Modern Vespa

Hello,

Im going to change the steering bearing, looks like it develop a notch and wandering at low speed.
Does anybody know the dimension of these bearing? I plan to get a high quality bearing/race instead of the Pogo cheese.

Thanks for your time!

Hi mate, I would recommend to send it to a dealership, as this is a major maintenance and you rely your life on the scooter, you may miss something while doing it yourself (not doubting your ability but mistakes do happen) and they you will get hurt if riding on high way at high speed.
Just to think about it,
You can download the parts manual from the internet which should show and give the specs of the parts (I think so),
Good luck,

oem bearings are fine, the procedure and proper torque is a must follow to the T. doing it yourself is totally doable and I have done a couple of them for folks. It not as bad as some folks think it is ^. just time consuming.

Thanks @old as dirt.
I found another post where you comment about the size in the forum, it was very good.
I did several bearing on GTS and assume the process would be the same on MP3. Also saw a service tech where the first ring is 12-14Nm and the lock ring is 20-22Nm.

Size you mentioned in the post were 32008X: MP3 tracks wonky at slow speeds

forgot I made that post.

I tried to get the bearings thru a dealer and I think the told me 2 weeks so I found a local bearing supplier company and took the the old bearing and races and got new ones, if I remember correctly.
