TOPIC:

I have a 1977 KZ 650 I want to mount a new or used swingarm on it that will hold a 160 or 180 tire. I also want to have a little extension to it, 22 to 25 inches long from pivot to ecentric. Disc brakes with master are needed to. Any Ideas to what will fit that I can purchace. I have about $230 to spend.
The pivot point on the frame is around 9 1/8 inches. If i need to go to a mono shock that is no problem. I'm also looking for the rear adjustment to be the rotator type like the gpz.

Early GSXR swingarms might work. Typically get 3" over on length. Popular mod for KZ in my town. Twin shock mounts can be welded on. A 750 triple swingarm might be a cheaper option. Not sure if you could get a 180 tire in it though. Maybe a 160.

I have a suz gsx 1100 swingarm on my 650, wasnt a great deal of hassle to fit it, I have a150 on it at hte moment but a 160 will fit no worries but I dont think that you will go much bigger than that. I have used the stock 650 axle and changed the bearing size to fit, also had to machine up a few spacers as the 1100 swingarm is shorter than the 650 one is between the frame, I ll take a few pics of the arm if you wanr.

Cheers

Remeber that a wider tire usually needs a wider rim. That will inlolve getting a extender front sprocket so that your chain will still be alligned.

Thanks for the replies guys. I didnt think about the chain might need to be moved. If you guys have pics please send them. I need I ideas, and most important a swingarm setup.

If you want to run a 160 tire you could pick up a zx6 4.5" rim which will hold a 160 tire. As far as the swingarm goes a suzuki gs1000sz (katana)from 82-83 or a regular gs1000 has an aluminum swingarm which will bolt right in with only two washers on each side to take up the space. This is what i am running on my bike. The only thing you will need to change is the rear wheel bearings and the rear caliper bracket. The small kz (650/750) have a 17mm rear axle where the larger brothers have a 20mm. The suzuki also has a 20mm axle. If you go into the archives i did a write of with pics of everthing you will need for this conversion.

I still have a swingarm and brake set up from a 83 gpz750. Let me know if you want me to measure it.

galaxian: it appears the links to your pix in archives are broken -- care to repost more shots of your too cool setup?

I have a GSXR Mono Shock setup. The pivot point is
9 7/8 in. and approx 23 in. from pivot to axle. I have the shock,mounts,and the rear brake caliper and master cylinder.
If you want pictures i'll have to email them as i am not able to upload pictures from my computer.
I'm leaving for the Boston area and will be home this weekend. Roy
