Norton Mercury 650

⚠️ Things to consider

• Limited Power and Performance: While the Mercury 650 provided a decent amount of power for its time, it may feel underwhelming compared to modern motorcycles, especially for riders seeking high performance.
• Vibration Issues: The parallel twin engine can produce noticeable vibrations at higher RPMs, which can lead to discomfort during longer rides.
• Parts Availability: Due to its age and the relatively low production numbers, finding replacement parts for the Norton Mercury can be challenging and often expensive.
• Weight and Handling: Weighing in at over 400 pounds, the Mercury may feel heavy compared to more contemporary bikes, which can affect maneuverability and handling, particularly for inexperienced riders.
• Electrical System Reliability: The electrical systems on older bikes like the Mercury are often less reliable than modern systems, leading to potential issues with starting and lighting, especially if not properly maintained.
