7x19 front
14x25.4 rear

Check Boca bearing to make sure.. They have a reference chart that helps.. Jammin is a picco based motor and the picco .28 has the above bearing demensions..

Default JPX .28 bearing

you can get those bearings here in ceramic

bocabearings.com/main1.aspx?p=product&id=3502&n=*ENK-148C-MX

this engine can be particularly problematic on bearings. we designed a special MX series with a slightly different internal configuration to take more loads. if you are having trouble with your stock bearings the MX bearings should fix the issue for you.

in the future you can always do a search here by make/model/engine size:

bocabearings.com/main1.aspx?p=quicksearchkit&cat=2

or browse our cross reference guide:

bocabearings.com/main1.aspx?p=showsubcat&cat=crossref&pg=2

hope that helps, let me know if you have any questions.
