, and change the air filter, too.

Every 20000 miles / 32000 km, change the spark plugs and check the valve clearances. The Thruxton RS is a parallel twin, so the service is relatively easy, aside from access issues.

Triumph also recommends you check camshaft timing with every valve service.

Replace the coolant and brake fluid as specified. The Thruxton RS has a cable clutch, so you only need to keep it lubricated correctly.

Finally, make sure you regularly attend to the chain drive, particularly if you take your RS to the track.

What you need to service a Triumph Thruxton RS

Even though the majority of people who own such a new motorcycle will get it serviced at a dealer, a number of people out there will be doing their own service. Maybe you just want to do the obvious and easy stuff (or maybe you’re like me, and you enjoy it). Anyway, this guide is for you!

Here’s a list of the things you need to service your Triumph Thruxton RS.

PartPart spec for the Triumph Thruxton RS
OilTriumph recommends 10W/40 or 10W/50 semi or fully synthetic motorcycle engine oil that meets specification API SH (or higher) and JASO MA, such as Castrol Power 1 Racing 4T 10W-40 (fully synthetic) engine oil.
Oil filterReplace the oil filter every time you change the oil. Use Triumph part number T1218001. You can also use Hiflofiltro’s HF204RC.
Brake fluidTriumph motorcycles need DOT 4 brake fluid (the RS has a clutch cable, so you don’t need fluid for the clutch).
CoolantTriumph uses Hybrid Organic Acid Technology coolant with a 50% ethylene glycol mix. This is a silicate-based HOAT coolant. You can use an equivalent, like PEAK OET European Vehicles Blue. See our analysis of equivalents to Triumph HD4X.
Front brake padsThe RS has Brembo M50 calipers at the front. Part numbers for the pads are T2028925. You can also use EBC FA447HH.
Rear brake padsUse FA214/2HH (same for many Triumph motorcycles). Triumph part number for the pads is T2021541.
Spark plugsNGK code LMAR8A-9. Note they’re sold individually. Make sure they’re gapped to 0.9mm with an appropriate spark plug gap tool.
Air filterThe part number for the air filter is T2201122. You can also use K&N part TB-1216.
Cable maintenanceProtect All Cable Life is a good-quality cable maintenance product. You can also use engine oil (but it’s a bit messy)
Chain maintenanceA good kit to have on hand is the Motul chain care kit — including lubricant, cleaners, a brush, and so on.
BatteryDead battery? Grab a Yuasa YTZ10S.

About the Triumph Thruxton RS

The Triumph Thruxton RS is — like the other Thruxtons 1200s before it — the sportiest bike in Triumph’s “Modern Classic” line-up. It has the fastest motor, the best braking and suspension, and the most aggressive riding position.

So it’s interesting that it’s all that, and yet it’s not the fastest bike Triumph makes — that would be one from the Speed Triple family. But the Thruxton RS is a stylishly designed classic that refuses to be pigeonholed as an “all-show, no-go” bike — in fact, it goes pretty much exactly as fast as it looks like it can.

The Triumph Thruxton RS is powered by the 1200cc motor shared by other fast bikes in the Modern Classic line-up, like the latest Speed Twin. It’s a liquid-cooled 8-valve parallel twin with a 270-degree crank.

In the RS, the engine produces 77 kW (103 bhp) at 7500 rpm, and 112 Nm (83 ft-lb) of torque at 4250 rpm. Those figures and rev ranges mean that this is a bike that really hauls without you ever having to take it north of 10,000 rpm as you would on a sport bike.

The power and torque figures are also slightly higher than those that you’ll find in the Thruxton R. This comes via quite a few upgrades — a low-inertia crankshaft, clutch, and balance shafts, a rare-earth alternator, magnesium cam cover, high-compression pistons (the compression ratio is a not-too-aggressive 12.1:1), revised ports and a revised camshaft profile — all reducing inertia by 20%, giving the engine more ability to rev quickly. This also helps the Thruxton RS get to peak torque lower down — a rare treat in the age of emissions restrictions.

The maintenance of the Thruxton RS is easy. It’s basically a naked bike, which means you can do its relatively infrequent oil and fluid changes without having to muck around with removing panels.

The only slight inconvenience is doing a valve service, which means removing the tank. Boo-hoo! It’s only every 16000 km (10000 miles) so while not infrequent, isn’t so frequent (or complicated) that it’ll bleed you dry.

The riding gear on the Thruxton RS is advanced, stopping short of high-tech gadgetry like electronic self-adjusting suspension.

Front suspension on the RS is via a fully adjustable Showa 43mm upside-down fork, and rear suspension is via fully adjustable Öhlins twin shocks with piggyback reservoirs. Both ends give 120mm (about 4 inches) of travel.

Front braking on the RS is via Brembo M50 front brake calipers, the kind often found on superbikes of a couple of years ago (which these days are upgrading to Brembo Stylema calipers).

The 2024 Triumph Thruxton FE marks the end of the Thruxton RS line. The FE has the same spec as the RS, but with different colours.
