1993 900ss swinging arm - will it fit an 800ss

[twpd]

One of my 800's has an alloy swinging arm. The other has a steel item (bloody Ducati!)...I'm after another alloy item for the second bike. Can anyone tell me if a 93 900ss alloy item will fit? It looks remarkably similar.

Cheers!

The early SS uses a 17mm rear spindle, that may have a bearing (pun intended) on things

lol. I'll drop my swinging arm out and will measure the spindle diamter then. Thanks Kev.

No reason why you can't switch to an older wheel setup as I don't think there's much difference.

I'm using an alloy swingarm in the 600SS frame with the 620 engine - a real bitsa!

I'm trying to get the bikes to be exactly the same set up. One came with alloy Marchesinis and the new bike came with 3-spoke jobs plus the steel arm. It would seem that 800ss' with the 5 spoke wheels and alloy arms are rare beasts indeed and alloy arms even rarer again.

The larger section 900SSie arm may be more compatable, if spindle sizes are different then it could mean using earlier wheels, cush drive and brake plate and for racing where you my want to use wets, inters and slicks thats a few other wheels unless you can change the bearings in later wheels IF they do have different spidle size (17mm is very small by todays standards) and the ones in the early SS are a bit of a odd sized bearing

[twpd]

Ahhh....right. OK then Kev..sounds like more trouble than it's worth. I'll go looking for a broken ssie bike then-not that there's many of them either. I wish Ducati would stop dicking around with the spec of bikes like this.


...and thanks for the pointers btw.

Just check your rear spindle size if it 17mm then go with the older arm, if its bigger go with a newer arm, Probably a listing of the wheel bearings somewhere that will give you the ID and therefore the spindle size.

The rear wheel spindle is of the bigger type - just fitted a 5-spoker in and it uses the larger spindle so, I need to find the later arm then. Thanks for the help Kev.
