I'm 5'9 and 240......you should see me on an Ohvale....seen the WTF face on pit lane more than once as I come rollin' by. I finish last in most of my races, but I don't care. I'm having a blast and it's good learning time to improve my riding overall. Mini's have definitely dropped my lap times when I get back on my R1. But damn does the R1 feel like a tank in the transition.
