what year and model vmax? spindles are all the same, save viper and some xtc's. difference from an "r " stamp to a "v "stamp is in the angle of the caster. an "r" ta will interchange with a "v" ta as long as you take the time to align the front end and reset caster and camber, and perhaps a shock adjustment, and change ta's in pairs. dont have a" r "on 1 side and a "v "on the other. there is only a 2 degree angle deviation between the "r" and "v", otherwise the same head design for spindles. this is verified info straight from yamaha printings, as well as personal experience.
