with SM pro's you have to buy new spokes since the holes in rims are way too big for stock suzuki spokes. I got SM pro front rim for my 79 Rm 125 and to my surprise it was not actually custom drilled. just modified rim that is normaly used on modern bikes. Buchanan in US will actually drill a blank dimpled or non dimpled rims to suit your bike. You can ask them to drill holes(diameter) to suit your spoke nipples. They will charge about $200 per wheel(EXCEL Rim) plus shipping.
