ZX7 wheel swap onto a 1974 Z1

Hi guys, Have any of yall ever swapped a rear wheel off of a 2000 zx7 onto a 1974 z1? I have a complete 2000 zx7 with the front end wiped out but from the header back is complete and I would like to put the rear wheel onto my bike. also would one of you guys please post the demensions of the swing arm that I will need please. A pic. with measurements would be nice as I have a friend that works at a machine shop that will build me one if I can get a diagram. Sorry for all the rambling and Thanks in advance;)

You can do it. The problem may occurr with your passenger peg brackets. Your swingarm is likely too big to keep those braekts there; just whack 'em off (sawz-all) and relocate your passenger pegs via a set of late-model passenger pegs and brackets. Also, the ZX7 arms in particular flare out from the axle-bolt very dramatically...enough so that the swing arm may foul the frame, the only way you will be able to figure that out will be to pull your rear end and put the ZX arm in and see if it will go.
Next issue: single shock or keeping the twins? Keep the twins and you need to mount brackets on the swing arm for the shock mounts. If you go single-shock you'll need to measure and fashion a top mounting bracket for the top of the single shock...likely in the area of your battery box.
Next issue: if you're going to keep the wide wheel you'll need to have an off-set front sprocket and if it's a 5.5" wheel (or wider) the off-set will likely have to be off-set enough to require an out-board bearing support plate that will support the off-side of the sprocket. If you go with a 5" wheel you can get away with an off-set sprocket only. This will also be an issue that will allow (neccessitate) you convert to 530 or a 520 chain/sprocket set-up.
Next issue: use the ZX rear-sets so that you have minimal fuss with the routing of your new rear-disc brake set up. Either bolt a rectangular plate to your frame in the "foot peg" area and then drill-and-tap the plate for your new rear-sets.

Lots to do; but it all lines up, and many here have done the exact thing you are attempting. Good luck. "Axe" questions. Welcome!

i dont know about zx-7 wheels but i'm about to try a crazy swap my self i got a solid disc wheel from a v-rod 18-5.5" that i'm about to atempt to install into a gs1100 swingarm this could be fun i need a rotor and i have to find an outfit that can cut me a rear sprocket this could be fun.

no its been proven in repeated lab testing that sportbike wheels wont work on a 73-75 z1,neither do usd sportbike frontends .something about the welding on the kickstand bracket not being compatable with newer radial tires,i know who wouldve thunk it but im just looking out for ya here.although ive heard rumors that the kickstand mounting bracket welds on any of the kz series bikes 76- are suitable for chopping up any way you like. :woohoo:

:pinch:

So true, I went through many saw-zaw blades on hacking my 1976 KZ900..... :blush: :blink: :huh: :dry: :laugh:

Thanks for the info guys, I just got my stock swing arm finished I cut it and added 4 in. to each side I had to make a new axle also as it got wider with the extension and I will have to do some more machining to the axle so that my stock chain adjusters will fit. Now the tire and rim fit very well. Also I didn't have to cut my kick stand as my bike is a 1974 z1 not a 1976:laugh: I will get a few pics posted soon.

Damn...I wonder what that 'arm' weighs now.

Don't know yet, But as soon as I get the cherry picker out so I can get it on the scale I will let you know..lol

z1 frames require a lot of bracing in with mild engine work they are over stressed in stock form.adding stiff suspension and sticky tires really adds to the frame issues.

Well I got the arm done. I built a axle for the drum brake wheel 16 in. oldschool harley rim laced to the drum brake hub weighs 49 lbs.complete the zx7 wheel complete wiighs 40lbs.- the stock arm weighs 9 lbs 9oz. the 4in over arm weighs 13lbs 6oz. So the weight savings on the zx7 wheel will more than makeup for the added arm weight I still have to make some bushings so I can use the stock diameter axle it's 20.20 mm and the zx7 axle is 25 mm so for now I'm gonna use the 16in wheel. Gotta get back to work on my motor my cylinder head will be back Monday ported with a valve job. Any way I hope these pics work.

how about just swapping the wheel bearings to match stock axle to newer wheel?
