This is the maintenance schedule with associated service intervals for the Triumph Speed Twin motorcycle, launched in 2019 as the original (modern) Speed Twin, but revamped as a higher-spec bike in 2021.
Triumph significantly upgraded its original Speed Twin in 2021. It’s still the same concept as before — a sportier standard bike than the Triumph T120, without being as committed as the Triumph Thruxton RS, with which it shares some components.
Already an attractive bike, Triumph gave it more performance (and more torque lower in the rev range), higher-spec Brembo M50 brakes, upside-down (rather than right-way-up, with gaiters like the old one), Marzocchi forks (though still not adjustable), and lightweight 12-spoked rims.

What you need to service a Triumph Speed Twin (2021+)
Even though the majority of people who own such a new motorcycle as the Speed Twin will get it serviced at a dealer, a number of people out there will be doing their own service. This guide is for you!
|Triumph||Part spec (2021+ Triumph Speed Twin)|
|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, or Mobil 1 10W-40.|
|Oil filter||Replace the oil filter every time you change the oil. Use Triumph part number T1218001. You can also use Hiflofiltro’s HF204RC (better than K&N these days).|
|Brake fluid||Triumph motorcycles need DOT 4 brake fluid (they have a clutch cable, so you don’t need fluid for the clutch).|
|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||The 2021 Triumph Speed Twin has Brembo M50 calipers. Triumph part number for the pads is T2021541.|
|Rear brake pads||Triumph part number is T2022955. Use FA214/2HH (same for many Triumph motorcycles)|
|Spark plugs||NGK code LMAR8A-9. Note they’re sold individually. Make sure they’re gapped to 0.9mm with an appropriate spark plug gap tool.|
|Air filter||The part number for the air filter is T2201122. You can also use K&N part TB-1216.|
|Cable maintenance||Protect All Cable Life is a good-quality cable maintenance product. You can also use engine oil (but it’s a bit messy)|
|Chain maintenance||A good kit to have on hand is the Motul chain care kit — including lubricant, cleaners, a brush, and so on.|

General information about the Triumph Speed Twin (2021+)
The Triumph Speed Twin 2021+ takes the same basic formula of the 2019 Speed Twin and adds more.
It’s still a “sporty” motorcycle in the Triumph Modern Classics line. It has more of an aggressive riding position than the Bonneville T120, but less of an actual sporty position than on the Triumph Thruxton RS (updated for 2020). The same can be said of spec — somewhere between the two.
It’s easiest to look at the specs of the two models side by side:
|Spec||2019-2020 Triumph Speed Twin||2021+ Triumph Speed Twin|
|Power||72.3 (97 hp) kW @ 6750 rpm||73.6 kW (98.6 hp) @ 7250 rpm|
|Torque||112 Nm (82.6 ft-lb) @ 4950 rpm||112 Nm (82.6 ft-lb) @ 4250 RPM|
|Front brakes||Twin 305mm discs, Brembo calipers||Twin 320mm discs, Brembo M50 calipers|
|Front suspension||41mm cartridge forks, RSU||43mm USD Marzocchi forks|
The 2021 Triumph Speed Twin otherwise delivers what the original did — a sporty and yet comfortable “everyday sports bike”, with an engine that’s full of character and doesn’t need you to rev it to the moon to get the most out of it.
It has handlebars, a “standard” plank seat, and a riding position that will have you enthusiastically revving without feeling like this bike is only happy when it’s leaned over, like on a superbike.
Triumph didn’t just improve the forks by adding the Marzocchi units. They also added lighter weight rims. Combined with the upside-down fork configuration, this contributes to significantly lower unsprung mass at the front, for better handling.
While the Triumph Speed Twin doesn’t have the higher power output of the Triumph Thruxton RS, Triumph did revise the engine’s internals. It has a lighter crank and an alternator built with rare earth magnets for less inertia, higher compression pistons, and modified intake and exhaust ports.
The combination of the engine mods means that even though power only got a small bump, peak power (the same) gets delivered lower in the rev range. This is a rare treat in the age of emissions restrictions!
Maintenance of the Speed Twin is much like earlier generations — 10000 mile (16000 km) service intervals where you need to check the valves and plugs, change the fluids (or on a time basis, e.g. brake fluid), and tighten everything up.
