The zx14r is more sport than tour The Concours is more tour than sport (IMO)   14r has better brakes, suspension, is less comfortable, weighs a couple hundred pounds less, and has about 40-50 more HP.  Completely different bikes if you ask me.  The 14r handles extremely well for a 500lb bike.  Unbelievably well actually.   Im switching because I want to go back to 1 bike and I want something relatively cheap, handles well, fairly comfortable for longer rides, looks good, and sounds good...more unique than an inline.  The Sprint checks all those boxes.  I am done with inlines for no reason other than I am bored with them.
