I believe from your post this will be your first super sport bike. I would highly recommend the stabilizer. You will have enough to get adjusted to with just the raw power and acceleration. I am not saying you will loose control but do you even want to risk it on a new in the box SS bike? I do think the cost is a bit high but get one if you can. I see it like insurance, waste of money if you don't use it but could really save your A@@ if you do need it, which is a definite possibility since that new ride has the power to out ride your skill set!
Great bike post some pic and let us know what you decided to do!!
