Bearing replacement for Piaggio ZIP 100 4t


I had a problem with my bearing crankshaft, but i confuse which bearing that suit to me, my technician on Indonesia said that 96925r is the number on Zip schematic, but on SIP it does't exist...

do you have suggestion for it? 

and my technician also said that left and right had different  size... and my bearing damage on left side (close to variator)


thanks for helping
