I'm a motorcycle dealer for the last 20 years. I left Corporate America to open a Harley store, sold it and retired, then opened what today is a 10 brand multiline store in Metuchen, NJ (Ducati, Triumph, BMW, Honda, Kawi, Suzuki, Vespa, Polaris, CanAm, SeaDoo).
For many years I rode Harleys, then BMWs, THEN in '04 I bought my first Monster, a 916 S4 . . . and fell in love. Since then I have always had a 4-valve Monster, and have had them all . . . S4, S4R, S4Rs, 1200. Right now I have both an S4R (which I like better than either the S4 or the S4Rs) and a 2017 1200.
I'm starting a new project, so my S4R is currently for sale (see
