rear hub is 36 spoke and front hub is stock with machined spacers to except 1991 fzr 600 rotors.hopefully soon I will have wave rotors. yes ,twinsarehot you are correct I had omars terrazi rear sets on it till the end of last summer.their nice and look good but the stock pegs more cozy.I started as a cafe racer and ended up going to tracker. all my cafe parts are slowly landing on my extra bike. I have a nice cafe 1978 xs 650 in a corner of my garage now collecting dust.guess I,ll get time for it some day. twinsarehot I must hear that pipe on your bike,hope to see it out this summer. what look are you going towards with your bike. cafe,tracker,brat,bobber.ect. you now what I mean.all I can say is stick to your plan because changing your mind 75% of the way through is expensive.but where never done and thats the fun of it.
