Front wheel conversion question

Now that I've been drawn into this conversion exercise, just because it's there (damn you, WristTwisters!), can anyone tell me if the front wheel I am looking for (CBR or VFR) is symmetrical, ie both sides look like the pic below?

You will need an CBR F3 17" front wheel for the 6 spoke conversion. This will have you do the least amount of modifications. Fortunately the one I purchased came with rotors. You will need an F3 front axle and some spacers as well.

I'm not sure about the VFR though.

6 spoke is the ticket!!!

OK.

And are the hubs on a CBR wheel exactly the same both sides? The wheel I'm investigating is purported to be an F3 wheel, but I'm not sure that that's correct, hence my qn about symmetry.

The front wheel is usually the same on both sides, but it will have a directional (rotational) travel arrow, intended to be mounted the correct direction.

Thanks.

What I think I'm seeing [from the pics only] are slightly different hub sizes each side, although identical disc-mounting platforms.

They should be the same on both sides for the F3, yeah. Again, not sure about the VFR, but probably yes as well for the front wheel.

The wheel bearings are the same size for both sides, right? So the hub diameter should be the same.

One thing to note, if the axle is like my 599 axle, the left side (while sitting on the bike) has a larger diameter as the axle itself travels through the left fork and sets into the hub of the wheel, while the right side is smaller where just the axle travels through and connects to the right fork (of course there are spacers on each side). The spacers are what make up the difference between the right and left side differences on the axle (as well as the forks).

So you will also need to know if the axles are interchangeable as well, as that will depend on what forks you can connect to.

Thanks, Goog.

I'm prepared to undertake a bit of mix and match by the time I get to the axle / spacer part of the deal.

Another question - do the bolts holding the disc carriers to the hub screw into threaded holes, or are they nut-and-bolt? I can't tell from either schematics or pics.

Thanks.

Threaded holes in the rim, since you're coming from a land down under check these guys out, looks like pretty good pricing on rotors and such

Sorry, can't attribute this for the deserved hat-tip, but this twister found the 919 axle to be a fit, while others [eg Gibbonater above] suggest an F3 axle is needed:

"By mixing and matching 919 and f3 collars (see photo) all fit PERFECTLY!! The calipers had to be shimmed 1.5mm inward. Done.

Looking directly at the photo (right side of axle is on left) in order of sequence:
1) Mounting bolt
2) Right side 919 collar
3) Left side 919 collar
4) F3 collar, left or right will work
5) 919 axle
6) Above are shims (ss washers)"

Anyone got anything to add? Maybe it depends...?
