Some owners report vibration at specific RPMs, typical for large V-twins.  Rear brake pad wear can be accelerated due to its size and use.  Proper maintenance of the liquid cooling system is crucial.
        
     
    
        
            Specific Maintenance Focus:
        
        
            Diligent adherence to the service schedule, especially for the charging system and coolant, is vital for long-term reliability.  Regularly check tire pressures, particularly the wide rear tire, for optimal performance and safety.
