Engineering Highlight: The 360-Degree Parallel Twin
The 0B02 generation of the BMW F 800 GS (2013–2017) is celebrated for its unique engineering approach to engine vibration. Unlike most parallel twins that utilize a 180 or 270-degree crank, BMW utilized a 360-degree firing interval. To counter the inherent vibrations of both pistons moving in unison, BMW engineers implemented a unique third connecting rod (a balancing rod) attached to a central counterbalance weight. This allows the F 800 GS to mimic the exhaust note and smooth torque delivery of a traditional Boxer engine while maintaining a slim profile ideal for off-road technicality.
Technical Maintenance Specifications
Lubrication System
For the 0B02 chassis, maintaining oil shear stability is paramount. The system requires 2.9 liters of SAE 15W-50 oil meeting API SJ and JASO MA2 standards. Given the high-revving nature of the Rotax-built twin, using a JASO MA2 certified oil is critical to prevent clutch slippage in the wet-sump system.
Chassis and Contact Patch
The F 800 GS utilizes a 21-inch front wheel, signaling its off-road pedigree. Tire pressures must be adjusted based on load:
- Front (90/90 – 21): 2.2 bar (31.9 psi) solo / 2.5 bar (36.3 psi) with passenger.
- Rear (150/70 – 17): 2.5 bar (36.3 psi) solo / 2.9 bar (42.1 psi) with passenger.
Electrical and Ignition
The ignition system relies on NGK DCPR8E spark plugs. For optimal combustion efficiency and throttle response, the electrode gap must be precisely set between 0.8 and 0.9 mm. The electrical load is supported by a YTX14-BS battery, which is situated under the faux-tank cover for centralized mass.
Expert Editorial Review
The 2013-2017 0B02 revision brought significant refinements over its predecessor, including standard ABS and optional Electronic Suspension Adjustment (ESA). In our testing at MotoSpecsLab, the 0B02 remains the “Goldilocks” of the GS range—offering significantly more off-road capability than the F 700 GS, yet remaining much more manageable in tight trails than the R 1200 GS. The throttle mapping is notably smoother in this generation, addressing the “snatchy” reputation of the earlier 2008-2012 models.
Frequently Asked Questions (FAQ)
Q: How often should I check the spark plug gap?
A: We recommend checking the NGK DCPR8E gap every 20,000 km (12,000 miles) to ensure the 0.8-0.9 mm specification is maintained for cold-start reliability.
Q: Can I use 10W-40 oil?
A: While some climates allow for variance, BMW specifically mandates 15W-50 for the 0B02 to ensure proper protection at high operating temperatures common in adventure riding.
