The BMW R 1300 GS 0M21-719 represents a paradigm shift in adventure motorcycling, most notably for its Evo-Telelever front-end suspension. Unlike previous iterations, this system utilizes a flexible element (a stainless steel plate) to decouple steering forces from tilting movements, offering unparalleled precision and feedback that was historically a weakness of the Telelever design. This engineering milestone allows the Tramuntana to maintain the anti-dive characteristics of a traditional GS while providing the steering feel of a conventional telescopic fork.
Engineering Overview: The 0M21-719 Platform
The Option 719 Tramuntana is not merely an aesthetic package; it is built on the most compact Boxer engine BMW has ever produced. By placing the gearbox underneath the engine and integrating the camshaft drive, BMW reduced the overall engine length significantly. The Euro 5+ compliance is achieved through advanced knock sensor technology and a sophisticated exhaust system that manages emissions without sacrificing the 145 hp output.
Maintenance Guide for Professionals
Lubrication System
The R 1300 GS requires exactly 4.0 liters of SAE 5W-40 API SL / JASO MA2 synthetic oil. Given the high-compression nature of the 1300cc Boxer, maintaining oil quality is critical for the longevity of the ShiftCam actuators. We recommend checking the oil level via the sight glass only when the engine is at operating temperature and the bike is on its center stand.
Electrical & Battery Management
Equipped with a 12 V, 10 Ah Lithium-ion (LiFePO4) battery, the 0M21-719 demands specific care. Traditional lead-acid chargers can damage the internal Battery Management System (BMS). Always use a BMW-approved lithium-compatible charger to maintain the cell balance, especially during winter storage.
Chassis and Tires
The 19-inch front and 17-inch rear configuration is optimized for the new sheet-metal shell frame. To preserve the handling characteristics of the Tramuntana, pressures must be maintained at 2.5 bar (Front) and 2.9 bar (Rear). Even minor deviations can impact the sensitivity of the Dynamic Suspension Adjustment (DSA) sensors.
FAQ
Q: What is the spark plug gap for the NGK LMAR9AI-10?
A: The NGK LMAR9AI-10 is a laser iridium plug; the gap is factory-set and should be handled with extreme care to avoid damaging the fine-wire electrode.
Q: Does the Euro 5+ version require different maintenance than the standard Euro 5?
A: While the mechanical service intervals remain similar, the Euro 5+ diagnostics are more sensitive to sensor variances, requiring the BMW OSS (Online Service System) for comprehensive fault clearing.
