Hi guys.
It's hard to find a '87-88 FZR1000 rim but I found a nice JF1200 one. Anyway...besides FZR1000 rims being 3.5" wide and the FJ1200 '89 rims being 3.0" wide, what's the difference really?

The 1/2" wider wheel allows the front tire (120/70-17) a slightly better profile.
It's not as pinched on the wider rim, and gives you slightly better contact-patch.
You will be able to use more of the available tread of the tire.
Most normal riders would never be able to notice the difference. Those that push the limits, will notice a slightly more planted front end. :good:
Get the 3" FJ rim now and run it while you wait to find the correct FZR rim - just my two cents worth

Actually I just found a correct FZR rim, just after I posted my question. But it's in pretty bad shape and I need to have it sandblasted and powder coated. The rim would cost 3 times more than the FJ1200 rim I also found - which looks like new.
This article http://www.fj1200.info/Rims.htm (http://www.fj1200.info/Rims.htm) is suggesting that a 110/70/17 front tyre and a FJ1200 rim would make a nice combo.
But the guy who wrote it also says there is a huge difference between the rims.
Is the difference between them really as big as he states ? If so then I would go for the FZR rim.
Steve (Morarman) runs a stock front wheel with a 110 wide tire. He is quick in the corners, no problems with sport riding. Unless you are ride out to the edge of your tires the 3" wheel will get the job done and as already suggested, you can keep shopping for a good condition FZR wheel. A session with paint stripper will save the cost of media blasting. Paint with a rattle can and then clear coat it if the budget requires it.
I went to ebay when I was looking for a 3.5 front rim, punched in fzr750 and one popped up for 60 bucks and make an offer. I offered 30 bucks and he took it.
They're out there, sometimes you're just in the right place at the right time. It's kind of a matter of how much patience you have to wait for what you want.
My bike is an 89, so it already has the 17X3.0 front rim.
I'm going to the 3.5 so I can go to radials.
Every bike I've converted to radials has handled better than the old bias plies. Better selection too since the 3.5 can accept a modern 120 radial.
That being said, my OEM 3.0 rim handles just fine. It has a bit of a tendency to "fall in" when cornering. But in all fairness, it's also the tire that came with the bike and it's old and worn. The flat center rear tire probably doesn't help that fall in tendency either.
FYI, you can run radials on the stock FJ 17x3 front wheel. It rounds the tire over a bit more than you'd get on a 3-1/2" wide wheel, and you'll never get the bike leaned over far enough to use the outermost part of the front tire tread. But I have done probably 100,000 miles on 120/70-17 front radials and every foot of it has been better than bias plies.
One of the biggest improvements I'm hoping for in a wheel swap would be weight. YIKES the factory wheels seem heavy.
A 110/17 radial works well on a 3" rim. I am using much more of the outer tread than when I had a 120 mounted and it turns in better
Just get the plentiful '90+ FZR wheel and drill your forks out to 17mm. You'll need the speedo gear and axle as well.
Check this thread: http://www.fjowners.com/index.php?topic=13479.15 (http://www.fjowners.com/index.php?topic=13479.15)
I did on my set few kilometres and I love it. Especially with passenger.
You will not notice it straight after swap. But after few km and few bends, You will know that was good decision.....
So I just called a buddy of mine who told me he can drill 17mm wholes in my forks.
But does that mean I can use any other rims from any modern bike as long as the break disks are of the same size as on '89 FZR or JF1200 ?
BTW, I already bought YAMAHA R6`01 calipers. Will they work with the '89 FZR rim?

Does the FJ cable fit the speedo gear and the OEM FJ speedometer can be retained?

Oh, so you just replaced the bearings in the rim. How clever!

They will work after you swap out the 320 mm discs for 298mm FJ 1200 discs. The threads are the same on all the Yamaha speedo drives.

I think so, as long as the speedo gear fits.

Isn't 282mm standard for FJ1110? Or do you mean you need 320mm disks with FZR1000 87 or 88 front rim?

Once you put the forks, calipers and rotors on that part of the bike is no longer an FJ1100. The forks determine where the calipers sit, you will need the 282mm rotors.

So what you're trying to say is I will need 320mm disks with FZR1000 rim?
I reread your answers. I already have 282mm rotors on my FJ1000. No idea why you mentioned 320 mm discs (I never mentioned them).
Guess I can keep and reuse them with either 87-88 or '89 FZR rims.

Ezunix,
You have an FJ1100 correct?
To accomplish the front wheel swap, you first have to fit the front fork lower legs from a 1989-up FJ1200. This is the first, and most important step. You cannot use the 1984-1988 forks without having to find or fabricate some sort of front caliper adaptor brackets.
For the front wheel, you either need to source a FZR1000 wheel from 1987-1988 only(17 x 3.5"), or a 1989-up FJ1200 front wheel(17 x 3"). These are a direct bolt-on to the '89-up forks with the 15mm axle.
Use the FJ wheel spacers and speedo drive. Make sure you have the tab-washer that actually turns the speedo drive. Use the wheel bearings that came with the wheel, or buy new FJ bearings.
(you can use a 1989-up FZR1000 wheel, but you will need to drill the fork legs for the 17mm axle, and use the speedo-drive from the FZR1000. I am not sure if you can drill out the FJ speedo drive? I've never heard of anyone trying it? You would also need to source an FZR1000 axle and spacers. Some years of FZR750 may be similar?)
The brake rotors you have to use are the '89-up FJ1200 brake rotors. They are 298mm diameter. These are the only brake rotors that will directly bolt to the FZR1000 wheel, and be the correct diameter for the caliper placement.
You CANNOT use the earlier 282mm rotors, or the FZR 320mm rotors.
The R-1 mono-block calipers are a direct bolt-on to the '89-up FJ1200 fork legs, in either blue-pot, gold-pot, or silver-pot style. Some R-6, FZ-6, FZ-1, FJR1300 front calipers are the same.
DO NOT use any used brake pads that may come with the calipers. Either buy new OEM Yamaha pads for the R-1, or get some EBC FA252HH front pads.
With all that being said, this is the easiest path to the front wheel swap.
However, anything can be made to fit anything else with the use of custom machined spacers, adaptors, and different axle?
There are some that used custom sourced bearings to adapt the '89-up FZR1000 wheel to the 15mm axle size I think?
I'm not sure what your budget is, or if you have access to custom made parts?

Sorry about confusing the discussion, its just something I'm really good at :crazy:
I mentioned the 320mm rotors because that was what came on the FZR 1000 wheel that I bought. Anyway, Alan has outlined the whole process perfectly. These are the parts you need to make it a bolt on project. I think it's well worth it.

I bought R6 callipers and they came with decent break pads. Why can't I reuse them..?
And thanks a lot for your answer!

The brake pads
may be good and
may work well. The critical word here is "may". They are your brakes, they may or may not perform as you expect. For example, they might have been exposed/contaminated by fork oil due to a bad seal. The bottom line is it is your ass (and any passenger you have along) on the bike. He wants you make the safer choice over some cost savings.

Agreed. Take Mark's advice. As a friend once told me " John, I can't afford to save money".
Scrub the old transfer layer off your rotors and start with a fresh set of pads.
The reason: You don't know what pad compound the PO used on the rotors and chances are you do not know what pad compound those used pads are... Some pad compounds are incompatible with each other. When changing pads to a different pad compound it's not as simple as just changing the pads. You have to take into account the layer of old pad compound on your rotors (aka transfer layer) and scrub that off as well.
Who knows what you have?
Start fresh.

Just to add a bit balance to the advice already given here, yes you can but they will likely feel like wooden blocks compared to the EBC HH pads that many of us use.
Sure, the procedure Pat described is best practice, and I recommend it, but don't have the fear of God put in you if you don't.
The face of the pads will be grooved to the profile of the last discs they were matched to and will not have full contact, it will take a few hard applications to match them to your current discs before they become fully effective.
The transfer layer happens, but in my experience, doesn't relate to much on the road, although scouring them is a good habit it's not crucial.
My brakes and tyres work very hard and are the most important thing on the bike and I wouldn't take a chance with either but I've used second hand pads many times. Although not my first choice, I have no problem doing so, nor sending customers bikes out the door with them once satisfactorily road tested and bedded in.
