we are talking about the 2 bearings at the front end of the swing arm connected to the frame plates?
INA Gelenklager GE 18-PB
That's what i have found in a post of mine from 2009 in the german forum.
No waranty
And i did not know how to translate Gelenklager.
My swing arm is still on its way to be repaired since that time.
Thanks for remembering me to ask when it will be ready
ciao Joachim
