Hi all!! After lots of reading in the forum I found out that nrg wheels maybe fit on the front typhoon fork if they are the 3hole little disk version but they don't fit on the rear typohoon drum since nrg drum is smaller than the 125 typhoon drum!! I've read somewhere else here again that gilera '98 fit perfectly front and rear, is it true? If so, what cc and also what about the speedo drive? Thanks for your help!!
