My experience over the past 10 years of dealing with India / Taiwan /and now China is that in the main quality has improved significantly on MOST parts.
That said - anything that requires close tolerances / quality material - of a mechanical nature is still way behind.
Metal bashing and casting - The Indians seem to have a good handle on that. I bought a batch of alloy Monza gas caps - they were made to an English pattern and are pretty good. Castings are not porous and the finish / polish is also good. My pal has imported a batch of steel and alloy "replica" tanks. Quality has been good, finish just about OK - you take the word "replica" loosely ! More like "similar to".
. Ditto with Replica Lucas 7" headlamps - price excellent and pattern spot on, but be prepared to repaint or rechrome the shells if you want an original type finish.
Also bought some alloy Chinese clip-ons - again pretty good quality and finish and good prices [ obviously ]. NO comparison with Tarozzi - but 40% cheaper.
Anything in the rag trade is generally pretty good - as they make for most Western companies anyway !
The shox have been getting a bad press here in the UK where they've been available for a little over 2 years now. Initially they LOOK the part, but are just not lasting and giving consistent performace.
As a rule of thumb - I'm steering clear of parts that are of a built up [ mechanical ] nature for the time being.
