FZRSupport: the FZROnline Archive

I have looked and looked but can't find a how to, to make this fit. I've contacted speedwerks and the kit they sell is $300 including a brembo caliper. I was just wondering if anyone here could point me in the right direction or a link of how I can make this work myself without spending the money to a company for a kit. I would like to do it myself.

Im assuming you already have the wheel, and that's why you don't want to use a YZF swinger/wheel assembly?

Yea. I got the wheel. The axle fits and it fits in the swing arm. I got the wheel and tire with rotor and hub just wondering what I need to make it work.

Either some sort of spacers and/or offset sprocket I assume. Everyone uses zx6r front sprocket since it's offset a bit, and also swap to a 520 chain as well since it's all apart.

I need sprockets and a chain so trying to figure out the swap before I buy them.

Well you could do it the old fashion way if you want to do it yourself and put the wheel in the swingarm and line up the middle line. Then start measuring what you need to space the sprocket out to line the chain up straight. From there you'll need a bracket for the caliper side. If this seems too complicated then pay speedwerks.

false. I pointed him in the direction to do it. I have no idea of his skill level for modding. So if what I described seems too complicated then speedwerks it is since they offer the kit. If the axle is the same diameter then it isn't going to be hard to center the wheel on it and start taking measurements.

I've done wheel conversions before and I think what you will learn by doing it yourself is that you will wish you had bought somebody else's kit for $300. Unless you really enjoy the experience and frustrations at DIY on something like this.

This is not something you can do with a bunch of flat washers. If you want to do it right you will have to have machine work done. If you own a machince shop or you know somebody that will do this for you for the price of materials and a small fee, and can do it in a reasonable amount of time, then you are off to a good start in doing it yourself. If you don't have any of this then machine time alone is going to cost you $150 to $300. It will be challenging to find a machine shop that will do a job this small.

The other thing you will have to do is take precise measurements. Even with the right equipment, which if you don't have obviously adds to the cost, you may be a little off so there will be a little trial and error.

It's not just about fitting the wheel in the swing arm, you have to make sure it is in proper alignment with the front wheel. You may need to redo all of your work on you custom spacers in order to achieve this.

I say go for it if because as with anything, there's a certain level of satisfaction gained when the job is done.

So here is the response email I got back from speedwerks:
you need an sv wheel 99-02 complete.
we need the SV sprocket carrier sent in for a core exchange.
everything is bolt up and go,you can switch back to 18 anytime.
you will need appropriate gearing 520/525 thanks

They want the sprocket carrier because it needs to be machined to line up the sprocket with the front sprocket of the FZR.

The price certainly is kinda high, especially if you didn't already have the wheel. It all boils down to how badly you want to do this yourself, and how badly you want to do it at all.

Took a few rough measurements and the fzr and sv wheels are from inside the rotor to outside the sprocket are both the same at 7 and 1/8 inch. The rotors are a little different in size. Sv is 240 and the fzr is 245. I'm thinking the caliper will still work. And whoever really uses the back brake anyways, I hardly ever do. Lol!

I had put the sv wheel on and fit fine. It rubbed on the brake arm so ill be making a new one of those. The chain wouldn't fit because of a 47 tooth sprocket. I'll try to throw the sv wheel on this weekend when I'm off and take some pics and a few measurements.

I already have the rear wheel with sprocket carrier, rotor, almost brand new pilot power 160/60 tire. Even have the front with tire but no rotors.

Any chance that you can take some photos for a comparison? Im curious to see the two side by side

id love to buy a single swing arm conversion kit ready to go ..

I'll try to mount it up tomorrow and take some pics.
