RC45 rear hub swap

I looked into and contacted Carrozeira on that very subject, LOL they where also very closed lip about it. my question was more in regards to would the set up they use work on the 750. still they wouldn't fill me in on the details, or they didn't know. when I asked if I could buy the hub axle setup, figure I would return it if it didn't, work they said it only came with the wheels, again go figure.. Gee only $2600 for the pair. you wouldn't happen to know anyone that has bought those?

 

Ok, here's what one of the VFR sites has for swingarm dimensions:

Honda VFR ('90-'2003+), Hawk, RC30/45, NSR250 all use the same relative rear wheel offset. i.e. mix and match wheels amongst the various models and so long as the spindle face is unmolested the wheels will remain centered.

Nope.

I figure once you bought their adapter you could copy it and/or use it with other wheels, which is why they don't want to sell it by itself.

 

There are some serious issues with swapping entire swingarms, mostly related to incompatible combinations of linkage mounts top/bottom and/or frame vs. engine mounting

For instance, the MV swingarm has the correct underside linkage but mounts to the frame. Not so good for an 800. There was a guy in New York (guukan.org) that was working on putting an MV750F4 swingarm on his '92 VFR750 but I think he eventually lost interest in it after two years. Looked promising but obviously a lot of effort.

Digging through the data you can see how certain combos (NC30 in VFR750) of eccentrics and swingarms might work, and why others (Ducati wheel on HawkGT) don't without some fiddling.

Looks like the MV eccentric is roughly the same dimension as the Ducati's - that is, the right width but requiring a cylindrical spacer for the VFR800 swingarm. Right diameter but too wide for the VFR750.

 

I'm not suggesting he run out and grab the first ssa he can find (he and I have had numerous discussions on the topic) BUT if you can find one that works as built it seems obvious that is the way to go. Looking at the list, you can see there isn't one so he will have to do what you did. BTW the 750 has a frame-mount swingarm.

Actually, the numbers in my prior post are from guukan.org, and I think I too would lose interest in a 3G if I acquired an RC45.

 

Which is why that swingarm works on the 900RR, whereas you need an 800 swingarm for an RC51, VTR1000 or CBR929/954 conversion.

 

This sure does make the mind work. yes this is a Carrozzeira rim on a VFR

 

Carrozzeira is not the first place to supply a single-nut conversion for the VFR.

A Dymag distributor in the US called SuperbikeRacing used to make one for Dymags. It didn't work for the 750, though.

Other shops/people have made various adapters. Some are still available, most are not. The one other person I know that will make you one will charge you $1500 for it.

Personally, I think $2600 for the wheel set with the adapter is a fair deal.

 

RVFR:

Why such the intense interest in this?

Just curious.

RVFR - Been a while since I've posted here, but hey there. I've been interested in doing the single nut conversion for my build ever since I started it. I've talked with Safe-T before and looked up the info about the hub conversion on vfrdiscussion as well with little advancement on the issue. Almost none of the spindle conversions are available any more. But I did come accross some good information you might find interesting. I came accross someone who like me did a SSSA conversion to their bike. But he found a way to put a 3 spoke Ducati wheel (748) onto his ZX7R with a VFR swingarm. Now this is where it gets tricky. The duck wheel has s different hub offset. So he had a plate (3mm I think) made to use as a spacer and some new lugs made with the same additional length and press fit the hole thing onto a newer Triumph spindle. There is another piece need for the spindle to be accepted to the VFR hub, but I'm waiting on a pickture from the person for that info. I'll try to post up a picture tonight of what he has sent me already. This would make the conversion a lit cheaper than buying Carrozzeira rims.

Buy the way, the 749/916 family and 848/1098 family spindles are completely different diameters so they are not interchangeable.

Here are some pics of my build. Took me 1-1/2 years to get to this point. But so far the only original FZR parts are the frame and engine.







I had everything finished to the point that I could ride it and enjoy the rest of the season, but I found out the hard way what happens if you don't torque down the spindle nut all the way. The carrier and sprocket went skipping down the road without me and distroyed itself. Luckly nothing else happened. I'm in the proccess of fixing the mistake and I've designed a slotted nut to take the place of the notched nut that Honda uses. I'll drill the spindle to take a cotter pin so the nut will never back out again. Now I just have to get the nut made.

 

Ya know it's, just well Hell one of those things that just bug me. that and be cool. and that idle hands are not happy and that since a NEW V5 viffer ain't any where to be found, figure why not


Cad; don'ts ya gota love a project. nice bike there. Thanks for the info. I'm leaning now to just go ahead and get the Carrozzeira package only if they back it up with it being returnable if they don't fit, as they are actually made for the 5-6th gens then maybe I'll also see just what it is they do to make this happen. Safe-t you're right $2600 isn't really all that bad if it's a plug and play.

 

Ooo lookie lookie what I just found

 

Go for it, RVFR. We all wanna see your modded VFR!

 

Definitely let us know about this, as I'm very interested in the outcome as well!!!

 

I hear ya on NOT gtting the new VFR. But I am just too practical to drop the cash-ola for something like this.

I enjoy watching others do it since I don't have the talent. But if I had 2600 to burn. A SV650 track bike would be sitting in my garage. God willing, it will be in the next few years:smile:

Will do MD. Mmmm, gee, it doesn't just reach out and grab you? I mean come on now, it's so everyday.








LOL RC45

 

That's an RVF wheel.

I can't E-bay from the office, or I'd look if that's where it's listed.

I'm with Bubba on this one. I'd never pony up the time or money to do this, but would love to see it done.

 

Not on Ebay, actually I tripped over this gem on a race shop site that tricks out NT650s. Was doing some research and I'm finding the the NT looks to be using or maybe uses the same hub except that wheel is installed with a single nut. Go figure.
I Know what you mean about spending the $$$. I on the norm don't go to far with adaption, but this time around I'm thinking Hmm as one no one makes a bike like ours and it needs very little to bring it up to date. Add in I'd spend way more on a new machine and get probably get no more fun than what I'm all ready experiencing. I mean it really is hard to be any better than this. less brakes and looks. I could just park the Viffer and go get a 1098 Mmm whats that $20K or if i was lazy go get a 091000RR for what $13K, so figure a little spent here wouldn't hurt a thing, plus I'd have a one of a kind to boot. It's still all on paper, I'm not going to mess with mine till I have everything in order and know it'll work, last thing I want is a winter project that takes 2+ years.

Now your just rubbing it in. Where did you find unobtainium? Gotta a deal with Larry?

Wanna sell it? Cheap?
