4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Launched in 2013 as the full-faired 90 hp evolution of the F 800 ST, pairing a single-sided swingarm with a clean, low-maintenance toothed belt drive.
Oil & Clutch Mechanical Engineering Note
Although final drive is an external dry toothed belt, the internal multiplate clutch runs wet in crankcase oil, requiring SAE 15W-50 JASO MA2 (2.9 L with HF160).
Garage Wrenching Gotchas
- Check the single-sided swingarm eccentric rear hub bearing for play during tire changes, as bearing wear skews belt tracking and ruins expensive belts.
- Wrap aluminum foil over the header pipes directly beneath the front spin-on oil filter before removal so spilled oil does not bake onto the exhaust.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the BMW F 800 GT (K71) (2013–2019) 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 GT (K71), 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 GT (K71)?
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 800 mm (31.5 in) at 213 kg wet weight, delivering ~360 km per 15 L tank.
