i think part of the reason the HD 48 looks wide up front is the smaller diameter rim, its on a 16, but it has a 130/90 front tire on it. you can put a 120 bias on a stock front wheel, or a 130 radial on a 3.5" front rim. you could probably pay kosman to make a 16 x 3.5" rim for the vmax too, but that'd probably be big money, but you should be able to fit a 130/90/16 on the front then and fit in the forks. unsure what'd that do to the fender/speedo though.
quick math shows it'd be about 1.29" shorter, and about 8-9% hit on speedo. so it'd actually be closer than a 110/80 radial on a stock rim then.
