Hey all, I'm looking for a front wheel that will fit an old Suzuki GT750
front end. The original GT750 drum brake systems are out there but pricey,
I'm just looking for something that will fit. I believe it's a 7/8" axle.
I don't necessary need to the rim and spokes, but I am looking for the
entire brake/hub assembly. I've got the original one for my Triumph but the
axel is 5/8" and is a bit short. I suppose my other option is a longer 5/8"
axel and axel spacers for the forks. Anyway, thought I'd check to see if
anyone in here has anything taking up space on the shelf in their garage
from way back in the day.

Shirley some drinks are in order.

Axe sually, it's likely metric, but it's about 7/8".

Ahem!

Suzuki is metric! The hard part will be making a caliper mount for a
proper disc brake. How much room do you have between the legs? Probably
be best to use a matching axle unless it is just "through bolted".
Usually there is a pinch bolt on one side to allow some movement so the
forks don't bind up.

90 degrees here and humid, thanks for the refreshing beverage.

90 here too , but the heat index sez it feels like 102 . Silly me , out
torchin' some shapes in this heat .
I have one 19" wheel , spoked , with a disc on it . Les gave it to me , if
you want it , it's yours (Tud , that is , Rick don't need a wheel) . Dunno
what it's off , neither did he . But we both thought it would fit a CB 750 ,
which it won't .

Actually, if there's room, getting a caliper mount fabbed up isn't a big
deal. FabKevin (if he's not busy running around to various gatherings)
does a really fine job of flat sheet fabrication of stuff like that.

Yeah, yeah, I covered that in my followup post. I'm guessing 20mm.

Getting a little personal ain't cha?

There is 5" between the two lower legs. The distance between the outside
edge of the axel holes is 8" and the inside distance is 6".

I don't see any pitch bolts, and I also don't know what the bolts on the
right and left are for.

Here's the original front Triumph wheel, the axel is shorter than 8", is
narrower than 20mm and looks like it has a spot for a pinch bolt.

Definately a Suziki front end:

Fits nicely on the Triumph though:

I haven't really considered a proper disk brake, I was just hoping to get an
old jap drum that I could fit on there without much trouble. I was the
correct one for the bike somewhere on the internet, it was far from like new
and they wanted over $300, no thanks. I think I'll hit one of the
independant shops next week and poke around and some of the old junk they've
got.

Thanks Snag. I'm going to hunt around for a drum to keep things simple, but
if that changes I'll let you know.

Side bolts are for fender braces , upper center should be fork oil drain .
The two coming up from the bottom clamp the axle .
Are you sure that Suzuki front end didn't mount a caliper ? Others have
mentioned FabKevin ... and disc brakes are a bunch better than drums .

Seems low for fender mounts, but doing a quick search I can see that you're
right, and in the picture you can see the drum brake it used, 4 shoes in
that sucker.

Tud, wasn't your father one of the guv'ment advisors who
helped introduce the metric system in Canada ?

BTW, we have a family vacation planned for next week and
one of our favorite pass-times with the ol' man is gettin' him
riled up by dissin' the metric system :)

WHOA. I'll buy that hub off ya. I have a '68 hub on my '70 bonne and
that looks like the '70 style hub with the better brake cable
routing.

Did he really? I had no idea, although I know he greases me out every time
I say kilometer wrong.

Or.....we can hit some indy shops that have salvage bikes and you can buy me
the hub I need and you can have the Triumph one. :-)

Will mine work with your Bonne lower legs? I think most drum brakes have a
brake stay in the form of a bolt on the hub that connects to a bolt on the
lower legs, the one I have actually has a slot and there's a corresponding
piece on the lower leg that slides into the slot. You may as well take the
whole front end since you want the triple trees as well. The upper legs are
shit, but the rest might be usable.

Yep. You were probably too young to recall Mom sitting us in
front of the TV to watch Dad getting interviewed about the
"great and glorious metric system". Mom tried to take a picture
of Dad on the tube but of course she used a flash and ended up
with a picture of an gray screen.

Yep, there is a bung on the lower legs that engages that slot.

Indeed I was too young, I have no recollection of that at all, did they have
subtitles?

Should work then. I haven't inspected it too closely or opened it up, but
it should clean up pretty good.

I found out that a front wheel from a 72 GT550 will also bolt into those forks.

Otherwise I would look at a dirt bike wheel with a disc brake, I think
you will be able to find one with the same axle setup (dual clamshells)
width might be the challenge.

Which forks, the GT750 forks I have that are setup for drum brakes? If
necessary I could switch the lower legs with something newer that will
accept a disk brake setup, but I'd rather just find a drum brake setup that
will work with the GT750J setup I've already got. I think I'll need to
check some local places that have stock of old salvaged jap bikes before
resorting to E-Bay or switching out my replacement forks.

Yes, the GT750 wheel is is a 4 shoe brake and very desirable to the
vintage racers, thus the high replacement price. If you are lucky you
may stumble across a less than knowledgeable seller of a 72 GT550 which
shares the same wheel. A scrapper will not be less than knowledgeable
source as they should know their business.

Which leads us back to the aforementioned dirt bike wheel (probably
less money including caliper and master).

But to back up to what you said previously, a GT550 drum brake setup will
fit the '72 GT750J forks? I'm not adverse to a dirt bike wheel either, but
if I can find something that will work with the forks I have then that would
be my preference.

Holy shit, you ain't kidding! I was watching one on E-Bay and it went for
$566. It'll be much cheaper to buy different forks that'll take a disk
brake, the wheel and the brake caliper, although the shipping will kill me.
