In 1984, BMW’s smallest and most agile boxer twin, the R 65 Monolever, arrived in the US, boasting an impressive array of premium features. The quartz headlight and pressure die-cast aluminum spoke wheels exude a sense of sophistication, while the 260mm drilled disc brakes provide confident stopping power.
The R 65’s tall gearing enables effortless cruising, making it feel like a larger 750 in the highway stretches, yet still delivers the agility and responsiveness you’d expect from a smaller bike. Meanwhile, its supple, long-travel suspension devours even the most twisting and rough roads with ease, providing a comfortable ride for both rider and passenger.
The result is a thrilling riding experience that’s both relaxing and exhilarating, perfect for the adventurous motorcyclist who craves the performance and style of a larger bike without sacrificing practicality. With its exceptional blend of comfort, handling, and feature set, the BMW R 65 Monolever is the ultimate choice for anyone seeking an unforgettable ride.
