Sur Ron used 12 gauge spoke with a 3mm hole, and any 17"-18"-19" yes will be able to lace.. IF the rim is 36 hole and the spokes aree custom length.
yes I could easy place any different size rim. The front, Sur Ron, is 110mm x 20mm, 36 hole. " Luna Cycle" in the USA sold a 17" "supermoto" rim set once upon a time. This is just a different diameter rim. Different spoke, length.
