I'm exactly the same! Had S4R 2005 from 2012 until 2018, then traded it in for a Harley Davidson. Worst mistake in my biking life! Went back to Ducatis a year later, traded in the HD for the 2017 Ducati Supersport, but was missing the monster so much, bought a 2006 S4RS at the end of last year. Spent quite a few hours and quite a few coins on making it just right and have already put over 1,500 miles on it from Feb to May, then got a knee injury, so just getting back to it now
Which is a lot for me. Kept the Supersport for now as it's a lot smoother and supposedly more reliable, but I think she'll have to go at some point as I don't ride her at all.
