Insurance is based on RISK. You have already shown your a BAD risk, (2 speeding tickets), in your cage, (which presumably is NOT a high performance luxury sports car).
So now your going to call your insurer and advise you want to a high performance sport bike, (with more than enough power to get into S172 territory in first gear). Your hoping they will ignore the proven fact that your prone to exceeding the limit in your car, but your GOING to behave on an R6?...LOL
Not going to happen. Stop trying to justify the purchase on seat height, etc. You WANT the R6 because you THINK it will make you a badass.
Being a former copper, I can tell you, your too immature, (based upon your driving history), to handle an R6. It may very well get you one of two things...
DEAD, or unable to ride after getting dinged for S172.
As a few MUCH wiser and experienced riders have recommended, STAY with the 500 until you learn to control your urges for speed. Then get the bike YOU want, most likely after your 25. I know at your age that seems like an eternity, BUT in those 3 years you can hine your riding skills and become a rider worthy of an SS
