Metmachex and JMC make some beautiful arms. What are you after? perhaps a double clubfoot?

I believe JMC is no longer in business, but you may find a used swing arm they made. Ed

im really not to sure what im wanting yet im getting the bike with in the month, have yet to get messurement and such im looking for something that i can pretty much bolt up with minamul fabracating

You should ride the bike with the stock swing arm for a while before deciding on a swap. You will find as long as you have decent shocks the swingarm will handle anything you can throw at it without a problem. The KZ650 swingarm was a better match for the bike's weight and power than some of the swingarms on the larger bikes. Notice in the video below, where the KZ650 at Daytona averaged 117+ mph over a 24 hour period, the stock swingarm was used, but they put on better than stock shocks. I doubt that we mere mortals will place greater demands on the swingarm than those of the Daytona speed records, so if you decide to switch the arm it would be for aesthetic rather than performance reasons.

Me neither. Ed

There like that so when your opening the big 1400cc motor, its like your ice skating. lol But seriously i see what i my 1327 will do a 190/19 hayabusa rear tire and rim. It will just smoke it off like its a 120. If i am getting on it decently hard shifting thru the gears it acts like it was to get away from you, it will go sideways if you let it. I couldnt imagine being on those tires, you wouldnt even be able to take off fast, or get into.
