This document is the Maintenance Instructions for the BMW K 1200 LT motorcycle, published in June 2007 as the 4th edition. It provides essential information for the upkeep and care of the motorcycle, ensuring its safety, reliability, and value.
Function Description:
The BMW K 1200 LT is a water-cooled inline four-cylinder engine motorcycle, longitudinally installed, with 4 valves per cylinder, bucket-type tappets, two chain-driven overhead camshafts, and wet sump lubrication. It features a single-plate dry clutch with over-centre action diaphragm spring and starter ring gear, hydraulically actuated. The gearbox is a claw-shift with integral torsional vibration damper, offering 5 forward gears and a reverser. The secondary drive to the rear wheel is by a shaft protected within a hollow swinging arm of Paralever rear suspension, with integral torsional vibration damper and two universal joints. The rear wheel drive uses a crown wheel and pinion with Palloid teeth, running in anti-friction bearings, with the rear wheel directly flange-mounted to the rear of the crown wheel. The motorcycle is equipped with a digital electronic engine management system and a high-power ignition system.
