My colleague bought United Jazba recently. I personally checked the bike and can say that its built quality is totally subpar. There was no finishing in the plastics as you can expect from United. When I got closer, I found that carburator seal was leaking where it was fixed with the engine. Later, when my colleague went to discuss this issue with the dealer, he was shocked to know that there was no seal inside :o
I tried his bike and found its shocks to be ROCK SOLID as there was no such thing as jumpers and I was just sitting on a bunch of bricks. This bike is a total crap. As, I already own a 100cc chinese bike, I am happy that it is not from United 
One more thing, I have also tried the above mentioned 100cc by United and its seat was ROCK SOLID too. United is just plain Wow
