I'm not sure anyone will know, but it's worth a try. Does anyone know if a 99-02 sv650 yoke nut has the same thread as the yoke nut from an 04+ model?

From 2002 to 2003 the stem, stem nuts and top nut all have different part numbers.
However, many other Suzuki share the 03 parts and some share the 02.

Which year are you chasing and are you after the roller play nuts or the top yoke retaining nut?

It's a yoke retaining bolt for an 09 Sv I'm looking at, despite having a different style aesthetically, the thread has thankfully remained, both use the same pitch as well as having the same depth, so my worries are over.

'appi daze!
