We handle several brands of chain (Chinese, Japanese and Renold). We have plenty of experience with, and access to supplies of, Renold chain. Some years back Renold changed how they distributed motorcycle chain. Because the market for the typical sizes was so small they started only supplying Velocette Motorcycle Co. in the UK. They did this with him buying a huge amount of bulk chain. As a distributor I used to be able to buy it from the US branch of Renold, I now have to buy it from Velocette. It wasn't a problem because we get a lot from him any way. This upset a lot of people who had direct accounts with Renold.
So is Renold marking their "Chinese" chain "Made in Germany?" You think, I doubt it!
So is someone buying industrial chain and selling it for motorcycles. No, they wouldn't do that.
