searay175 Posted December 30, 2009 Report Share Posted December 30, 2009 Has anyone researched what the bearing and race #s are to upgrade to tapered bearings in the headstock of a ty250? If they are a common size that is available at a auto parts house I would not have to wait on shipping. Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 30, 2009 Report Share Posted December 30, 2009 TY250 what? Tapered needle roller bearing sets for TY250 twinshock are available as an aftermarket part for about $50 from motorbike shops everywhere and on eBay. For TY250 mono or TY250Z I have no idea what is available Quote Link to comment Share on other sites More sharing options...
searay175 Posted December 30, 2009 Author Report Share Posted December 30, 2009 Sorry! TY250C. I've seen all of them on the web, just thought if they were a somewhat common bearing set that I could pick them up locally. Thanks! Quote Link to comment Share on other sites More sharing options...
stork955 Posted December 30, 2009 Report Share Posted December 30, 2009 Gday, they are an unusual (non ISO) size. Go with the Feetups' previous post - see your local bike shop. The TY's use a very common Yamaha neck bearing set, readily available and the only way to go. I like All-Balls kits as they come with all the necessary seals as well.

searay175 Posted December 30, 2009 Author Report Share Posted December 30, 2009 Thanks for the info! Just thought I would throw it out there just in case! Quote Link to comment Share on other sites More sharing options...
alan_nc Posted December 31, 2009 Report Share Posted December 31, 2009 Searay, My guess is you are correct, they probably are an "off the shelf" item. Take a set of calipers to one and check the Timken or other bearing site. If I remember correctly we found that the main bearings and seals where stock items.
