This comprehensive service manual provides workshop-grade coverage of every system including oilhead engine overhaul, 4-valve head adjustment, Telelever suspension service, Paralever swingarm bearing replacement, final drive backlash shimming, ABS-II brake diagnostics, Motronic fuel injection troubleshooting, and complete electrical schematics. Essential for professional technicians and BMW enthusiasts maintaining these groundbreaking motorcycles.
1993-2001 BMW 1 Series R1100 R1100RT R1100RS Service Repair Workshop Manual PDF
The BMW R1100 series, introduced in 1993 with the R1100RS, represented a revolutionary departure from BMW Motorrad's traditional airhead boxer engine design. The new oilhead engine featured a 1,085cc air/oil-cooled flat-twin with 4-valve cylinder heads, electronic fuel injection via Motronic engine management, and significantly improved power output compared to the aging 2-valve airhead. The R1100RS sport-tourer was the first model to receive this engine, followed by the R1100RT (touring), R1100GS (adventure), and R1100R (roadster). The oilhead's distinctive exposed cylinder heads with oil cooling fins allowed higher compression ratios and better heat dissipation than air-cooled predecessors, enabling sustained high-speed touring without the oil temperature issues that limited earlier BMW twins.
The Telelever front suspension system was another BMW innovation on the R1100 platform. By locating the suspension's steering pivot separately from the damper unit, BMW virtually eliminated brake dive and improved steering geometry under hard braking. The.Paralever rear suspension used a single-sided swingarm design that minimized shaft drive jacking effect, a well-known characteristic of traditional shaft-drive motorcycles. The R1100GT chassis used a tubular steel spaceframe that was both lighter and more rigid than the double-loop frames of previous generations. The combination of oilhead power, Telelever/Paralever suspension, and modern chassis geometry gave the R1100 series handling characteristics that surprised many observers accustomed to BMW's traditional touring image.
VEHICLE/EQUIPMENT INTRODUCTION:
The BMW R1100 series (1993-2001), encompassing the R1100RS, R1100RT, R1100GS, R1100R, and R1100S, introduced BMW Motorrads revolutionary oilhead flat-twin engine with 4-valve cylinder heads, electronic fuel injection, and air/oil-cooled architecture. The 1,085cc boxer engine was paired with BMWs innovative Telelever front suspension (eliminating brake dive) and Paralever rear swingarm (minimizing shaft jacking) within a tubular spaceframe chassis. The R1100RS pioneered the platform as a sport-tourer, while the R1100RT offered full touring fairing and weather protection. The Motronic MA2.2/MA2.4 engine management system controlled fuel delivery and ignition timing with adaptive learning. This manual provides comprehensive factory service coverage for the complete R1100 oilhead range from 1993 through 2001.
