Triumph Bonneville T100 (2017-2020) Maintenance Schedule
This is the maintenance schedule with associated service intervals for the Triumph Bonneville T100 motorcycles made from 2017-2020 (announced in late 2016).
The Bonneville T100’s maintenance schedule is very similar to those for other motorcycles with similar engines in the Triumph Modern Classics with the same engine.
The Bonneville T100 is an evolution of the previous generation of Bonneville T100 which had an 865cc engine. The 2017-2020 Triumph Bonneville T100 is based on the same platform as the original 2017 Street Twin, with a 900cc parallel twin water-cooled and fuel-injected motor with a 270-degree crank.
The 2021+ Bonneville T100 was updated for EURO 5 regulations, with the engine re-tuned significantly, closely matching the new Street Twin.

What you need to service the Triumph Bonneville T100 (2017-2020)
Servicing the Bonneville T100 is a lot like servicing the Street Twin. After all, they’re very similar motorcycles (same engine base) — just different in terms of chassis.
| Part | Triumph 900cc Bonneville T100 (2017-2020) |
|---|---|
| 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 T2027535. The equivalent part number for EBC brakes is FA181HH. |
| 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. |

General information about the Triumph Bonneville T100
In 2017, Triumph updated their Bonneville T100 line, updating the 865cc air/oil-cooled engine to the new water-cooled “high torque” 900cc engine.
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. They’re for different markets.
The Bonnie T100 is quite different to the Street Twin with which it shares an engine block. Here are the key differences:
| Spec | Triumph Street Twin (2019-2018) | Triumph Bonneville T100 (2017-2020) |
|---|---|---|
| Compression ratio | 11.0:1 | 10.55:1 |
| Peak power | 48 kW (65) hp @ 7,500 rpm (2019-2020) | 40.5kW (55bhp) @ 5900rpm |
| Peak torque | 80 Nm @ 3,800 rpm | 80 Nm @ 3,200 rpm |
| Riding position | Comfortable/sporty | Comfortable |
| Dry Weight | 198kg | 213kg |
| Braking | Single 310mm disc, Nissin 2-piston floating caliper | Single 310mm disc, Nissin 2-piston floating caliper |
| Ride gear | Single dial (no tacho) | Twin dial (inc. tachometer) |
| Wheels | Cast | Spoked |
The Bonneville T100 is closer to the T120 (with the larger engine) than the street twin. It’s a relaxed motorcycle, but lighter than its bigger sibling. Having a smaller engine doesn’t make it a weaker feeling motorcycle — it’s a revvier engine and riding it can be a more engaging experience, depending on how and where you ride.
In 2019, Triumph upgraded the Street Twin’s engine, separating it from the Triumph Bonneville T100’s in terms of performance, and changing a couple of chassis parts.
In 2021, Triumph upgraded the Bonneville T100’s engine too, with some changes to the maintenance schedule. You can see the Bonneville T100 2021+ maintenance schedule here.
