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).
