4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Chain-driven K73 roadster distinguished from belt-driven F 800 S/ST; major 2015 update replaced the asymmetric headlight and telescopic fork with USD forks, radial Brembos, and 90 hp.
Oil & Clutch Mechanical Engineering Note
Rotax 798cc semi-dry-sump twin taking 2.9 L of SAE 15W-50 JASO MA2 with spin-on filter HF160 and a 40 N·m sump drain plug torque.
Garage Wrenching Gotchas
- Fuel fills at the right rear tail panel while the front faux-tank cover houses the YTX14-BS battery and airbox for effortless top-access maintenance.
- Backlight the dark plastic coolant expansion reservoir with a flashlight on the right side to accurately read the MIN/MAX coolant marks.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the BMW F 800 R (K73) (2009–2019) require?
Because its wet multi-plate clutch shares engine oil with the gearbox, run SAE 15W-50 (JASO MA2) at 2.7 L (2.85 US qt) drain-only and 2.9 L (3.06 US qt) with filter (11428562889 / HF160).
How do you accurately check the oil level on the F 800 R (K73), and what are its service intervals?
Hold the bike upright on level ground 2–3 minutes after shutdown, wipe the dipstick, and rest it on the filler threads without screwing it in (threading it in reads artificially high and risks oil starvation). Torque the drain plug to 40 N·m with a new crush washer. Factory oil change intervals are every 10,000 km, with valve clearance inspection every 20,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the F 800 R (K73)?
Fitted with 120/70 ZR17 front and 180/55 ZR17 rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 36 / 42 PSI (250/290 kPa) solo or 36 / 42 PSI loaded. Seat height is 790 mm (31.1 in) at 202 kg wet weight, delivering ~345 km per 15 L tank.
