Get an online insurance quote and go from there. I can't even get my feet on the pegs of an RR so its not for me. Most powerful bike I have taken for a test ride had 160 bhp much less than the RR. I loved the engine but at the end of the day I didn't trust myself enough to buy it. Ended up dropping 60 bhp but probably having more fun because I have to ride my bike rather than just sit on it and open the throttle. What you're considering is a massive jump in power and cost - are you really sure your ability is up to it after just two years?
Edit: Great advice from Scotty and WB based on real world experience.
