Yamaha WR290R(X) supermoto'd

Here's a video of my first ride yesterday on the WRR with supermoto wheels.
I had the gearing setup at 13X54 in this video and top speed was still 85+MPH.
My speedo is off in this video because I was still playing around with the gearing and did not correct it yet with the speedohealer. I think at 85 on speedo the GPS said 76.

I'm still not sure what gearing I'll end up with as I'm still playing with it.
