Well, the closes Dax has to a sprocket with as many teeth as you suggest is either a 54 or a 48, so which would you suggest?
Magna, I'm near Bend, I couldn't drive any where more then an hour from there so if your further, you'd have to come to me, Also I can't seem to find much info on this titan xc50, plus I think the only way I could buy just a motor and the mounting plate, is if I was given a above normal deal, because I think it'll cost me more buying the parts separately then in a kit, I don't know, just a thought but I would be interested as long as the other guys on here think it might be a good idea, the oh mighty motor bike gurus.
