Hi Folks
New here, new bike, missed my old 3CV and now have just bought a modded 3XW and would like to know what you think these forks and swinger are off. Seller didn't do the work and said they were from an R1 but I can't find that brake caliper in any R1 pics. Might be R1 with different calipers? Or are they off something else? I took the pics in a rush in cramp conditions, sorry they aren't a bit better. Pic of top yoke too just so you get the full picture.
Many thanks
Chaz
I might be wrong, but that swinger looks a lot like Pats T-ace swingarm?
Good eye Ryan, I was thinking the same.....but the 97/98 YZF1000 (aka Thunder Ace) had a conventional front fork, so maybe the back came off a different bike from the front.
Here are the specs on the YZF T-Ace rear swinger: http://www.fjmods.co.uk/MarcRittner.htm (http://www.fjmods.co.uk/MarcRittner.htm)
I have no idea where those front forks came from.
The axial mounting of the brake calipers puts the forks pre 2005. After '05 it seems that most USD's had radial mount calipers....speaking of caliper mounts, I would like to see a better picture....something looks weird, I don't see a lower support arm on the caliper.
Cheers

Thanks for the input Pat, Ryan, I'll get a better shot of the front brakes up here hopefully later today. Hopefully "weird" doesn't end up meaning it's been cobbled together/bodged.
My 93 yzf 750r had six piston calipers like that. Can't remember the swinger but I think it had that adjuster.

More pics of front and rear. I got out between rain showers! Hopefully these are clearer and make identification easier.
Thanks
Thanks Chaz, yep, the back looks to be a TAce but the front....hmmmm
I know it's not the FZR or the YZF750 USD's because I have those USD's
If it were a 2003 Yamaha R1 front end it would not have Tockico 6 pot calipers, but gold spot mono blocks.
So.....the axial mount Tockio calipers puts it at pre 2003 the large diameter front axle makes it.....
I think it's a Suzuki....but I can't match it up with the factory photos.
I know 2 Suzuki USD experts, Dan and Fred, what do you guys think?
I think I found them, they look to be Kawasaki ZX-7R forks with an aftermarket fender.

GSX-R? (https://s2.qwant.com/thumbr/0x380/5/f/22c8bd33de4a617bd282b92cc4d4a546ddd4787dbf662d6f39f04eed7d01d3/suzuki-gsxr-600-2003-1.jpg?u=http%3A%2F%2Fmoto.zombdrive.com%2Fimages%2Fsuzuki-gsxr-600-2003-1.jpg&q=0&b=1&p=0&a=1)
edit: oops, not even USD... nvmnd, I'm on hour 11 of an overtime graveyard shift.

Thanks Pat!
Would/should these have been re-valved for the extra weight of the FJ?
As an option are they ok?

Rick, you ride your FJ to work, right?
Be very careful going home amigo.....

Yessir, and Roger Wilco. I usually grab a quick nap before departure and crack the visor a tad. The new Pirellis make for a little adrenaline boost as well.

A quick browse shows the ZX7r adjustable USD and 6 pot calipers ran from 1996 until 2003.
According to the Race Tech website the stock ZX7r fork specs for those years show the fork uses a .85kg/mm spring.
You should be ok for solo riding (how much do you weigh?) but in my opinion too light if you carry a passenger and luggage.
I have .95kg/mm springs in my USD's and I think they are perfect for solo with luggage.
The big question, how do the forks feel? Set your sag. If they feel good with no excessive dive, leave them alone.
Cheers

Throw some rain or fog in the mix and you will have the perfect trifecta, wet roads, new tires and fatigue.
The Sunday traffic will be the bonus.

I leave at high noon, so it should be all good. It's clear skies up here.
Chaz, on your fender, see the Allen head for the fender mount on the front lower leg?
See how it's Perpendicular to the axle?
Now see the mount screw on the stock ZX-7 photo? They are different. Parallel to the axle.
The difference might have something to do with your aftermarket CF fender.
That's the only detail I can't reconcile, everything else matches.

I need to have a proper ride on her to give you a decent answer to how they feel, which hopefully will be sometime later this week as she has a few other bits to sort out first. I've must read up on the whole sag and suspension set up process too as it's something I've not had to do before. I weigh about 85/90kg i think. Most of my riding will be solo, but I will want to take passengers occasionally, though just on short trips rather than touring. I hope to do some more solo touring too so I guess I'll be upgrading them if they haven't been done already. I'm still trying to get in touch with the owner that did all the modifications. Hopefully they'll remember what, if anything, they changed from standard.
I do know she tends to tip in quite hard on slow turning, which took me by surprise. Guess I'll be checking the steering head bearings to make sure they are ok. Other than that I'm not sure what that might be other than the bike steers a lot quicker than standard with the USD's.
Thanks again for your help Pat, very much appreciated.

Even the discs are identical to ZX7-R discs - I reckon Pat's on the money with his suggestion on the front end.
The steering change is more likely down to something like the rear ride height, possibly shorter front forks, lighter wheels and different tyre profiles and sizes, than being down to the fork springs.
BUT, dropping in suddenly might also be something as simple as low front tyre pressure.
I've got a FZR 1000 USD front end on my FJ and it has 0.95 fork springs and Bridgestone BT023's and the front end feel and steering are much more neutral and consistent than with the original FJ front end. Hopefully you can it sorted and feeling good simply and quickly Chaz

Thanks, rear ride height could very much effect things! Tyres are 36/42 so shouldn't be that. Lots to do to get her sorted so I'm happy with her. I'm just hoping I don't have to change the exhaust cans! That is a whole new can of worms which would involve re tuning.
