SAFE-T

Get Tony Foale's suspension analysis program (BLS has one...) and plug in your numbers, then. You will probably have to raise the rear ride height a bit to adjust for the increased trail. You will end up with slightly steeper rake than stock. cassandtim made his own triples.

The dreaded Paralysis of Analysis. Just get a CBR929/954 or RC51 SP-1 lower and a CBR929/954 upper and forget about it.

$350 plus 5% GST, plus shipping back and forth. You need to supply a set of RC54 drive pins and bolts as these need to be press-fit, along with an OEM 46mm Ducati three-peice wheel nut because I want to make sure everything fits. Once you get it back, you will need to fabricate your own rear brake caliper stay using a brake caliper of your choosing, since we are still working on that. If I were you I would wait, unless you want to do your own experimentation. The VFR800's stock rear brake caliper and stay will not work. I have one other member on the board who is interested and who I have agreed to do a spindle conversion for at cost ($350 plus 5% GST), for which I hope to gain some information myself. If it were a bolt-on conversion right now - including a substitute rear brake caliper and stay, RC45 drive pins and Ducati wheel nut - you would be looking at around $1000.

I can make any number of them as long as people pay for them :fing02:

Interesting that the bearing journals still match up, but I've heard the same thing about the VFR spindle in the Hawk eccentric and vice versa. What are you going to use for a rear caliper / brake stay ?

I'd scour the HawkGT forums - I bet they are pretty close, though. But you can't use a Duc wheel on the Hawk spindle without relocating the drive pins. You might be able to use an NC35 rear wheel, but again I think the drive pin circle is different.

Be interested in knowing which of these wheels, if any, actually clear the 3-piston rear caliper on the VFR800. The smaller RC30 eccentric will need a cylindrical spacer in the VFR800 swingarm. Or are you thinking of using the RC spindle in the VFR800's eccentric ?

So, you are using the RC30 spindle and sprocket carrier in the RC30 eccentric in your VFR750 ? Neat. The VFR750 eccentric is smaller than the VFR800's (and the same size as the Triumph's ~ see MrMatt). Rumor is the RC45 stuff fits in the VFR800 arm, but no one seems interested in ferreting out used RC45 parts to try it out around here yet.

Try David Silver Spares in Great Britain.

You want to put an 18" rear wheel on your VFR ? Ask Jamon over at http://www.blackrhubarb.com/ what the dealio is with Ducati and RC30 wheel interchangeability. The selection of OEM Ducati wheels is much better, unless you already have an RC30 wheel. The RC30 did not have a cush drive, so yes it will probably be too short on the sprocket side to work with your VFR750 cush drive.

Well, Yes and No. The Ducati brake stay is meant to slide on a fixed pin that is part of the Ducati's swingarm casting. I thought it would put some torsional stress on the linkage, but if I could have found someone to cut me a proper brake stay based on the Ducati part it would have been easy to make the sliding slotted portion longer such that it would have fit right along where the VFR800's brake linkage bolts to the swingarm. I would have had to make a few other changes to rotate the caliper to the bottom position of the wheel where it should be, as well as offset it to work with the VFR's rear disc, but if I knew someone who could have done that, putting a Ducati wheel on a VFR800 using a Ducati caliper would have been a snap. As it was, I could have fabricated a short linkage like in your first pic, but didn't want to rotate the rear caliper ahead of the centerline of the rear wheel, so I stuck with the longer linkage and modified the OEM Ducati brake stay and a Ducati rear rotor to work with the VFR. Maybe there was a better way to do it, but it's not like there was anyone around to ask so I did as much as I could figure out from the information I could gather, and just reasoned out the parts that were still blank. The VFR750 spindles I have modified wind up looking like this: PICT3153.JPG

Camera shy, I guess :lurk: IMAGE_343.jpg

Pretty much how you would fit it into a 3rd or 4th gen swingarm with the brake stay mount on the top of the swingarm. You can see the cylindrical spacer between the Ducati eccentric and the VFR750 swingarm. VFR800 has a different linkage which I found more complicated to deal with due to it's location on the inside of the swingarm. Modified a Ducati rear brake stay and the VFR torque rod ABS sensor ring attaches to the rear disc on the VFR800 spindle, so once that's gone, so is your ABS.

Please keep me in the loop on this one, via PM if necessary. Clearing the caliper is only half the problem in the case of the ABS model; there is a sensor ring mounted to the stock wheel which would not have been retained on the replacement wheel. Mounted to the stock rear disc....wheel has no effect whatsoever. http://www.bikebandit.com/houseofmotorcycles/2009-honda-vfr800a/o/m18431#sch612279 Part #7 RING, PULSER

Well, the 848 eccentric is different from the 1098/1198 ecentric, or at least the spindle is because you can use 848 wheels on the older 748/916/995/998 bikes, but not 1098/1198 wheels. There have been two other (supposed) people to my knowledge that have put either an RC30 or Ducati eccentric in their VFR. Have never seen actual pictures of a finished product anywhere. Two of the others out there (Swiffer, DouglasTheCook) on this site I had made here in Edmonton. BusyLittleShop did at least one conversion on a blue (and vomit-colored) VFR750 (not sure how else to describe the paint scheme...) that is now owned by a vfrD member. And MrMatt worked with SA1713 on the Triumph eccentric conversion for the 4th gen after I spent some time discussing it with him. At the time we were looking at fitting it to the 5th gen, but it would have required a cylindrical spacer and there may have been some other issues that I can't recall but it was quite do-able for the 4th gen (and most likely the 3rd gen since it's final drive doesn't differ that much from the 4th's design, if at all). VFROEM also put an NC30 final drive in his VFR750 which was fairly well documented on this site, but everything else is vaporware without pics.

At one point, Carrozeirra would sell you an adapter for $800. But I think they figured out pretty fast that would have allowed someone to copy it PDQ. Not that you couldn't make a copy if you bought the whole kit, but the kit price is a bigger deterrent for someone that might otherwise have access to a programmable CNC machine. Not that you couldn't just figure it out by looking at the pictures and taking some of your own measurements, mind you :cool:

Really ? The VFR wheel is a common mod for the Hawk GT, but it is typically done by modifying the Hawk spindle to accomodate the VFR wheel: Look for vfr wheel faq HERE

The Carrozeirra 'kit' would allow you to retain your ABS brakes as the spindle adapter offsets the wheel enough to clear the VFR800's 3-piston rear brake caliper, which is why they use a 6.0" wide wheel instead of a 5.5" Still a lot of dough :lobby:

What year VFR swingarm are you putting that in? Ding Ding Ding :cheerleader: We have a winner ! So many people confuse what people have done with (mostly) 4th gen VFR750's with what's possible on the 5th and 6th gen VFR800. You can sleeve a Ducati eccentric for the 800 as well, but you are still going to have to deal with the 3-piston rear caliper. Looks like I will be doing a spindle for another board member with a 5th gen this spring. They are going to fab their own brake caliper stay for use with a Ducati caliper, so those of you not afraid to delink your brakes may soon have a reasonable method of putting aftermarket wheels on your VFR800.

C'mon Sebastian. Just find a damaged 6.0" Ducati wheel and measure the offset. Buy a Ducati spindle off eBay for the measurements there, and combine the two to make the spindle adapter. I estimate the offset spacing on Carrozeirra's adapter to clear the VFR's rear caliper and centre the wider Ducati wheel to be about 6.35 mm. Turn one out of something cheap like plastic or wood to test fit and you're off :fing02:
