If you have the OEM plastics, you can do a pretty good job of repairing and refabricating some of the broken parts with the ABS shavings/powder and acetone. They do sell kits such as Plastex that are the same thing, in a nice convenient package. It even comes with a molding strip, that you can heat up and shape to reform broken tabs, etc. I don't think new OEM Honda plastics are even available anymore, and the people selling whatever stock they have are charging $$$.

The Chinese bodywork is a mixed bag from what I've been able to find. Granted most, if not all the opinions I've read about it are not NSR kits. A lot of the newer bikes have pretty complicated parts and pieces so I can see there being less room for error in the fitment (which is a huge complaint). The NSR kits are 7 pretty large pieces from what I can tell, so I'd guess that fitting would be a lot easier, even if you had to tool it a bit. I can't say about the quality of the paint jobs on these kits though. I've heard that the kits are made to order, which would explain some of the lengthy shipping times as well.
