Hi there,

Does anyone know if the stud pattern for the VFR750 and the VFR800 are the same? I would understand if there is a difference in offset. I have a SSSA off a 95 VFR750 which Im placing onto my 99 Blade. I am curious if the VFR800 rim will fit onto my VFR750 SSSA even if I require to make a spacer etc...

the only difference between the rim is:
97 and under is 17x5' and has groves in the back which fit the hub
98 and up is 17x5.5" and with minor machining from back can be installed.

I have a 94/97 Swing Arm with a 5 spoke VFR 800 wheel fitted to a 94/95 blade...

We did not machine the wheel - but machined the Brake Caliper Nuts to fit in the space where Honda sit the bolt heads. I bought new dome head allen bolts and machined the heads down a little further.

The bolts have effectively been reversed, and now sit flush so the wheel does not need to be machined....

This was easily done (and only took a few minutes with the added advantage of no need to damage (machine the rear wheel). In order to do this you may need to loosen the axle nut so the stub assembly (holds the brake disc and wheel) can slide out of the holder a little (should be easily done)..

I did this whilst cleaning and rebuilding the hub before final fit.

hey saxon those bolts are some special or you bought them in the hardware store?

Sorry for delay in replying - been on holiday!

The bolts were standard stainless button head allen bolts. I have just skimmed them down using a lathe so the head fits flush.

You should be able to get them from any good fastener stockist.

Thanks mate

, one more question: You wrote that You changed brake caliper bolts. Im guessing You meant those 4 brake disc bolts that go in to the hub am I wright?
There are no problems when You reversed the bolts?
Im putting VFR 750 swingarm into my 97 blade with VFR 800 rear wheel so Im asking :thumb:

Ah ha, you are correct, I meant the brake disc mounting bolts. I have done this to my 94 blade using a 94-97 VFR750 SSSA and VFR800 rear wheel. I have had no problems.

I will try to post some other pictures over the next few days to help.

That would be great mate

I dont know how strong bolts should I bought

see if you can download this pdf... shoudl help explain what was done to the bolts. For bolt strength I just used standard stainless high tensile steel bolts....

Let me know if this helps....

Now I understand mate :thumb: You have also skimmed nuts

Many thanks for Your help!!!

These pictures may help also.

On the first picture (from the left) you can see that the nut has been "skimmed" so that some of it fits inside the depression within the disc.

This is important as clearance is small on this side of the disc. This way I kept maximum number of threads (the nut is still standard length) but was able to fit it inside the clearance available (which would not have allowed the standard nut).

On the second picture you can see that the bolt has had its head "skimmed" so that it fits flush inside the depression within the axle.

Good luck

I'm in the process of doing this too on my '98 Blade.
Thanks for the infos, but I have a question to ask:

Would the tyres line up with this mods?
As I read, a 20mm spacer will be needed to fit the 750 swingarm to the frame (right side), hence the rear wheel will move 20mm to the left.

Would it be better to use a 10mm (hubcentric) spacer instead to account for the wheels alignment?

Please correct me if I'm wrong..

Cheers

I used a 94-97 VFR750 swing arm.

I believe that I have managed to "line up" the centre of my wheels by using circa 5mm of spacers (two largish washers) on the left side of the arm (viewing the bike from behind the number plate).

I find that the bike feels different, but behaves still so no worries.

The 20 mm spacer to the right works, but in reality could easily be 25 mm or possibly 30 mm. I have used a 20 mm spacer (on the right of the swing arm - viewing from behind the numberplate) no worries.

The issue (in my view) is lining up the centre of the rear tyre to the centre of the front tyre, whilst maintining the correct alignment on the chain (it should be straight front to back).

In order to keep ride height similar, I needed to manufacture new linkage triangle plates also - so measure seat height from floor before you remove all the original swing arm etc..

Good Luck :thumb:

Hi

You're quite right it's 25mm spacer on the right side of the swingarm pivot, would the sprockets line up with this? If they do then that's great because I don't want to grind off materials on either frame nor swingarm.

Yes, the centre of the rear wheel aligning with the centre of the front wheel is what I meant. CBRRT apparently measured 18mm offset on the 750 rear wheel and he had to use 30mm spacer to fit a car wheel with 40mm offset to line up the wheels centre to centre. If that's the case then the original 750 wheel would have moved 11mm to the left (viewed from the rear), hence a 11mm spacer (hubcentric) between the hub and the wheel would line the wheels centre to centre. I wonder what's the offset on an 800 rear wheel? Hmmm.... same as 750 wheel?

These are just theories from searching the net as I don't want to be wasting hard earned monies on trial and error, also the bike must not be taken off road while mods are in progress or I won't get to work...

The sprockets alignment is not too bad, and certainly pass MOT's. I have made no modifications to the frame or swing arm to fit the swing arm, just used washers and spacers.... BUT my blade is a 94/95 blade.....

PM me some contact details if you wish to discuss in more details.

Just for reference, the VFR rims use a 100mm stud spacing between them measured on centre.
