I have read all I can find on the FZR front wheel installation and I wonder if you all could clarify that ONLY the 87-88 wheel will bolt up without modification? There seems to be far more 90s wheels out there for sale and I wanted to see if anyone knew if these would work as well? Thanks in advance.
Depends if you want 3.5" or 3" ,, no mods with the fzr wheels you asked about, but if your changing up from 16" rim 88 and up fj,s have 3" rims,

Yes, I can confirm that, only 87/88 will bolt straight on. The reason for theres allot more 90+ rims, I don't really know. But the 87/88 is in high demand amongst FJ owners, and probably among other bikes too.
90+ FZR rims uses 17mm bearings and you would need a bigger axle then the FJ axle to fit it. But then it won't fit the FJ forks etc. etc. etc....
87/88 rim is a direct bolt on, all the axle, spacers, speedo drive rotors fit.
A while ago i another thread (when I did my FZR mod) i bought a 90 rime (the wrong one obviously :dash2: ) Pat then had the current question for me:
QuoteKen, just curious, what's your plan on adapting the 17mm bearings used in the FZR rim, to your 15mm axle?
Then got a 87/88 rim and and bolted it straight on :good2:
I used an fz1 rim, and had bushings made so I could use the fj axle with the 21mm bearings
i got an exup wheel by mistake from ebay (was not sure from description but was very cheap, £15 and freshly powder coated black so took a chance) and as no bearing seem to exist in the right size my local bearing shop had a 1mm shim which fits inside bearing to make perfect fit and seems to work very well, has done 5000 miles on it with no problems

I converted last winter with no problem using an 88 wheel.
For future help to others who want to use an exup wheel can you post the manufacture, part number, and cost of the 1mm spacer ? They are difficult if not imposable to find over here. It might help other members out as 87 - 88 wheels are in short supply. :good2: :good2:.

Well It sounds like all I need to do is get a bushing to adapt the larger ID of the bearings in the post 88 rim to the smaller FJ axle right? that shouldn't be too hard. That would be real easy for any machine shop to do cheap I would think. Too bad I don't have access to a lathe anymore :(
I'm using a 17 x 3.5 inch XJR1200 front wheel with the FJ 3CV forks drilled to take the 19mm XJR axle, and then a lock nut to secure the axle.
There ya go, just bore out the down tubes to the correct diameter and use a lock nut instead of the threads in the down tube. good Ideas here thanks.
As I've said before, personally, I would be concerned with a 1mm thick bushing on my front axle..
..but that's just me...it's only the front wheel after all...what could go wrong?
Is there a bush there to start off with? One leg clamps up on the axle and the othe has a thread to take the axle thread.
All that i've done is to bore out the lower legs and remove the thread. The axle doesn't turn does it? Are the fork lowers toughened in any way?
I personally can't see a problem and neither can my engineering friends.
No, that's not what I'm talking about...
I'm referring to using the oem FJ front axle (15mm dia.) with 1mm bushings so that the 17mm id bearings in the '89+ FZR wheel, works on the oem FJ axle.
The load path transfers directly thru these 1mm thick bushings.
Ah, the wonders of internet forums.
Sometimes things just happen to translate in the wrong way.
Must gen up on the FZR front axle :scratch_one-s_head:
There wouldn't be any problem with the load path through a properly fitted bushing, that's a completely uniform radial load around the shaft of the axle and the ID of the bearing, essentially straight compression load through the thickness of the bushing material.
I also like the idea of just boring out the leg and putting a nut on the end, very simple. Now if I can just find a post 89 fork assembly, they're getting hard to find.

For those that weren't here last time this topic was up:

The right 87-88 rim will turn up sooner or later. I would wait it out.
My 2¢.

unfortunatly they have no labels or manufactures marks, they were just something local bearing shop had in, they were about £5 for four if i remember rightly and i bought all they had at the time (4) i have not been back since i got them (last august) but will pop in next time i am passing to see if they have any more in.

I put a 92 0n
