Suspension/Fork mods for 1978 KZ1000 frame

I am new to this site and this is my 1st post. I have a 77KZ1000 ltd rigid custom that I plan on putting back into a 78 frame. My back just can't take it anymore and I want to be able to leave my kidney belt at home when I travel more that 50 miles. I have an old SBF rigid frame, HD 35mm front end and run a 150/80 16 rear wheel/tire. I would like to know what are the most current fork,swingarm mods that I can use on the 78 frame to make it handle better and still be able to use the rear tire set up. Thanks for your time!

The easiest road to what you want would be a stock frame, stock front suspension and a GS swingarm.

I got an 82 zuk gs 1100 swingarm on mine and the 150 tire will just fit, I found mine on GSresource parts thread for a 100 bucks, thats a badass bike too bad

I have the gs1100 swingarm on my 78 frame, worked great a little tweaking nothing major,just make sure tire is centered.

yea I think I had to add a couple of washers, that was it

Even if you simply use the stock frame/swingarm/fork you will find it handles better than your current configuration. Hardtails are not known for good handling characteristics. Ed

Keep in mind that he is using a 16 inch rim.

You may be able to fit a wider tire in a stock swing arm, with the smaller rim.

If you measure from the center of the wheel to the widest part of the tire, I have a stock swingarm I can measure at that point.

cool bike,i thought it was a flat tracker at first! :laugh:

If you still want to keep the style your bike is now you can use a plunger frame. Not a full rear suspension but not a hardtail either.

Tell me about it. I have to turn corners like a car but when I straighten out, she runs like a bat out of hell:woohoo: !! My riding buddies think I am crazy to ride this on the interstate.

Yeah ,she was a digger when I first put it together

Thanks man! I did the white walls by hand, ol' school!
