I'm afraid I don't have any video's of it, but I saw one in action at Rogers Hill Raceway (Bere Regis). I can only give it good credit, the little kid on it was ripping round, keeping up with the average riders on the 125's and even taking some of the crap ones on 140's
He was a bit confused with the choke, so I stopped to help him start it halfway round the track, kicked it a couple of times, and it started, however, I couldn't here it over my 140, which was behind me. He didn't have any trouble with it, riding it pretty much non-stop all day, only stopping to tighten his handlebars first thing... It wasn't just him being a child that meant it didn't break either, his (who I assume to be his dad) went on it a few times, and was jumping it over all the jumps, clearing all of them, apart from the double up the hill, that was it's only fallback, it didn't quite have the umph to pull it up the hill and over the double, but saying that, neither did my tuned 140!
I also had a quick go round the pit area, and the gears were smooth, I even thought about selling mine for one
