The 16 inch front wheel of my old rg250 (not rgv) worked very well indeed, as did the anti dive it had that's another thing that has gone out of fashion now. In fact my enduring memories of that bike are mainly of how excelent the whole front end felt. I'd go as far as saying it was better at very late braking and quick turn in without getting upset than my rgv or my aprilia rs's (probably partly due to it being lighter than either as much as the 16 inch front wheel).If the nsr's steering geometry is conservative enough then it might be worth considering.
