BMW R 90-6

⚠️ Things to consider

• Limited Power Output: The R 90/6, with its 898cc air-cooled twin engine, may feel underpowered compared to modern motorcycles, especially for riders used to higher-performance machines.
• Weight: Weighing in at around 500 pounds, the R 90/6 can be cumbersome for some riders, particularly when maneuvering at low speeds or during parking.
• Vibration: The engine can produce noticeable vibrations, especially at higher RPMs, which may lead to discomfort during longer rides.
• Parts Availability: While some parts are still available, sourcing certain components for a 1973 model can be challenging and potentially expensive due to its age.
• Lack of Modern Features: The R 90/6 lacks contemporary features such as advanced braking systems (like ABS), fuel injection, and modern electronics, which may be a drawback for riders accustomed to newer bikes.
