TOPIC:

Hi there,
Just to start of I'm a complete novice at this so forgive me If I sound thick.
(I bought this bike as you see it, the only thing I've done is change the handlebars and put a new exhaust on it)
I'm starting a project and I would like to get some feedback on what kind of swingarm I could use on my KZ650B frame.
I already have a GSXR SRAD 750 front end with wheel and I would like to get a matching rear wheel so wondering if it would be ideal to swap the swingarm for something more modern. Then the plan is to tidy up the rear end perhaps put a tail on it.
Are there any charts that you can tell me which swingarms fit my bike?
Any help would be truly grateful.

Bike is registered as a 78 Z750, it has had a 84 750 lump put in it (info came from Kawasaki).

Here you will find a great Chart for your swing arm wheel opening/axle/pivot/frame width , forks, brake disks, rear suspension dimensions.

Fantastic!!
Thanks very much.

Does this chart tell me what fits or is this just telling me what the dimensions are of my bike?

This is the part number
33001-089 SWING ARM 1 KZ650-B1

Theres plenty on ebay, search z650 swing arm. Normally some custom stuff also. Dresda, Davida and Metachex all made custom swingarms for 650's.

your bike isn't on that list. You need to measure what you have and compare it to see what might fit. Most of those swing arms on that list are for mono shock bikes. They will require a significant amount of fabrication to fit. I would suggest looking at a swingarm from a twin shock bike such as a GS1100E or a ZRX 1200. I doubt either will simply bolt in but I think something like that would be the easiest route, other members here have made them work.

The biggest issues you will have running a big rear wheel is chain clearance to the frame. you will need offset front sprocket, you may need to cut and channel the frame, and/or turn down the sprocket carrier and probably make custom wheel spacers depending on whats going on. There are many factors to consider.

Here's a customers bike, that's the shortest arm I could build to fit a 5.5 wheel/180 tire combo and clear the rear footpeg hangers.

thanks for the info but unfortunately he is a bit far away from me.
I'm in the UK.

I suppose I should check that the Suzuki GSXR rear wheel can fit my current stock swingarm before i go down the route of a new one.

Are all GSXR rear wheels the same width?

I am pretty sure that the 600/750 has a 5.5 inch wide wheel, while the 1000/1100 has a 6 inch wheel.

You should have plenty of resources over in the UK.
Find a custom, fab, cool (TV show style) shop to help you out.
Dime City, Legends, Ace. Even ask The Harley Guys! Business is money.

Go with the GS 1100, Or GSXR your cheapest alternatives. I have a picture with dimensions in inches of a GS 1100 Suzuki swinger here.
Give you the basic idea size.
