Electrical Concerns:
Older wiring harnesses can degrade, and connectors may corrode, leading to intermittent electrical issues.
Tire Pressure:
Refer to manual for specific front and rear tire pressures, which vary based on load and riding conditions.
Battery Type:
Typically a 12V, high-CCA motorcycle battery (refer to manual for exact specifications and terminal orientation).
Fuel System Concerns:
Potential issues with fuel injectors or pump depending on maintenance history and fuel quality.
Brand Origins:
Bayerische Motoren Werke AG (BMW), German manufacturer with a long history in aviation engines and automotive production, extending into motorcycles in the early 20th century.
K Series Development:
The K1100 is part of BMW's K-series, introduced in the early 1980s. It represented a significant departure from BMW's traditional air-cooled flat-twin boxer engines, featuring a transversely mounted inline-four engine with a stressed-member chassis. The K1100 was an evolution of the K75 and K100 models, offering increased displacement and performance.
K1100 Variants:
K1100LT (Luxus-Touring) focused on comfort and touring, featuring a large fairing, comfortable seating, and luggage; K1100RS (Rennsport) offered a sportier riding position with a more compact fairing.
K1100 Production Years:
1992-2000 (approximate, with the K1100LT and K1100RS being the primary variants).
