Help!
Advice needed…
95 900SS
Friday I noticed a small patch of oil under the nearside fork leg….
I knew that the stanchions would need replacing or replating soon and this was making the decision for me ahead of its MOT.
Start looking on the internet for seals, bushes, stanchions etc and think about posting in these forums asking if anyone can recommend on hard chrome platers in the UK and any advice on the necessary rebuild….

Also realise I need someway of supporting the bike while the doing this job so order a front head paddock stand…

Any ways… Looking on ebay I find these
Ducati 900 SS FORKS + YOKES handlebar + Risers ( Spares Or Repair) | eBay
sensible..ish price …what can be up with them?

Then I check out the photos and see the corrosion on the outer/upper alloy tubes….
A sense of growing dread and I go back to check mine….nowhere near as bad but unmissable corrosion eating into the alloy tube…

So now a real dilemma.. No point in sorting seals/bushes or stanchions when the uppers also need replacement..

• Has anyone got a set of Showa GD-011 forks for a 95 900SS in good order they would be prepared to sell?
• Anyone with upper tubes they would sell?
• Any suggestions of alternatives, Ducati or otherwise, that would fit with minimal effort? I guess later SS iE are longer and bigger dia so would need new triple clamps and calipers?

Any suggestions at all most welcome.
(looks like I need new front discs too…. Its been sat a while as I work away from home  paying for the neglect now…)

I did not see which forks you have (showa,marrzocci adjustable or not.)

The weak point on the 41mm forks is the chrome pitting or peeling if the new forks are pitted/peeling there is little benefit to buying them. Tardosi (sp) makes replacement tubes for the 41's, not cheap but then you are good.

You might consider a 43mm fork as the chrome has been holding up better and it is a bit stiffer. Yes you would need some more parts to convert but it can be done. Both 41 and 43mm showas have poor springs/valves so keep that in mind if you are doing new tubes.

If you want to keep it original then I would put the new tubes in and valve/spring them, once done you would have very good oem looking forks.

I bought a used set of forks just for the lower legs after I found what a replacement set cost. If that set in the ad had good chrome it's a bargain.

Hi Ducvet

The issue with the ones on ebay isn't the chrome....
I was going to upload a photo however seem to be struggling with that! Have a look at the ad...about fourth photo. I am reasonably confident I can get the stanchions reclaimed with hard chroming but I haven't a clue what to do about heavy corrosion of aluminium extrusions like this..

Hopefully managed the picture

Hi Joe-B

I am guessing Mark is based in the States has he a webshop?

The scary part of buying from the States, when you are in the UK, especially something like forks will be the shipping and then the mahoosive duty Customs will want on it arrival :-(

You may be able to buy new ones. If I've got the correct part (15?) Stein-Dinse in Germany may be able to supply them for around 140 Euro.

Stein-Dinse GmbH Ersatzteillisten

Or try your local Ducati dealer? One of the NZ guys here had the same problem with his forks (uppers), and got new ones for around NZ$300 a side.

There's an outfit in the UK that specialises in restoring and replating fork legs - with a variety of different finishes. Motorcycle Suspension Specialists I Brook Suspension

I have never seen anything like those uppers. That's not normal. They are not something I'd want to use, structurally.

I'd look for a set of early 748 or 916 forks. They have the same caliper spacing as your SS calipers 40mm.

You would need to bore the top yoke to 53mm and use some 0.5mm shim stock on the lower.

Ideally a later SSie or SBK front wheel. but not a must. Bearing/Axel and spacer conversion has been documented often enough here (search for Superbike fork conversion).

You get newer, stiffer forks with a superior damping circuit. If you are patient finding parts on ebay bargins are to had. I found my 748 forks for 75 quid on Ebay.

Or

GASXR750 K1-K3 forks/front-end will slot straight in the yokes. Has a good damping circuit and the Suzie front wheel is ALOT lighter. Also well documented hier.

The problem is always the speedo drive.

You need two speedometer senders -
  1. the shell/spacer portion for the new axle diameter and
  2. replace the inner gearing (both gears) with the inner gears from your SS.

Apparently not as uncommon as I would like to think - the photo above was from the Ebay ad, these ones attached are mine :-(
Talking to a dealer today I understood while not common not as unheard of as you or I would hope. I agree with you I definitely do not want to ride on them.....

Many thanks for this link, I had forgotten about Stein Dinse
Actually part 25 on their drawing, price is good, well better than I expected! I checked with a UK dealer and it was somewhat north of £400 per side...........when I sad that was a little steep he suggested Stein Dinse!!
So all in with shipping about £200 from Stein Dinse and £900 from the UK main dealer. Of course I would still need stanchions, seals and bushes so need to see what the practical options of what if any second hand options are available.

Note that rspete is from the UK. They put a LOT of salt on their roads over the winter... ...it doesn't take much to sit and corrode out alloy (or damn near anything else). And FYI - Combi245 (another Kiwi) had a similar problem with his outers.

I have to wonder if the GSXR uppers would work with Ducati lower legs. If so, they are easier to come by. I even have a decent set lying about from when I stole the internals. They must be very similar, as the guts were almost a drop in swap.

You're welcome. I bought a bunch of stuff off them a while ago, and they were good to deal with (though slow shipping from Germany to NZ). Good luck with it all.

Likewise and for the same reason. Diameters and length are ok, but the Suzuki lowers are bigger diameter (43mm vs Ducati 41). I sort of wondered if the uppers are indeed the same, with the difference in diameters being handled by different ID bushes. Happy to strip out the GSXR ones and measure, but don't have any Ducati ones to hand (other than on the bike of course).
You'd still have problems with differing fork bottoms though.

Give Ian at Rhodes & Track in Northampton a ring Rhodes & Track - About Us, he used to work for Baines & Forza Italia at Silverstone, he will know what will fit & might know where to get them from

I have been mulling this over all week end. (I work away from home during the week so nothing gets done then other than surfing the net and trying to find parts....)
Option 1 Rebuild standard forks.
• Get new uppers
• New bushes and seals
• Get stanchions re- Hard chromed
• New oil
Option 2 Buy standard replacement
• Haven’t found any yet
• Unknown quantity which may need all the above.
Option 3 Fit something more modern
• There is no easy straight swap
• Some are easier than others
• Modify yokes
• New axle
• New bearings/spacers/wheel
• Possible machining of yokes (needing new handlebars)
• Spacing issues with brakes….
So option 1
• Easiest
• Dependent on a lot of factors but cost anywhere between £200 -£400 (providing I don’t source parts from Ducati dealer then the upper limit is £1200- £1300)
• Minimal changes to fit (well none I can think of….)
Option 2
• Somewhat rarer than rocking horse shit
• If found will probably need rebuild….
Option 3
• More fun 
• More hassle 
• No access to a machine shop anymore and with limited facilities..   
• Cost of paying for parts and machining could put this on par with expensive option 1
So I am going for Option 1.
Having got the forks off yesterday I had a good look at the alloy corrosion. It looks a lot worse than it appears, which is bloody awful. Scraped off the worst and was down to bare alloy straight away so will give it a good clean off and thorough inspection over next weekend. If this is only surface and nothing appears to be dangerous then I will probably clean up and reuse the uppers.
Depending of course on how confident I am in them…… Even at Stein Dinse prices the rebuild would add up… UK dealer prices are eyewatering…

So assuming I am going for standard Showa rebuild is there anything that is recommended I do while they are apart?
• Recommendations on where or what to get in the way of seals
• Bushes
• Any suggestions on Springing or re-valving that is beneficial and where to go for parts (this is only really likely to be on if the uppers do not need replacing
• I guess I’m looking for the Best bang for buck mod that people would recommend short of replacing them with Ohlins…..
