4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Early 2017–2020 base Bobber had a 9.1 L tank and 19-inch single-disc front; 2021+ standardized the 12 L tank, fat 16-inch front wheel, and twin Brembo discs.
Oil & Clutch Mechanical Engineering Note
Dedicated low-end Bobber camshaft tune produces 106 N·m at 4,000 rpm; service with 3.4 L of SAE 10W-40/10W-50 JASO MA2 and filter T1218001.
Garage Wrenching Gotchas
- Dual-chamber airbox design under the floating solo seat pan uses TWO separate air filter elements—replace both left and right filters together.
- Spoked 16-inch fat wheels require inner tubes despite tubeless-rated tire carcasses, and the homologated solo chassis cannot carry passengers.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the Triumph Bonneville Bobber / Bobber Black (1200) (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 Bobber / Bobber Black (1200), 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 Bobber / Bobber Black (1200)?
Equipped with 130/90 B16 M/C 73H front and 150/80 R16 M/C 71V rear tube-type rims (mushroom/string plugs will not seal—carry spare inner tubes), set cold tire pressures to 32 / 38 PSI (221/262 kPa) solo or 32 / 38 PSI loaded. Seat height is 690 mm (27.2 in) at 251 kg wet weight, delivering ~256 km per 12 L tank.
