hawk spindle that i universal (stock and vfr wheels)???

[jaysun0ne]

has anyone done it???

i mean if you used the holes for the brake disk and made the pull double duty when you had a vfr rim and the drive pins have room to stay and then you could change out the wheel and use a metal bushing to fill in the gap on the center hole i was looking and i dont see anything wrong with the idea anyone else???

[SMF]

to do it properly you'd have to have the vfr wheel machined to match the hawk's setup. anything else seems a little sketchy since you'd have to turn down the radius and the length of the spindle to fit the vfr rim, then compensate for that lack of material when you mount the hawk wheel.

Personally, I'd just find another spindle if I wanted to keep the stock setup as well.

I've done it.
I keep the stock Hawk spindle and had the center pocket of the VFR rim machined deeper to clear. Right now my drive pins are rplaced with 2-piece SS wheel studs. It is a bit of a pain to change back to studs, but I occasionally do. I'm working already on the details with another member to use the disk bolts as you suggest.

hay cool


not the way i would have went about it but like they say "theres more than one way to skin a cat"

my lathe cant turn something the size of a rim (or i would have just made my own rims) so i was thinking about two unmodified rims
the more i think about it. your way (modding the vfr rim to fit) is better than making a alluminum bushing to fill the gap when the hawk rim is on.
i plan on turnning down my spindle some time this week. if it fits in the lathe, i think the throu hole on my chuck is to small, well we will see.

hay were did you get those bolts i need a set.

also is this something you guys allready had in mind?

[NT696]

I use the VFR rim all the time, I rarely change it back to stock. The VFR rim locates using the smooth part of the wheel stud. No need for a bushing to the spindle. The VFR spindle has a round boss that does the locating, but the Hawk spindle of course is different.
Those pins are custom, I had them machined. The Hawk spindle has 10mm holes to press the drive pins into. The 12mm studs needed for the VFR rim, meant custom 2-piece studs to avoid opening up those holes.
The Hawk spindle is case hardened on the surface, as it has been ground in spots to run against the needle bearings.

-Just to see if it clears the rim, I removed the brake disk nuts and loosely installed my custom VFR studs, so I had pins and studs on the same spindle:

(It does in fact clear the Hawk and VFR rim casting)

Wow that bolt into the bolt setup is scary! I would not want to be on the bike if it fails!

If you want to be a bit safer way, I only use factory Honda lugs on my conversion.

Just another option for you.

Rod:
You are absolutly right, the Honda studs are strongest, no doubt.
I did it 2-piece to keep from machining the spindle. (Modify the new parts, not the originals)
It is actually pretty safe, the bores of the pin and stud nest together tightly. I would'nt ride it if it were not safe. 25,000km so far.
There is probably a few other methods to accomplish the same.
Have you heard of anyone machining the outside face of the VFR rim to accept the Hawk nut washer? -Better yet anyone have pics?

[jaysun0ne]

allright it does work, just looking at them next to each other the other day, i thought it would

there are so many was to do this mod its cool to see it can be taken a step further.

my next question is about ducati rims ??? is mounting a duc rim just has simple? is there an off set problem? can it be fixed with a spacer like the vfr5.5 rim?

im just woundering because a few months ago on ebay i came across a set of custom limited run ally rims for a 919 i think, ahh i cant remember the exact model (it was the race only model) and i thought they would be awsome on a hawk but hesitated because i didnt know how much work it would be to mount them or if its even possiable, plus they where 350 before shipping. i have seen hawks with stock duc rims on them in the past.

and im not sure but i think i have seen pictures of some kind of center nut on the vfr rim, wile on a hawk. i dont know enough about vfrs to know if it was a stock vfr center nut threaded into a hawk spindle, or what.

or maybe it was a custom nut and if you would like one made out of alluminum i might be able to do that its a small enough part for me to make. i will use my bike as the ginipig and post a pic here in a few weeks when the rim is ready to mount to the arm again (my project is one of those long term deals) hay nt696 wich vfr rim you running? i got the rounded style 5spoke rim. my least fav. if anyone would like to trade im polishing it out right now.

[jaysun0ne]

also i need to find the lug bolts

does anyone know of a place that sells a set that does not have to be press fit???

nt696 i would really like a set like you have

maybe i could modifly a set do work like yours

[Hiper Form]

I see you ground out some material in the VFR rim. If you switch the nut size from the stock 17mm out side to a 14mm outside but same ID then you won't have that problem.

I think it would be safer to get a extra spindle and mod it. There is a reason why Honda did not run smaller lugs. I know it has not failed on you so far but what if you did? I know someone that was killed on a 916 when his carbon wheel failed. I just don't think it is worth the risk when you can find an extra spindle for less than $100.

Never crossed my mind! -That would have saved a lot of grinding and test fitting to be sure. A few others have noted this interference problem, that is a better solution.

I think it would be safer to get a extra spindle and mod it.

The whole point of doing this was to not mod the spindle. Yes, two spindles will also get the job done, but then you have to spend a few hours swapping spindles if you want to change rims.

I'm not saying that the 2-piece studs I use are better than everything else out there, not at all. The question was whether it was possible. It is. I design machinery for a living, I made them very safe, as I am the one who is using them. I inspect them every season, (four years so far) and am also working on a better, even stronger version.

One-piece 12mm studs will surely need to be press-fit. This can be done using a heavy series nut and hollow spacer if you dont have access to a press. You will need the spindle holes opened up to the right size first, as the drive pin holes are 10mm diameter.

jaysunOne:

nt696 wich vfr rim you running?

Mine is a 5.5" 5-spoke from a '99.

is there an off set problem? can it be fixed with a spacer like the vfr5.5 rim?

What spacers are you referring to?
The VFR rim has the same centerline offset as the Hawk rim. (19mm) Any spacers will put the wheel off to the right.

nt696 i would really like a set like you have

maybe i could modifly a set do work like yours

I would be glad to share if you are interested, like I mentioned before I am working on a newer, better method.

i read that somewhere. a guy was runnng a 5.5 with a 180 tire and to keep from rubbing on the swingarm he used a spacer. i cant remeber where i read that. that would be a strange ride to have the wheels out of line with each other.

i think im just going to go with regular old press fit studs. but i really do like your setup. maybe down the line when im putting together a track bike

Ye gads! -- strage ride indeed.
I run a 180 on the rear, and had to give the swingarm just a little love from a half-round file for running clearance. (see picture on 160/170 tire post)

Help me please.
I can do any lugs and nuts(I work in machine-building factory) And to temper her as necessary. But I do not know sizes. Send me exact sizes.
I certainly can purchase a Hoda set, that will cost approximately 50 dollars plus delivery 30. Price of similar screw-bolts in Russia is 2-4$
Sorry my english.
