I live in Chengdu so only sure about here. There is a local series of car/bike days which are races and also some trackdays which are just hoon around days . But it is a rich mans sport here. Shanghai has track days at the old circuit Tianma which is a bit dodgy according to some . I used to ride street circuits in Nz ,places like Wanganui and Nelson and those tracks are lined with power poles and concrete walls , so the tracks in China seem ok to me.

If you get out into the countryside in Yunnan its just winding empty roads and free to ride with no cops so...
