This is alot like an oil thread, asking opinions every one has one and a good case for and against. I think it is a personal choice that needs to be addressed by ones riding habits, funds and how much you will be willing to do to your bike on your own. Personally I ride my bike every day, I chose to not own a car, I do not like surprises, it gives me peace of mind, as a matter of fact I will be taking mine in next Tuesday for its 3rd front master cylinder and new front rotor and motor mount All on ESP:s
