Welcome from New Zealand....I had a Storm b4 my 2014 Roadster and I absolutely loved the Storm and found it very difficult to sell it but in saying that, I have absolutely fallen in love with the r3 to the point of buying a new one just b4 xmas. Mine is a 2016 roadster with lotsa fruit on it now. One of the most noticeable differences for me is the sitting position. On the Roadster the feet are under you which is more comfy on the tailbone area on longer rides. Of course the extra power is extra ordinary and very very addictive...if youre like a lot of us guys, we enjoy riding for what it is...RIDING!...The R3 is surprisingly nimble too but you gotta stay strong with it...it is a big bike. You will love it!
