Buy now 

Im just rebuilding an engine for the YBR 125 right now , it had a rumble on the engine , i was not 100% certain what the problem was but now im convinced its main bearing failure .

so quite an easy fix .

heres a video of the movement of the crank inside the bearing .

I use these bearings from here  bearings here  , i fitted FAG 6205C3 type bearings , FAG as they are excellent and used them a lot in my 2t bikes and C3 as these were recommended for 2t bikes when i used to work on them so should easily be ok for 4t .
