I have done the Jap bike thing and can honestly say that as far as new bikes go, I will never buy another Japanese bike as long as Europe and America are still building them.
That said, I would buy a used one to buld into something like a cafe racer.
I fully expect China to bring out it's own line of higher quality motorbikes but they most likely will be copies of someone else's machines.
Back in 1980 I bought a new XS 650 because I couldn't find anyone who sold Bonnevilles in Norfolk, VA. and it was a bike with the same styling cues as the Trumpet. Rode the damned thing for three years and had to replace stuff all the time that either shook off (4 license plates broke in half, exhaust pipes flew off at 60 mph, drive chains left me stranded) or wore out repeately(plastic swing arm bearings) but that was in the early 80's and I know alot of things have changed since then with the Japanese makes. Many used bikes later when I was ready to buy another new bike, that Triumph Bonneville was still eating on my brain and the desire to own one was still strong. I bought one of the first EFI models sold in South Carolina and have been extremely pleased with everything about it for my two years of ownership. If it were totaled out, God forbide, I would definately purchase another.
The Orientals may be able to copy Triumph and Harley but they can't duplicate the character of the originals and it's character that makes things memmorable.
Just my 2 cents, your view may differ and that's OK
