Yeah the YZ125 seemed pretty good as a 125,it screamed but did so pretty smoothly,came on the pipe and just kept pulling with out doing anything real abrupt,the one I rode had a small flywheel weight added on,I dont know if that's better or worse, but the thing felt like riding a full sized mini bike somehow.
Tiny little engine.
I wonder how long a piston kit would last trailriding?
