One thing I remember about 3 years ago on chinariders.net was that several members all ordered Vivas around the same time from the Viva distributor (I think). We heard all about them for several months from the various members, but then their engines seemed to have some sort of catastrophic failure (maybe not all the members who bought them, but 3 or 4 of them). None of them ever really got their Viva back up and going, but then again, these were $900 dollar bikes, so were more or less experiments--

but like Carl stated, not enough support with parts to keep the bikes going did the company in. Funny enough, it might have been a year or so ago, a 'revived' Viva came back in business,using rebadged Shinerays (I think they were Shinerays) but didn't seem to stay in business, either.

I figure there must be plenty of rolling chassis bikes out there waiting for new crate engines from Lifan to get them back up and going. Ironically, the really cheap bikes of 4 or so years ago have gotten more pricey, and used ones are asking prices similar to new ones!
