Dirt Bike Track in Beijing

After a short holiday my friend and I had another weekend trip to 温泉区. The track is repaired! :) Well, at least there are no 40cm grooves anymore.
So on the second round I tried a little more gas and at the last jump I got a little more air than usual. It felt like 3m, but my friend claims it was around 50cm. :riding:
Anyways, while I was landing on the flat table there was a disturbing sound. Crrrumm! I rolled down the table, but I noticed the bike didn't feel right anymore. When I came to stop, I noticed that the seat was a little lower than usual. Ok, long story short, the suspension mounting at the swing arm broke off.
There are two theories now: either I am over-weight (maybe just a liiiiiittle bit: 180cm, 80kg) or the quality of the CQR parts is just bad. (I think it's the latter. ;-) )
So here are pictures:

Looks like a chopper now...

Internet research for "ＣＱＲ　平叉　断" revealed that I am not the first person to experience this problem. One Taobao-Seller told me that there have been swing arms from Zhejiang province, which tend to break. The ones from Chongqing wouldn't break. He also mentioned that the quality swing arms have this little mark:

But:
- my bike was bought from a seller in Chongqing
- Taobao sellers are not famous for their honesty
- I might be a little over-weight ;) (started eating salad again)

Anyways, I still have to repair my baby. Then see what happens next time. I still have the number of the 面包车-guy who brought my bike back to Chaoyang for 200 RMB...

Just wanted to share this experience and soften my pain.

Well, I'm finally settled in Beijing. We are excited to start riding. We plan to head to the mx track you mention above. We dont have bikes yet, but will take the RCs with us.

Welcome to Beijing!
I won't be at the track this weekend, but next Sunday I'll definitely be there. See you!
