4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
2017–2020 liquid-cooled T100 made 55 hp; the 2021+ Euro 5 update cut 4 kg via a low-inertia crank, boosted power to 65 hp, and added Brembo front brakes.
Oil & Clutch Mechanical Engineering Note
Low-RPM 900cc High-Torque twin shares Triumph spin-on filter T1218001 (HF204) and 3.4 L of SAE 10W-40 or 10W-50 JASO MA2 synthetic oil.
Garage Wrenching Gotchas
- Classic 32-spoke steel rims require inner tubes—carry tube repair gear or roadside assistance rather than tubeless bacon-strip plugs.
- Spin-on filter T1218001 sits underneath the front sump; lube the rubber seal and tighten strictly to 12 N·m so it does not weld to the boss.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the Triumph Bonneville T100 (900 HT) (2017–Present) require?
Because its wet multi-plate clutch shares engine oil with the gearbox, run SAE 10W-40 (JASO MA2) at 3.2 L (3.38 US qt) drain-only and 3.4 L (3.59 US qt) with filter (T1218001 / HF204).
How do you accurately check the oil level on the Bonneville T100 (900 HT), and what are its service intervals?
Hold the motorcycle dead-vertical on level ground 2–3 minutes after warm shutdown and verify the oil sits mid-way between the Upper and Lower marks in the crankcase sight glass—never on the sidestand. Torque the drain plug to 25 N·m with a new crush washer. Factory oil change intervals are every 16,000 km, with valve clearance inspection every 32,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Bonneville T100 (900 HT)?
Equipped with 100/90 - 18 M/C 56H front and 150/70 R17 M/C 69H rear tube-type rims (mushroom/string plugs will not seal—carry spare inner tubes), set cold tire pressures to 32 / 36 PSI (221/248 kPa) solo or 32 / 38 PSI loaded. Seat height is 790 mm (31.1 in) at 228 kg wet weight, delivering ~352 km per 14.5 L tank.
