This is more of a general question than anything. I am not planning on running these front forks, but I am curious as to if anyone has. They are from a Korean made gt250 bike. Looks like they can be had for $70 tyd. I know they are cheapy, but with the increased popularity of using inverted forks on classic bikes, it could be an economical way to get there.

Again, please don't turn this into a "you shouldn't use a modern front end on an old bike" thread. There are more than enough of those already. Just curious if anyone has explored this option.

I will say, the offset looks like it would play nice, and they don't LOOK bad.... The axle looks small like our vintage bikes so that might play nice too....what's the brake setup like on them? These def look like worth a try for the money. I'll keep my eye out for more sets of these and maybe try a set out after I wrap up the handful of builds I'm currently into.
 
We have someone on the CX Forum who has stuck a set of GT650 USD's on his CX cafe and is very happy with it......especially the price

dare I say the rotor looks like it MAY be the same 6-bolt pattern on early honda CB's and Yamaha XS's......

if fork seals and upgraded (progressive?) springs are available....a set of these is certainly worth testing.
 
Brake Disc Information:
Inside Diameter Outer Diameter Holes Diameter
64 mm 300 mm 10.5 mm
Bolt Pattern No. of Holes Offset
86 mm 6 19 mm

damn. off by just a touch. CB and XS 6-bolt patterns are 80mm not 86.
 
i think the main issue to consider is if they are long enough.... as far as quality they should be fine but they are likely 2 short and 2 lightly sprung
none of these old bikes play well with being any lower, if anything you want the bike sitting up a bit higher for decent cornering clearance
 
a little googling says GT650 and GT250 hyosung forks are 30.7" long....not bad, considering a stock cb650 I just measured yesterday at 31" long....thats much closer than say GSXR forks or the like.
 
but there is more to the eqaution, need to consider that honda upper yokes are gullwing style, so these modern forks with straight across triples need to be an inch + longer minimum just to get back to stock height

steve f s bike is one of the best documented bikes around

and its a great handling nimble bike that steve enjoys a lot he has done a great job developing it over the years
 
I asked because I had a Silver Wing for about a minute (never told a sole until now) and it handled like a wood duck in soft sand. I looked for a throttle stop right away but found none... I also put those Fly Shocks on a CB and they have sense given up the goods.

Now I have done the Evelin Woodhead read of the build and can see he has done his homework and built a tidy road worthy machine, but I did read "looks great, looks cool, looks looks looks" but not much about the ride experience. I think it's a valid question and if it carves up canyons like a new electric knife through a hot turkey breast... lets hear about it man! hahah!! Not bashing anything, the bike is an awesome throwback cafe design with plenty of curb appeal.
 
He's got a bunch of YouTube vids of him ripping around the Old Road in his thread - it seems to handle pretty nice from what I can see 8)
 
has anyone with access to the hyosung forks measured the triple trees? the offset looks far better than that of the big name sportbikes like GSXR, CBR, etc....and if the clamps are the same as another set of forks at least the triples could be a fantastic solution to geometry issues paired with better forks possibly!

I'd really love to know actual offset and fork diameter at upper and lower triple clamp....
