I think yamaha needs to bring the Ovation back with a few tweaks, would be head on competition for that DOO. Let see, Ovation + Longer travel Pogosticks + short version of the RS pro-active (I think the Ovation was a 109" track) + a 450cc 4stroke out of the YZ450f!!! sounds like a nice little sled to me, and its a four stroke that revs plenty good to use with CVT clutches.
