Fork specs

Figured this was as likely to get off topic as the last one so I started
a new thread..

I've measured the forks. I assume some of these values will be
irrelevant. For those of you tuning in for the first time, they're
upside down. Appearance is gold top then a stainless ring with seal,
then the stainless sliding tube then the axle mount, all one unit.

In terms of diameter, the forks narrow between the 2 vertical grips the
triple clamp has on it. The uppermost portion is 165mm in circumference,
and the lowermost portion is 170mm. The silver end is 190mm around, the
slider tube is 135mm.

In terms of height, as it is on the bike (I assume I'll need to fully
expand or contract it for perfect measurements):
Upper gold part 492mm, silver part 43mm (making an 'outer' of 535mm).
Tube is 127mm sticking out of the outer making the tube ad slider a
'neat' 666mm tall.
The axle part's 134mm high making a total height of 800mm.

The axle hole (love that ) starts at 773mm and ends at 785mm from the
top of the assembly.

Dry weight is 155Kg.

So (long shot..) does anyone know off the top of their head another bike
that has the same size forks from their experience ? Tho if you know how
to research that, let me know

 

I suggest that you follow these steps:

1. Get a service manual for the bike;
2. Buy/borrow a pair of vernier calipers;
3. Disassemble your intact fork;
4. Measure the stanchion[1] in all dimensions;
5. Go to that place where Clem bought his new Triumph fork
stanchions[2], and see if they can help you.


BTH
[1] The shiny chrome-plated tube. In your case, the "lower bit";
[2] Where was it again, Clem? I can't find the post in Google Groups.

 

Hang; what's damaged. Is there NOTHING reusable out of either leg?
If not; then you may as well just fit the front end off whatever you find
around cheap.

Ring up Alistair Maxwell at (dammit; what's that big wreckers out Penrith
way) and tell him your sob-story..
Is it
Liverpool Bike Wreckers

It'd certainly help if you could match your forks to a Jap bike. Go to the
dealer and have a wander around the used bikes and see if anything matches.
(And if so; look here: http://www.bikebandit.com/oem-parts )

If it's just the shiny inners you want then follow BTs advice.
This is where I got mine but they don't list Hyosung:

When mesuring round things in engineering, it's customary to quote
their diameter, as measured with a set of Vernier calipers, not their
circumference.

Also, when trying to source secondhand parts, it's customary to hassle
wreckers with repeated phone calls rather than to leave messages.

Hyosung have been selling far too many bikes to n00bs over the last
couple of years for quite a few of them not to have ended up in
wreckers by now.

Which wreckers have you called directly and had them tell you over the
phone that they positively *don't* have a straight forkleg for the
GT250/650 (bet you dollars to doughnuts they run the same front end).

This business of trying to transplant a front end off something else
is so far down the list of absolute last-ditch desperate options to
try, it sits below donating what's left of the bike to the local patch
club for their next bonfire.

There's bound to be a forkleg out there; look harder.

 

Yeah I did, thanks The Biker. That was where I found a most helpful
gentleman who promptly replied to all my parts requests .. and even sent
me a parts manual. My initial quote for a single left leg was 350us but
with currency the way it is it's likely changed in the weeks since I
spoke with him. Once I factored in exchange GST and the rest of the crud
that comes with importing it didn't work out much cheaper even tho his
mirrors were 35/pair and the local could only get them for 'only' 130+..

I'm coming close to just paying the local dudes to do it all or at least
get the parts and have me put them on (then ride slowly to the shop and
get them to check my handiwork .. mechanic I ain't (but I can change a
clutch cable..) )

 

What.. threaten to go public with the RRP of the parts which they sell
to the public? **** ME. A whisper of that and they'll be knocking down
his door with two sets of forks. That reminds me.. I have to tell the
folks down at Ferrari that I'm going to ACA with their new car catalogue
if they don't give me a free car...

Changing a clutch cable is rather simpler than bolting in a fork leg.

Unless you have a torque wrench, know how to use it, and have the
appropriate torque settings for the bolts involved, I'd strongly
recommend that you let the local shop do the job.

I have heard that the metallurgy of the Hyosung isn't that flash, and,
if you start stripping threads or breaking bits, you might never get a
going bike.
