Just picked up my v4s last week and though less than 100Kms up, its an amazing machine! Had a '16 Aprilia RSV4 RF for a year or so prior to the Ducati, also have a F4 MV Senna in the garage.
Initial limited thoughts, the engine makes some interesting noises which I really like, dash is just brilliant and intuative, and whilst some are divided on looks - I really like it, it grows on you and becomes more interesting from a design point of view each time you look at it. The brakes are just from another planet, just fantastic feel and precision.
Very early in the ownership but I would pick it over the Aprilia from a overall preference point of view.
Still researching battery tender, thoughts on the Optimate Lithium product?
