I saw those on ebay when looking for a new chain for my 1982 GS1100e. I will bet that is a Chinese made O-ring chain. I put a Chinese chain (BikeMaster?) on a Honda CB750 Nighthawk I had for awhile. No problems and nothing obviously wrong with it, but then I was planning on selling the bike after the summer, and that bike makes half the power of a Busa.
Given that a good chain and sprockets costs $250 and can last over 20-25,000 miles with proper maintenance, this is a stupid place to try to save money, especially if you plan on keeping your Busa for awhile.
