4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
For 2021+ Euro 5 (0G41), BMW added LED lighting, ride-by-wire throttle with automatic idle boost, an assist/slipper clutch, and switched the spark plug from NGK LMAR9D-J (2017–2020 0G01) to NGK LMAR8J-9E, while keeping the 1.7 L sump and 11428562889 oil filter.
Oil & Clutch Mechanical Engineering Note
Unlike Japanese 300cc twins that run 10W-30 or 10W-40, the high-revving DLC finger-follower 313cc single strictly specifies SAE 15W-50 JASO MA2 (Advantec Pro). Thinner oils increase cam-chain tensioner rattle and notchy shifting.
Garage Wrenching Gotchas
- The G 310 R uses a compact model-specific spin-on filter (
11428562889), NOT the larger11427721779cartridge used on BMW twins and boxers. - Because the cylinder head is rotated 180 degrees (front intake, rear exhaust), the airbox sits up front behind the steering head and requires removing the upper tank trim panels for access.
5. Frequently Asked Questions (FAQ)
How much engine oil does a BMW G 310 R take with a filter change?
Drain-only takes ~1.55 L, and oil plus filter (11428562889) takes 1.7 L (1.8 US qt) of SAE 15W-50 JASO MA2 oil, verified upright in the left crankcase sight glass.
What is the recommended cold tire pressure for the BMW G 310 R?
Set cold tire pressure to 220 kPa (32 PSI) front and 230 kPa (33 PSI) rear for solo riding, increasing the rear to 250 kPa (36 PSI) with a passenger.
Does the BMW G 310 R share oil filters and spark plugs with the G 310 GS?
Yes—both share the identical 313cc reverse-inclined engine, so oil filter (11428562889), 1.7 L SAE 15W-50 oil spec, and year-matched spark plugs are 100% interchangeable.
