I have owned many bikes as well with the most recent being a Kawasaki Vulcan Vaquero (big V-twin) and I can tell you that the Vaquero is the first motorcycle I have EVER owned that has laid me up with a back injury! The suspension is absolutely horrible and within the first couple of months I was suffering with compression related disk issues. Four months into it and I traded it in for my 2015 F6B and have been smiling ever since! Took me awhile to get the windshield perfect and the seat perfect and most recently I completely upgraded the front and rear suspension and now it rides like it's on rails, the darkside helps too. Can't wait till next summer gets here!!
