I do wonder about the kv ratings, when I bought my 10.5 Xerun I worried it may lack some revs, but I'm thinking maybe the kv gets fudged as a selling point, cause mine seems every bit as good as my old SP, and I'd even say it seems smoother (the SP always felt a little course).

Either way, seriously don't go over thinking or beating up anything, at the end of the day they just work, ROAR will be the icing on a nice bit of gear.
