yea it's not bad, easy to ride and fairly reliable.... good little paddock basher.
you'd be better off with an atomik nitrous tho, $150 cheaper and it's pretty much the same bike, has better exhaust and swingarm plus a few other better bits I can't remember.... plus you can choose between 125cc/140cc/150cc/160cc for the same price.
for a beginner rider I suggest you get the 140cc Nitrous. If you plan to ride at at a MX track then you should look at saving some more $ and getting a pitster pro
