The BMW K 1200 GT (Internal code 0587) represents a pivotal moment in BMW Motorrad history. While its predecessor utilized a longitudinal ‘flying brick’ engine layout, the 0587 generation introduced a 55-degree forward-canted transverse four-cylinder engine. A unique engineering highlight of this model is the implementation of the Duolever front suspension, a system based on the Hossack design that effectively decouples steering forces from braking forces, virtually eliminating front-end dive during aggressive deceleration.
Technical Review: The High-Speed Gran Turismo
As the ‘Grand Tourer’ of the K-series, the 0587 was designed to bridge the gap between the raw sportiness of the K 1200 S and the luxury of the LT range. Delivering 152 hp and 130 Nm of torque, the engine utilizes a dry-sump lubrication system to allow for an ultra-low engine placement, enhancing the center of gravity despite the bike’s substantial 282kg wet weight.
The chassis is a bridge-type aluminum frame, providing immense torsional rigidity. This model also pioneered the use of the CAN-bus electrical system and optional Electronic Suspension Adjustment (ESA), allowing riders to modify damping and preload settings on the fly.
Maintenance Guide & Vital Specifications
1. Lubrication System
For the 0587 engine, precision in lubrication is critical due to the high-revving nature of the transverse four. Use only 3.5 liters of SAE 5W-40 Fully Synthetic oil. It must meet API SJ / JASO MA2 specifications to ensure the integrated wet clutch operates without slipping. Always check levels via the sight tube when the engine is at operating temperature.
2. Ignition & Electrical
The 0587 uses high-performance NGK KR9CI iridium spark plugs. These are essential for maintaining combustion stability under the high compression ratios of the K-engine. The electrical system is powered by a high-capacity Exide 12-19 (19Ah AGM) battery, necessitated by the heavy draw of the optional heated seats, grips, and xenon lighting.
3. Chassis & Tires
Stability at high speeds is dependent on maintaining specific tire pressures. The 120/70 ZR 17 front and 180/55 ZR 17 rear tires should be set to 2.5 bar (36.3 psi) and 2.9 bar (42.1 psi) respectively. Given the weight of the GT, tires with ‘GT’ specific carcass stiffening are highly recommended to prevent cupping.
Frequently Asked Questions
How often should the final drive oil be changed?
While originally marketed as ‘filled for life’, current technical service bulletins recommend changing the final drive oil every 20,000 km or 2 years to prevent premature bearing wear.
What is the significance of the ‘0587’ code?
The code 0587 specifically identifies the second-generation K-GT with the transverse engine (2006-2008), distinguishing it from the earlier 130-series longitudinal engine models.
