The BMW R1200RT, R1200ST, and R1200GS models produced between 2004 and 2005 represent a pivotal moment in BMW Motorrad's history, marking the transition to a new generation of boxer-engined motorcycles. These models were lauded for their innovative features, advanced technology, and exceptional performance, solidifying their position as high-performance tourers, sport tourers, and adventure motorcycles, respectively. Sharing the same fundamental engine and chassis, these machines offered distinct riding experiences tailored to their specific purpose. The R1200RT, with its full fairing, spacious luggage compartments, and comfortable rider ergonomics, was designed for long-distance touring, providing a refined and luxurious ride. The R1200ST, on the other hand, embraced a sportier approach with its half-fairing, aggressive riding posture, and performance-oriented suspension, offering a thrilling blend of sportiness and touring comfort. The R1200GS, true to its adventurous nature, boasted a rugged design, high ground clearance, and long-travel suspension, enabling it to tackle diverse terrain and off-road challenges.

These models were powered by a new, liquid-cooled 1170cc boxer engine, known for its smooth power delivery, impressive torque, and fuel efficiency. The engine featured a revised cylinder head design, optimized intake and exhaust ports, and a revised camshaft profile for improved performance and throttle response. Another notable feature was the introduction of BMW's Electronic Throttle Control (ETC), which electronically linked the throttle twist grip to the engine management system, offering smoother power delivery and enhanced fuel efficiency. The chassis also underwent a significant evolution, incorporating a newly designed aluminum frame for improved rigidity and handling. The front suspension featured a telescopic fork, while the rear suspension was a Paralever swingarm with a single-sided shock absorber. Advancements in braking technology introduced ABS as a standard feature, enhancing safety and control. These technological innovations, combined with their inherent versatility and performance, made the 2004-2005 R1200RT, R1200ST, and R1200GS not only highly sought-after models but also significant milestones in BMW Motorrad's legacy.
