hahaha, you fell twice but its a damn tough bike it feel hard twice and didnt even have any damage at all I was actually pretty impressed while riding it lol it's not as strong as the 150's but its definietly got some power for a 125 also I had raced it with my 150 I won by a fair bit...
I hope they dont ban them because a lot of people start with china's and go to japanese bikes once they know they start to like the motocross or whatever.
If the engine runs and the frame isnt bent then I guess you can just put on some new plastics and new tyres and change oil and forks and suspension but it really depends what your gonna use it for.
Try looking if their are any marking on the engine because that usually where they would put them if its just numbers it will help us identify what bike it is.
If you can try giving us what model and brand it is because if its something like a atomik, dhz, motovert or pitpro its pretty easy to get parts from the company itself.
