Triumph Street Scrambler (2021+) Maintenance Schedule and Service Intervals
This is the maintenance schedule and service intervals for the 2021 Triumph Street Scrambler, the update to Triumph’s original 2017 liquid-cooled scrambler.
The Triumph Street Scrambler is powered by a liquid-cooled 900cc parallel-twin with a 270-degree crank. It’s a slight displacement bump from the 865cc parallel-twin of the EFI Scrambler, but the more important change is the cooling — it’s liquid-cooled!
In 2017, Triumph made a number of updates to the engine, partly for emissions compliance, but also reducing maintenance requirements somewhat. From 2021, Triumph’s Euro 5 update keeps the engine intact, with peak of 80Nm at a low 3250 rpm, and peak power of 65 hp at 7250 rpm.
The maintenance schedule is very similar to that for the 2021+ Triumph Street Twin, though the specs for the motorcycle vary slightly. Most importantly, the ride style and gear are different — the Street Scrambler has a different riding position, spoked rims, and a high-mounted exhaust.

Triumph Street Scrambler Service Intervals
The Triumph Street Scrambler has 10 000 mile / 16 000 km or annual service intervals. At every service, you change the oil and oil filter, change the air filter, and do a list of checks.
The service schedule is similar to the 2016-2020 Street Scrambler, but Triumph simplified it a bit. For example, they no longer suggest you check the spark plugs at every service.
The valve service interval for the Street Scrambler is every two services, or 20000 miles / 32000 km. That’s also the point at which you change the spark plugs.
Since the Street Scrambler has a liquid-cooled engine, make sure you keep the coolant up to date. And replace the brake fluid per the schedule.
You may need to service your Street Scrambler more frequently if you ride it aggressively, e.g., if you enjoy winding roads or track days!
What you need to maintain the Triumph Street Scrambler (2021+)
Maintaining the Street Scrambler is fairly easy — it’s a naked bike with a chain drive, and you can get to all of the parts fairly easily (though removing the tank is awkward… many people just kind of twist it ninety degrees, leaving the pipes intact).
Below is a list of parts and consumables you need for maintaining your Triumph Street Scrambler.
The Street Scrambler from 2021 uses the 2019+ brake caliper with Brembo pads, so the spec is different to 2017-2018 brake pads — be careful.
|Part||Triumph Street Scrambler spec|
|Oil||Triumph 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, sold as Castrol Power RS Racing 4T 10W-40 (fully synthetic) in some countries. A high-quality alternative is Motul 300V or Motul 7100.|
|Oil filter||Replace the oil filter every time you change the oil. Use Triumph part number T1218001, which fits a lot of motorcycles. You can also use Hiflofiltro HF204RC which has a neat nut on the end.|
|Brake fluid||Triumph motorcycles need DOT 4 brake fluid (the 900cc range has a clutch cable, so you don’t need fluid for the clutch). E.g. Castrol DOT 4|
|Coolant||Triumph uses Hybrid Organic Acid Technology coolant with a 50% ethylene glycol mix. Zerex G05 is a HOAT coolant that meets this spec.|
|Front brake pads||Standard brake pads part code is: T2027565, TT2172 brake pads from Brembo. The equivalent EBC part is FA322/4HH.|
|Rear brake pads||Use original part number T2022955. The equivalent part number for EBC brakes is FA214/2HH.|
|Spark plugs||NGK code LMAR8A-9. Note they’re sold individually. Make sure they’re gapped to 0.9mm (+0.0, -0.1mm) with an appropriate spark plug gap tool.|
|Air filter||The part number for the air filter is T2201057. You can also use K&N part TB-9016.|
|Battery type||YTX12-BS (12 v, 10 AH)|

Chain maintenance on the Street Scrambler
Below are the chain maintenance items for the Triumph Street Scrambler (and all Triumph chain-driven motorcycles).
|Chain maintenance item||Every|
|Drive chain – wear check||500 miles (800 km)|
|Drive chain – lubricate (Motul chain paste)||200 miles (300 km)|
(Or after riding in rain or washing motorcycle)
If you’re using your Street Scrambler as a “Scrambler”, you’re likely to be getting the chain muddy, dirty, or wet. In these cases especially, attend to chain cleaning and lubrication more often.
When checking for wear, check for sticking parts of the chain, broken / rounded off teeth, and rust.
Triumph recommends you also regularly check the chain slack on your Street Scrambler and adjust as necessary.
How to check chain slack on a Triumph Street Scrambler
Every brand of motorcycle measures chain slack differently. For the Street Scrambler and other modern classic motorcycles, slack is the free vertical movement of the center part of the bottom chain segment.
To measure chain slack, you need a ruler (or tape measure) and nitrile gloves or a rag (to avoid getting grease on your hands). Follow the following procedure.
- Put the motorcycle in neutral, on a level service, and elevate the rear wheel with a stand or center stand if you have one fitted.
- Rotate the wheel and find the tightest part of the chain, in the middle. (The chain usually wears evenly but you might find tight spots)
- Use a finger to lightly push the chain up and down. Measure the deflection, which is the chain slack.
Target chain slack: 20-30 mm (0.8 – 1.2 in)
If it’s looser (or tighter) than this, you’ll need to adjust the slack.
How to adjust chain slack on the Street Scrambler
The procedure is similar to on many motorcycles, but of course specifics vary between brands. It’s the same as on other Modern Classics, however.
You need wrenches and torque wrenches to re-tighten the rear wheel. You particularly need a large torque wrench for the rear axle.
- Keep the motorcycle’s rear wheel elevated.
- Loosen the rear axle nut.
- Loosen the lock nuts on the left and hand side.
- Turn the adjuster bolts, usually counter-clockwise, extending the bolt “outward” to lengthen the chain and make it tighter. (Sometimes you’ll want to make it looser — in those cases, turn it clockwise / inward)
- Make sure to adjust the bolts the same amount on each side — check the markings.
- Tighten both adjuster nuts to 15 lb-ft / 20 Nm, and the rear axle nut to 81 lb-ft / 110 Nm (“very tight”).
Once everything’s tightened up, check the chain slack again.
Tyres and tyre pressure for the Triumph Street Scrambler
The Triumph Street Scrambler has spoked rims. Stock, it ships with Metzeler Tourance tyres.
|Wheel||Tyre size||Tyre pressure|
|Front||100/90-19||30 psi (2.1 bar)|
|Rear||150/70-17||36 psi (2.5 bar)|
Of course, tyre pressures are specified according to longevity and low cost, so adjust them according to your weight, ride style, and preferences.
About the Triumph Street Scrambler
The Triumph Street Scrambler is a street motorcycle from Triumph that is in a “Scrambler” aesthetic with high-pipes, a large 19-inch front wheel, and some underbelly protection.
It’s based on the same 900cc platform as other Triumph motorcycles. But with its knobby tires and high bars, you might think: this is a motorcycle you could actually enjoy on fire roads!
Triumph updated their 2021 Street Scrambler with a number of small upgrades.
At its core, the 2021+ Triumph Street Scrambler is the same basic motorcycle. It’s a roadster with a 900cc “high-torque” Bonneville twin-cylinder engine that makes 48 kW or 64 hp at 7,250 rpm. The rev ceiling is higher but it’s a significant (near 20%) power bump over the original 2017-2018 model.
Power dropped by one bhp in 2021 due to emissions restrictions, but those are barely noticeable. More importantly, the avid owner can iron them out with tuning and derestriction.
Like the Scrambler before it, the 2021+ Triumph Street Scrambler has torque from right down low. In fact, it makes 60 ft-lb (80 Nm) of torque from as low as 3,250 rpm.
In 2021, Triumph has added a range of premium touches, like an aluminium number board with an embossed Scrambler logo, new paint schemes, and a bunch of premium accessories as standard on the Sandstorm edition.
Like before, the Triumph Street Scrambler keeps its one dial gauge, a change from the previous two-gauge design in the original Triumph Scrambler EFI.
Triumph updated the Street Scrambler in a minor way for 2023, calling it the Triumph Scrambler 900.
