So I have a 93 VFR swingarm coming my way and I have questions about mounting a 3 spoke Ducati rim to it. Ill start off with the facts I know of first:
1. I need a triumph eccentric hub.
2. I need some kind of sleeve made to fit the wheel snug onto the hub.
3. Its expensive.
That being said heres a few questions I have yet to get answered...such as:
1. What are the dimensions of the sleeve I need made?
2. Can I run a 6" Ducati rim or just a 5.5"?
3. Is there anything else Im missing?
Id really appreciate any insight on this, and on that note I give the floor to the gurus.

May I ask why you decided on a Ducati rim? I am looking to do a similar swap but I will be using a Triumph (955i, ST) rim.
I have not attempted this project yet but I would be interested in knowing more.
Talk to Kurt, member name "Taglicious". I believe he has done the Triumph ST eccentric swap.
if your using a duc 3 spoke.. you just need to have the axle cut and treaded.. look it up.. somebody did a post on it..
First off, you need to fit the swingarm to your bike. Only then can you start figuring out the size of the spacer you need to fit either one of the wheels. Please understand that any info you pick up here about spacer sizes has a risk of not working AT ALL in your SV! This is because the swingarm will likely not be installed on the same center line as on the VFR(correct me if I'm wrong here); this means that the wheel mounting surface AND the sprocket will be off and possibly require 2-3 spacers(as I told you on CF). IIRC, the 90-93 swingarm has enough clearance for a 6" rim when installed on a VFR, so that should work in your SV too. (the 94-97 VFR will NOT accept a 6" wheel installed as standard in a 94-97 VFR)
If you know more about the SV swap than we do, post it up so we can help you better!
Yeah, really depends on what spacing you have from the VFR swingarm to the SV. If you get it to the stock VFR position (relative to the bike's centerline) then I found you need a 5mm spacer for the wheel.
List of parts I used:
Triumph cush/sprocket carrier (I think the VFR one would work as well)
2.5mm spacer (for chain alignment - may not apply to you)
Triumph eccentric
Triumph axle (rethreaded down to the shoulder and excess cut off - very hard metal, heard some machinists don't want to do it)
5mm spacer (for wheel alignment, best I could figure)
Triumph rear brake caliper and caliper bracket (rear brake is 2 piston design, similar to VFR)
5 spoke Monster wheel
I've been real happy with mine, only problem is that with the 7.5mm of spacers it leaves the sprocket carrier side of the axle shorter so the lock washer will barely lock with the crush flange. I've put 10k miles on it without any issues but it's something to be aware of when you figure up all of the spacing.

I think a 5.5 is the widest that will fit with the 94-97, not sure about the 90-93 models, but I have a feeling that it will be very close with a 6"

Matt, did you look into removing some material from the sprocket carrier to allow the nut to thread on more?

No I didn't, that would probably be good and get you a few mm back, I wouldn't need much to get it back to flush with the flange on the nut. I'd really like to put a cotter pin in that nut just like on the wheel side, there actually may be room for it...
One thing I've really wanted to try is an NC30/35 sprocket carrier with the Triumph axle, it may not be as wide and is certainly not as heavy without the cush

I actually bought this swinger off taglicious lol! IT was my understanding that I needed a sleeve to go around the hub to be big enough to fit snug in the hole for the center of the Duc rim.

Ducati eccentric is smaller than VFR's, henceforth if you want to use it you need that cylindrical spacer. Other than that the Ducati and Honda parts have similar dimensions, although the mounting setup for the brake stays are quite different. There was one member on vfrD who said he had made it work, but could never provide finished pictures and at one point asked me if I wanted to buy it.
Then he vanished, so I would have to say :worthlesswithoutpics:

Ah finally I get it, the spacer is to mount the triumph hub to the VFR swinger, not to mount the wheel to the hub! Is this a part I can buy, or will it have to be machined?

Nope, the Triumph eccentric slides right into the 3rd/4th gen arm. The Triumph and Duc parts are both smaller than the VFR800 part, and the Duc is smallest of the 3. To put the Triumph eccentric in your arm, you'll need spacer rings to go between the cush drive and eccentric to line up the chain(possibly), and a spacer ring to move the axle to line up the wheel and clear the brake caliper(possibly).

Do you know if these spacers are something I can buy at a hardware store are they something that would have to be machined? Uhh wait, you said VFR800? did you mean VFR 750? I have a 93 VFR 750 swingarm.

Better? The rings would need to be machined.

johnny... you make me giggle
duc and tri spindle(s) are smaller than the vfr 750 **only on the wheel side of the eccentrics by 5mm diameter... **
you'll need the smaller eccentrics
with the dish of the duc being different (only because of the width of the center portion of the hub, which makes the offest a wee bit different), you will need a 'sleeve' as you so call it...
I sent you the micro fiche on CF for duc with a PDF (lmfao sounds like code)
Also, if you guys plan on doing the change like I did with the triumph, look at that thread.
I forgot to put that in there - for the eccentrics & spindle (triumph) going with the wheel...
I also hacked, threaded, and drilled pin holes about 1" in on the (wheel side of the spindle)
and on the drive side I used a shim half the thickness. betwixt the cush and eccentric bearing...
whew...
you should've let me know what you were doing before you bought it cracka...
if anything you're gonna be an aficionado
