KTM 400 stock sprockets

[farmer58za]

Hi Guys
what are the stock front/rear sprocket sizes for a '75 KTM 400 GS?
Will sprockets from a later model fit?

Thanks in advance

depends on the purpose of the bike.  THe GS version had 15:48,the MC 13:50 or 13: 48,i guess. if there are needs, i have NOS ones on stock,also one made of steel. i was wondering myself who made them of steel,but they will hold on 5 times longer than the aluminium ones do.
