4. Generation Cutoffs & Real-World Wrenching Gotchas

Model-Year & Chassis Generation Notes

Completely redesigned from the R 1250 GS (which took 4.0 L and filter 11427673541): the R 1300 GS places the gearbox underneath the crankshaft, increasing oil capacity to max 5.0 L with filter and requiring the new 11425B70298 oil filter.

Oil & Clutch Mechanical Engineering Note

Because the boxer oil cooler circuit opens via thermostat only at full operating temperature, checking oil cold gives a false low reading and leads to severe overfilling! Check 5 minutes after a full hot ride (MIN-to-MAX delta is 0.75 L).

Garage Wrenching Gotchas

  • Standard R 1300 GS ships factory-equipped with a 10Ah LiFePO4 lithium battery—never attach an old lead-acid desulfating trickle charger.
  • Bikes equipped with optional Adaptive Vehicle Height Control automatically lower seat height by 30 mm (850 mm → 820 mm) below 25 km/h and at stops.

5. Frequently Asked Questions (FAQ)

How much engine oil does the BMW R 1300 GS take compared to the R 1250 GS?

Yes—up from 4.0 L on the R 1250 GS, the R 1300 GS holds up to 5.0 L (5.3 US qt) with filter change. Pour ~4.7 L initially, warm up to full thermostat temperature, and top up cleanly to the sight-glass ring.

What is the factory cold tire pressure for the BMW R 1300 GS?

BMW specifies 2.5 bar / 250 kPa (36.3 PSI) front and 2.9 bar / 290 kPa (42.1 PSI) rear cold (temperature-compensated to 20°C on the TFT RDC screen).

Does the R 1300 GS shaft drive still need fluid changes?

While zero weekly chain lube is needed, drain and refill the rear bevel-gear housing with 180 ml of SAE 70W-80 Hypoid Axle Oil G3 every 20,000 km (12,000 mi).
