I have one bad bearing in my relay arm, the one that attached the lower shock mount.
Part number 93399-99919 which seems to be a special bearing in that it is concave (it swivels)
Its available here from Yamaha for $70 aust dollars. The others bearings in the relay arm are
all standard cylindrical type.
My question is why is this special bearing necessary?
And is there a non original equivalent available from a bearing company?

Thanks

try giving a bearing company the code on the bearing and see what they say

Hi Evil, That was the first idea that popped into my head. Unfortunately the bearing company here do not have cross reference lists for original motor cycle bearings, only for cars.
