Yamaha OEM wheel sprockets that fit TWs

Digging around some old files I found this list of Yamaha OEM wheel sprockets that will fit the TW wheel hub. I've always had good service from OEM Yamaha sprockets and pricing from online sources is usually competitive with aftermarket. I don't remember how I figured what would fit and what wouldn't--probably went to an aftermarket suppliers engineering drawings and compared the bolt circles and chain size to develop a list of bikes with the same parameters. Anywho, the tooth count is the last 2 digits of the second set of numbers; i. e., 248-25445-10-00 is 45T. 248-25451-10-00 is 51T. If memory serves, in those instances where a number has been superceded, both the old and new numbers are listed. Some sprockets are black, some are silver--depends on year on some models. The following tooth counts are available from Yamaha: 42, 44, 45, 47, 48, 49, 50, 51, 53, 55. I've eyeballed several of these numbers side-by-side and not yet found any fitment problems, but be sure to double check before plunking your money down.
