I am of an age when Japanese cars and bikes began to be imported into the UK in large numbers.I am also of an age to remember the problems they suffered with rust and parts availability,but they are now products which other's are measured against,and I think Chinese products will,within a few years,be of an equal quality.
I have just bought a Leonart Spyder 125,the same as the AJS Eos in all but name,my first bike for over 35 years and whilst it is only a few weeks old,I am extremely impressed with it and for the princley sum of £3k,where else could you get a full size chopper? I have heard good and bad reviews about these bikes,most of them bad,but as usual it's generally the minority who have had problems that complain the loudest,the ones who are very happy with their bike tend not to shout about it.
Okay'it's not the fastest bike on the road,but when you choose to ride a chopper you choose to cruise around at a more steady pace rather than someone hunched over the fuel tank trying to break the sound barrier,each to their own,that's what makes us individuals.
As has been said by other's,there are many famous brands that are now manufactured or even owned by Chinese or Indian companies (Jaguar,Land-Rover,Royal Enfield) and the reason they are manufactured in China /India is simply costs.
