Mozo USA are I suspect Taiwanese on a par with Sync, RST, Balistic and even Zoom. The USA bit is just to cash in on the USA's involvement in mtb development.
Found an ebay add for Mozo R200 forks which may be the latest development in the series:http://www.ebay.ca/itm/MOZO-USA-R200-26 ... 0732690651
If they're Aluminium or Magnesium that suggests thy're from the upper end of low end forks and I suspect on a par with RST's who were producers of good quality low end forks. MIght even be rebadged RST's since RST Mozo's are a fork model in its own right. Probably perfectly serviceable forks just lacking in the cache' of the big boys but nothing to write home about.
