FZR1000 rear wheel - my google-fu is failing

So, I thought it might be kinda cool to put in an FZR 1000 rear on my 93 ABS.

I am failing in my search on this for some reason, as a lot of what I'm finding has to do with the 18" FZR wheel, and I'm looking at the 17"  one.

1. The correct wheel is from an FZR1000 and is marked at 17x5.50
2. This is going to let me keep ABS operational, right?
3. Some small amount of machining is required, right? IIRC, a few millimeters need to come off the sprocket carrier. I know those English blokes have a kit, but with shipping it sounds kinda spendy.

Unless someone else has found a compatible wheel in use and chimes in. I Do Not believe that there is a 17" rear wheel that is an easily modified example. I also believe that the 18" FZR1000 kit from the UK FJClub does not offer the ability to retain the ABS feature. I also believe that the 18" wheel is only 4.5" wide.

There is a member here that has an XJR1300 wheel that has been modified to accept the FJ ABS hub. All of the work was done in Germany and then shipped to the US when finished. Jon Fife has stated that the individual that performed the mod, no longer does them.

The UK kit specifically says it fits the 17" FZR wheel, not the 18". The 18" wheel is supposed to fit without it.

18" wheel is 4.5 wide. The 17" is 5.5.

To minimize machining you can also use an offset countershaft sprocket.  You MAY (or may not!) have a small intereference issue with the frame inboard of the foot peg mounts - depending I think in how neatly that area was welded.  It doesn't take much work with a file or grinder to clearance it.  It is the same area you have to deal with when using an XJR engine (or an XJR output shaft) in an FJ frame.

The YZF1000R "thunderace" had 17" hoops.  And with a 180 rear I would bet it sits on a 5.5" wide rim

Did some more googling.

Looks like I was mistaken about keeping the ABS. Unless there is a bunch of milling done.

The FZR wheel has a bunch of webs where the cavity for the sensor is. If the hub is the same size it shouldn't be that big of a deal to mill it to take the ring gear. What it lacks is the bosses for the screws holding the sensor in. Also not sure if the brake rotors bolt up.

Thunderace wheels are harder to come by than FZR. Also, the casting looks like there is no way to mill it for the sensor.

I saw that Randy has a 17" 5.5" wide ABS rim on one of the FJ's in his shop, so we know that they are out there..........somewhere they exist.

The problem is, we don't know what bike the ABS rim came off of......

Perhaps he has an update.

The FJ ABS wheel can be modified and turned into a 5.5" wide wheel. But the cost must be prohibitive.
The glass is not half full, it was engineered with a 2X safety factor.

Yes, at $755 per wheel is stupid expensive.

Here is what the rims look like from the right side.

It should be pretty obvious what I'm talking about with the webs and the cavity.

It would be super cool to make some measurements, but I'd have to lay out the money for the rim to do that, I suppose. I don't know how important the bosses for the ABS tooth ring are. The ring doesn't really have any stress on it, the screws are there just to keep it in place.

You're right, my bad.

How about the Yamaha GTS1000?  That had ABS and a fat 180 rear tire.

That looks like it's got the right sort of cavity. I'm sure the ABS interchanges perfectly.  But holy heck is this an even more rare wheel than the Thunderace...  :wacko2:

Hah!

I ran an interchange search for the tooth ring.

The only two bikes to use this ABS system are FJ and GTS.

Ain't we special...

I found the thread with the XJR wheel machined.

http://www.fjowners.com/index.php?topic=13698.0

It actually looks exactly like the FZR wheel. And the machining looks exactly like what I said - milled out webs.

I might actually toss a couple of bucks at this and talk to a machinist friend.

Maybe John can share the contact info of the guy in Germany. Then he might share some sketches or drawings of what needs to be machined. I see that he has not logged in about a year now but it might be worth a shot.
