I had my mindset on a 09 r1 since I've only owned a yamaha. However after trying my friends r1 over the summer I felt it was on the heavy side I knew it going to be a little heavy but not that much. I love the sound of the bike and the cornering of the bike took a session to get use to but once you get the hang of it, it's pretty nice. Now I haven't sat on the rsv4 but reading reviews on it. It seems nice like a good bike. Just wanted to get opinions on people that have an rsv or test rode one before. I'm leaning towArds rsv just because of my height and weight 5'6 and 145 lbs
