No, not all Harley-Davidson motorcycles have electrical issues or require constant charging to start. While it is true that some riders have experienced electrical issues with certain Harley-Davidson models, it is not a universal problem across all their motorcycles.
Like any brand or manufacturer, Harley-Davidson has produced a wide range of motorcycles over the years, and individual models may have specific issues or quirks. However, it's important to note that Harley-Davidson has made efforts to improve the reliability and performance of their electrical systems over time.
Regular maintenance and proper care of the battery and charging system are essential for any motorcycle, regardless of the brand. This includes keeping the battery charged, checking connections, and addressing any issues promptly. If a motorcycle is not used for an extended period, the battery may discharge and require charging or maintenance. This is not unique to Harley-Davidson motorcycles but applies to motorcycles in general.
It's always a good idea to consult the owner's manual, follow the manufacturer's recommended maintenance schedule, and address any concerns or issues with a qualified Harley-Davidson technician. They can provide specific guidance based on the model and year of your motorcycle.
