4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Launched in 2016 as Street Twin (55 hp), upgraded to 65 hp and Brembo caliper in 2019, renamed Speed Twin 900 in 2023, and given USD forks + IMU for 2025.
Oil & Clutch Mechanical Engineering Note
Torque-assist wet clutch maintains feather-light lever effort when serviced with 3.4 L of SAE 10W-40/10W-50 JASO MA2 and spin-on filter HF204.
Garage Wrenching Gotchas
- Unlike wire-spoke T100/T120 models, cast alloy wheels take standard tubeless tires—making roadside plug repairs straightforward.
- On 2016–2018 Street Twins, verify the headstock main-harness routing recall guide clip was installed so full-lock turns do not chafe ignition wires.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the Triumph Speed Twin 900 (Street Twin) (2016–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 Speed Twin 900 (Street Twin), 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 Speed Twin 900 (Street Twin)?
Fitted with 100/90 - 18 M/C 56H front and 150/70 R17 M/C 69H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 32 / 36 PSI (221/248 kPa) solo or 32 / 38 PSI loaded. Seat height is 765 mm (30.1 in) at 216 kg wet weight, delivering ~294 km per 12 L tank.
