This is the maintenance schedule with associated service intervals for the Triumph Bonneville T100 motorcycles made from 2021+ to conform to EURO 5 specification.
The Bonneville T100 (2021+)’s maintenance schedule is an evolution of the pre-2021 Bonneville T100. It shares the same basic block, but a number of parts were upgraded, not the least of which was the engine, which is now 10 PS (9 hp) more powerful.
The engine is still a 900cc liquid-cooled parallel-twin engine with a 270-degree crankshaft. After the power upgrade, performance is similar to its stablemate, the 2019-2020 Street Twin.
The new 2021+ Bonneville T100 also got Brembo front brakes, plus a higher-spec cartridge front fork.

What you need to service the Triumph Bonneville T100 2021+
Servicing the Bonneville T100 is a lot like servicing the previous generation T100. After all, they’re very similar motorcycles (same engine base) — just different in terms of engine performance.
|Part||Triumph 900cc Bonneville T100 (2021+)|
|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 7100.|
|Oil filter||Replace the oil filter every time you change the oil. Use Triumph part number T1218001, which fits a lot of Triumph 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).|
|Coolant||Triumph uses Hybrid Organic Acid Technology coolant with a 50% ethylene glycol mix. Zerex Asian Vehicle Coolant is a HOAT coolant that meets this spec.|
|Front brake pads||Standard brake pads code is T2026565 (for the Brembo caliper). The part number for EBC brakes 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.|

About the Triumph Bonneville T100
The Triumph Bonneville line is a long-standing brand within Triumph’s range. It’s the “relaxed standard” motorcycle made by Triumph.
Calling it a “naked bike” would be a disservice, because the Bonneville wouldn’t dream of having fairings, so comparing it to street-tuned sportbikes — even vintage-styled ones like the Yamaha XSR900 — would not work.
In 2017, Triumph updated their Bonneville T100 line, updating the 865cc air/oil-cooled engine to the new water-cooled “high torque” 900cc engine. In 2021, Triumph updated the Bonneville again, this time making it Euro 5 complaint.
But at the same time, Triumph updated the Bonneville T100’s engine, giving it a power bump. Power is now up to 64 hp from the previous 55, matching the power bump that the Triumph Street Twin and Street Scrambler received in 2019.
The engine is a gem. It’s a liquid-cooled 900cc parallel twin with a 270-degree firing order. It has lots of torque down low and revs quite well past 6,000 rpm, making it fun to ride at all kinds of speeds (as long as they’re well below racing track speeds).
Since 2021, the Bonneville T100 has become much closer in spec to the Street Twin. The engine performs very similarly, and the chassis is lighter. However, the chassis is still a lot heavier (15 kg or 33 lb) than the one in the Street Twin — the price you pay for style (and comfort).
Other aspects of the Bonnie T100 have stayed the same. It still has a single front disc, a comfortable riding position, and twin gauges.
