Title: Shocks (Sorry!)
Post by: HD on January 27, 2012, 05:56:22 PM
Hey,

Done a little bit of reading around and nothing is for definite. I can't really find any shocks that are a definite fit and that don't change the rear too much.

The bike had a Hagon shock on it before I got it and it has gone (rebuilding the bike) so sent many emails to Hagon and a photo and it turned out they can't rebuild it because it is so old they no longer have parts?!!

So I need something to bolt straight in for either just the MOT but preferably something permanent. I am aware that the early GSXR 750's go in but no info about tail height and they are very scarce down here!

I am a tall rider (6'1" and rugby like figure of ~18st) and the rear is already raised so don't want to put it up much higher really as I don't fancy fannying around with the forks. I need to change the seals and oil down there soon though so could always put heavier fork oil in.

There is some info on Bandit 1200 shocks but I'm not sure on what it really means. I need something that will bolt straight in with minimal change to the right height. There are some for sale this way but not sure if they will go straight in without drastic changes to handling.

Thanks! :up:

I swapped mine with a 91 gsxr 750 shock and they were nearly identical in length.

The only difference in ride height was caused by the new shock being stiffer and not sagging like the old one.

How about a '98? http://www.ebay.co.uk/itm/Suzuki-GSXR750-suspension-mono-shock-monoshock-1988-/110813704846?pt=UK_Motorcycle_Parts&hash=item19cd02f28e#ht_500wt_1202 (http://www.ebay.co.uk/itm/Suzuki-GSXR750-suspension-mono-shock-monoshock-1988-/110813704846?pt=UK_Motorcycle_Parts&hash=item19cd02f28e#ht_500wt_1202)

Looks like it is missing spacers but I have them from the Hagon. Such a waste of a shock though :(

Exactly what I noticed with the '91 shock. Much more adjustable as well with the compression and rebound damping. Didn't have to modify anything - direct bolt on part, just gotta mount the remote reservoir.
The '88 shock looks similar enough but you can't really tell from the picture. Even the '92 gsxr shock has to be ground down to fit just because in that year they went from a rounded top mount to hex shaped and so it doesn't line up on the bandit... I suggest searching for the '91 shock if you want improved suspension, a direct no bs bolt-on, and maintain the tail height.

93, 94, 95 gsxr 750 are a direct fit.

  I have a extra shock from a GSX-R 1100w,but I don't remember the year off hand.(early 90s) It took a little grinding to fit it and raised the rear ride hieght 1 1/2 ". I have a Works Performance on now,Id let the GSX-R shock go cheap,but it would cost too much in shipping to get it to you.

That's a pain! Would be looking at keeping the ride height really but an inch isn't that much and I am flat footed on both sides atm.

Cheers guys!

I simply purchased a new shock for my '00 model from Suzuki - bolted right in and works as it should - very happy

I put in a shock from a 2006 GSXR 600.  Had to move the coolant tank because of integral reservoir but fits perfectly other than that.  Fully adjustable.  Picked up 2 off eBay from different sellers at $20 each.

I bought one of the old ones with the remote reservoir but it was worn out and had leaking seals.  The newer ones are much better... and newer.

Pretty much settled on a bandit 1200 mk1 shock. It is 300mm so 5mm less but I already have longer dogbones on the bike so should be pretty much standard size. I can still look around for a 91 gsxr 750 shock and always buy that and sell the bandit one or just make shorter dogbones.

Thanks gents!

So wouldn't the bike become unbalanced without also replacing the front forks?
Title: Re: Shocks (Sorry!)
Post by: canyonbreeze on February 03, 2012, 02:35:19 PM
I replaced the front springs with 1.0 straight weight ones and 15W fork oil.  Seems very balanced, much better than stock.  I have cheap gold rebound valves I'll put in at some future date.

Hm okai.. whats the size (length?) of the rear shock? (I assume from hole to hole)?
Oh and what would be a good place for the external reservoir?

Look right down to the end of the sticky.

Based on the chart in this thread, the 91 GSXR 750 length is 312 mm, and based on the photo above, the Bandit 400 shock must be pretty similar.

But above he says "300 so 5mm shorter". Shouldn't it be 305mm?
And just to clarify. The 92' gsxr750 is different from the 91 and 93, 94, 95?

Sorry Squishy, I'm an EX Bandit 600 guy, so I have no idea what length a stock Bandit 400 shock is. Maybe one of the 400 guys has a spare shock they can measure.

As for GSXR 750 shocks, again based on the chart I referenced, the 88-91 as well as the 92-95 shocks are all 312 mm, eye to eye. I ASSUME the 88-91 have a remote, hose mounted reservoir, and that the 92-95 likely have the reservoir integrated into the shock body, which can make it harder to mount, but I DON'T actually know.

Anyone know whether the GSX750F '91 shock is the same as the GSXR750 '91 talked about in this topic?
Thanks

Lastly, the picture posted in the 1st page.. is it a 1991 or 1992 shock, because here the poster says its a 1992 shock:

Also: from here

they say b4 stock is 305mm.

I'm not exactly sure. I'd say the older post that says 1992 is probably correct. It was closer to the time I bought it.  But who knows, I bought it from eBay and never saw the original bike it came from. The original ad said 90, 91, 92 gsxr 750 shock. It probably said 1992 in description but I can't access it. It fit and was an easy install. I have so many parts from so many years I can't keep it all straight anymore.

Okai, I got myself a '95 GSX-R750 W. Took my longer than expected because couldn't reach the bolts properly and the cooling reservoir was in the way of the hose.

I've got some questions:
1) Is it possible to turn around the shock 180% degrees? So that the hose is on the other side?
2) Does the external reservoir need re-filling?
3) Where did you guys mount the reservoir?

Thanks

When I put a 2006 GSXR600 shock on mine I bought a SS tube style overflow container and bolted/zip-tied it under the passenger seat area(not the passenger seat itself, but the bike).

I obviously ran new lines to it....I've been running run with no clearance issues.

It was difficult to the get shock itself in and I don't believe there was enough clearance to rotate it at all. I had to use 2mm washers to space the dog bones out a little and mill a little off of the aluminum casting that ties everything together.

Make sure you fill your radiator really well and just put a bit into the new overflow reservoir...it shouldn't need much.


Edit: I just realized the reservoir you're referring to is from a remote reservoir shock...lol....sorry. I suppose if the line is long enough you can run it to the same place. Or you can move the overflow container to where I put mine and place your shock res. in front of the batter housing using the brackets that are already there.....

Some of those shock are nitrogen charged and I wouldn't be disconnecting the remote resevoir if I were you...leave it intact and don't mess with it....if you already have taken it apart/seperated from the main body you'll have to find a shock expert here to tell you what's needed. If it's bad news you might be better off doing like me and finding a low mileage one on e-bay...I only paid $15+$10 shipping for mine.

What do you mean stock reservoir? The b400's stock shock doesn't have a reservoir, that's why I'm asking
Title: Re: Shocks (Sorry!)
Post by: Nickelodeon on June 10, 2012, 05:41:23 PM
It's really my fault for not using the correct terminology.

Let me try again.

I'm going to assume your GSXR750 shock has a remote reservoir, connected by a hydraulic line. My gsxr600 shock has one but it's part of the upper casting and as a result I had no option but to remove and relocate the coolant overflow tank in front of the battery to make room for it.

I was suggesting that if your remote reservoir for your shock doesn't have a long enough line(or is an integral casting like mine) you won't have many options but to do like me and move your coolant overflow tank. Make sense now?
 
I moved the coolant overflow tank under the rear passenger seat, under the rear tray specifically.(using an aftermarket "tube" style I bought off e-bay) I'll snap some pictures next time I have my bike out of the garage if you're still not clear(It's raining right now).

Well I mounted it under my seat, i'm pretty happy with it.
Still wondering about questions 1 and 2 though
