So I just got my vf500f and got it running and need to make it streetable. I was trying to find rotors cause mine are pretty bad. I cant find any stock ones that look good and im not buying the ebc. So this rear rotor from a cb1300 Here accorinding to what ive read has the same measurments as the front of a vf500f. So coudlnt i use this or is my logic flawed??
