Suntour managed to spend tons of cash on the wrong areas and went out of business. I would assume these are Taiwanese made because I hadn't seen them before. I checked out the Suzue situation a few months ago in Osaka in a parts catalog and the shop owner told me what I said above. That being said they should still be of high quality. I think it is just minor details.. but that is regarding their standard track model. I hadn't seen these ti recently on ebay and here.
Hope I could help
