Title: Dual disk front forks
Post by: magicGoose on August 18, 2005, 04:07:28 PM
Is there anybody with a Euro spec 400 with dual discs who would be willing to take a couple of measurements for me? I need to know 2 things. First, do you have 41mm forks like the North American version, and secondly, what is the fork spacing. Any measurements for the fork spacing will be OK, like inside to inside, outside to outside, centre to centre, whatever.
I am looking into getting a dual disc setup, but I don't want to swap the triple tree because I have custom bars similar to the Suburban Machinery ones that I want to keep. Ideally if I can find a Suzuki with dual discs, 41mm fork tubes, and the same fork spacing, I will be able to slide in the new forks, add new calipers and rotors, and I'm set without futzing with wheel spacers and such.
Also, if anyone has done this, or tried it I would be interested to hear your thoughts.
Regards,
Steve

A gsxr 400 gk73a has the front end you want as does that other bandit you said these share the same front end no tree replacement involved

Post by: Farre on March 08, 2006, 09:52:30 AM
is it possible to use a gsxr400 front end with the disc of a single? I'd like to convert to double discs, but i don't have the green to do it all at once.
I'm doubting about this, becuase i think i read somewhere the dual discs are smaller than the single disc type.
Ultimately, if the single kind fits on it, then it would be possible to fit 2 single discs on it, giving much greater braking, maybe overkill though..

Alex, when you swap front ends, get a complete one, then you'll have all the parts to upgrade the forks and brakes at the same time.

Alex, if I understand correctly, you want to swap the forks but initially keep the B4 front wheel and rotor? I think the problem you will run into here is if the rotors are different sizes, the caliper mounts will not be in the right places and you will have to make adapter plates to make it fit.

Uhh, sorry Red01, i already have the gsxr forks at home, but i'm missing the rotors and the calipers.
MagicGoose: That is indeed what i would like to do... hmm, i was already worrying about that.. The wheel wouldn't be a problem, i've read elswhere that the only difference is just untapped holes on the other side. I should check one time the place of the caliper holes on both forks (b4 vs gsxr400), if there identical then i can place everything from the b4 onto it. The rest should fit, i don't see why not..

Alex,
I will be interested to hear about the caliper mounting. My stock calipers have the mounts really close together, different from any other Suzuki I have been able to find.
Another thing to think about is the axle and spacers. The Bandit axle threads into one fork leg, rather than having a nut like many other bikes. Is the GSXR the same? If not you will need a GSXR axle as well.
I have also read that Bandit wheels have unthreaded holes on one side, but mine does not have any holes at all on the side with no disc. Maybe this changes with the model years, mine is a 91.
Do you have older conventional GSXR forks and are keeping your triple trees, or do you have USD GSXR forks and will swap triple trees as well?
Steve

Steve - if you read Alex's earlier post, he has GSXR400 forks.  IIRC, they're very similar to the B4 (41mm conventional) but adjustable for preload and obviously are set up for dual disc brakes.
Title: Dual disk front forks
Post by: magicGoose on March 09, 2006, 01:29:42 PM
Uh... I THINK that he has a stock B4 and a set of GSXR400 forks that he wants to install while initially keeping his stock rotor, caliper and wheel. Later when he has the money he wants to install a second rotor and caliper. He is asking if his bandit caliper wheel and disk will fit up to his GSXR400 forks.
(or am I missing something here, as usual?)

Sorry, my fault.  When you asked about conventional v. USD, I thought you were thinking he had 750 forks or something.  You got it right.  

BTW Steve - do you have a plastic cover on the non-disc side of your wheel?  I've never taken it off but Jay thinks the unthreaded holes are under there.  I think Thief tapped and is using his stock wheel with his dual-disc Kat f/e.  Yo Chris, were there holes on that side or did you have to drill it out b/f tapping?  

Pic of plastic cover...

Exactly what MagicGoose said. I have the triple trees and forks.
I would like to use the gsxr triple trees as well, because in the accident in december it seems the stock has been bent a little.
The other questions you've asked made me a bit anxious... i don't remember if the axle system is the same or different, same about spacers..
About the unthreaded holes in the wheel, i've read in another thread it's hidden under a sort of strip. mine's also a '91  :wink:

Rob,
Yeah, I have the plastic cover on the non-disc side. You can actually pop it off with a small screwdriver without removing the wheel or anything. It will move enough to see inside the hub. I have bosses where the holes would be, but no holes :sad: Because of this, I bought a Katana front wheel for my upcoming dual disc conversion.
Alex,
I don't mean to rain on your parade here, it's just that I have been looking at this kind of stuff myself lately, and these are some of the problems I never foresaw. I am currently thinking about early GSXR750 forks ( because we don't have GSXR400s over here :crybaby: ) and the axle mounts are completely different.
Regards,
Steve

With the GSXR forks, go with the GSXR wheel & brakes, so you get the entire front end assy.

just checked the forks i got here. axle is identical, but caliper mounts are different...Sooo, anybody got some discs and calipers for sale? No rush, though

I know 6 piston calipers fit on there. So go from there.

For the discs, try looking in the EBC catalog here:

http://www.ebcbrakes.com/Assets/ebc2005ukmccat.pdf

Find the replacement disc for the year of GSXR forks you've got, then cross reference them to the other bikes that use the same discs, then off to e-bay to find some discs from one of those bikes.

Done that and just to help everyone out a bit i'll post my findings here:

GSF 400   S/VS/V-V/VZ-V Bandit       95-97
GSXR 400    J/RR/RAK    (GK73A)  88-90

RF 400     RP/RR/VR/RT/RVT/RV-V       93-97

GSF 600    S/T/ST/V/SV/W/SW/X/SX/Y/SY/K1/SK1/K2/SK2/SK3/K3/K4/SK4 Bandit 95-04

RF 600      RP/RR/RS/RT/RV                 93-97

GSX 600   FK/FL/FM/FN/FP/FR/FS/FT/FV       89-97
   
GSX 600    FW/FX/FY/FK1/FK2          98-02

SV 650      X/SX/Y/XY/K1/K2/SK1/SK2    99-02

GSX 750    FK/FL/FM/FN/FP/FR/FS/FT/FV    89-97

GSX 750    FW/FX/FY/FK1/FK2          98-02

all of those use the same kind of front discs MD3003 LS and RS according to EBC, thanks for the catalog Goose!

Btw, it's a bit surprising the B6's use the same too... quite hefty brakes for a 400, it would seem!

Could you give me some models on which they were standard? Like B12?

nothing on ebay specifically mentions a gsxr1100

those busa ones are the same as srad and tlr.
the 4 pot ones from the older 750 1100 work as do rgv 250 and others im sure , Doesnt the bandit 1200 have 6 piston front breaks? or is that something they put on to?

ah yes about rgv250 calipers.. i'm a little bit puzzled, i found rgv discs and calipers on ebay, but i'm not sure if they fit.
in the ebc list i found several types some use the 'good' ones but other don't. Bad thing is, i don't know which category vj22 fits in :-(

the discs

Hello Alex. Yes these would make a great mod on any with the 2 puck calipers. I'm pretty sure they bolt rite on the 1G B12? The spread is 3.5" or a 32nd 16th more 3 9/16" ? Old calipers and older eyes these days.  Looking at my two pics of bandit and busa the mount holes look to be the same between the two. :motorsmile:

Here is a big pic you could use if you need any other of my to the MM measurements!! :duh: If you want i could take it all apart and send em to ya to try!!! :shock:
You see the stuff on ebay? Looked at the kawi 1400 the other day! All there B parts are so compact!! Wonder if they don't last as long or are made of better stuff??

The 2G B12 has 6-piston (Tokico) front brakes. Never had any breaks on mine though.  :wink:
These are the same as the Busa, etc.
Several Kawasaki models use these too - like the ZRX, ZX-9, etc.

The 1G B12 has 4-piston Nissin calipers. The fork mouting is the same as the 2G though, so you can upgrade a 1G to 2G brakes. (Just be sure to use the Tokico banjo bolts in the calipers, the Nissin bolts have a different pitch.)

The 3G has 4-piston Tokicos, don't know if they interchange though since we haven't had anyone here that's taken possession of one yet.
