BMW R 1100RS (1997 -98)

BMW R 1100RS (1997 -98)

The BMW R 1100RS is a game-changer in the world of touring motorcycles. With its air-cooled, four-stroke, horizontally opposed Boxer engine, this bike boasts a significant upgrade over its predecessors, featuring four valves per cylinder and electronic fuel injection. Gone are the days of traditional push-rods, as the R 1100RS now employs a series of belts driven from the crankshaft to actuate its camshafts.

The introduction of the “Telelever” front suspension system is a major innovation, addressing the long-standing issue of fork flex and compromised steering geometry under braking. This clever design keeps the steering and suspension systems separate, resulting in a smoother, more controlled ride.

With its shaft drive and Paralever swingarm, the R 1100RS is built for comfort and stability on the open road. And with BMW’s reputation for building top-quality touring motorcycles, it’s clear that this bike is designed to deliver an exceptional riding experience.
