Dual Sided Swingarms - Aluminum or Steel

[junior varsity]

99 M900 (partially an S? - adjustable front showa suspenders, alu swingarm, horrible boge sachs rear, non-floating rear brake)

Hope that makes the comparo more wonky.

Just to shake things up even more, my '04 620 caperix has the aluminum swingarm.  It  does not have the 140 mph + top speed some have talked about though, I think that was extra.

Yeah, Capirexes came with aluminum swingarms.  Duck Stew knows almost everything but we can't hold him accountable for all trivia.    Slight thread drift, actually a major one - I've got a kick out of the 140mph Capirex jokes for a long time.  I missed how it all started, evidently somebody named Randall on TOB claimed his would go 140?  Don't know if Randall is still around.

yes, DucK-Stew

my '98 M900 - has alum swingarm & adj forks w/ Sachs shock. is not titled an 'S' but seems to have come w/ S specs.

[junior varsity]

My 99 had the same setup: adj. showa forks, alu swingarm, SS V-stamped heads, BS rear shock.

Things are different now, in regards to the suspension, with penske out rear and the front redone with racetech, but the swingarm is still aluminum, the hoop is now billet, and the heads are still chuggin' along.

hmm, just thinking, would an aluminum swingarm from a 2001 S4 fit a 2007 695? I like the looks of the aluminum arm much better than the steel one.

The rear axle (IIRC) is wider on the AL arm than the steel one, but other than that it should swap onto your 695.

[Raux]

the AL swingarms on the Monsters had the 851 suspension, but the AL swingarms of the SS had a different one, similar to the new 696 right?
was the shockmount off to the side the same as well?    see what i'm thinking?

edit: nevermind. 17mm rear axle, center mounted shock.

[Speeddog]

I suspect an SS swingarm could be modded to fit a 696 without tremendous trouble.

But I've never looked at 'em with that thought in mind, so YMMV.

[brad black]

you could turn an ss one upside down so it looked like a tricolour kit one or the ones that jm (?) in the uk make.

also need to remember that all S4 and all other 2002 onward monsters use the ST based frame with the different rear suspension to the earlier ones.  only STs with an aluminium swingarm were the 4S and 3S.

my 89 851 al swingarm has screw on stand bobbins.  they were welded on very soon after.  plus the 851 and 888 arms all have 4 screw huggers, with the screws going into little welded on tabs horizontally.  later 600/750/900m ones have 3 screws vertically.  not actually sure when they changed, but the 600m appeared in 95 after the 888 was finished so i'm guesing all 95 have the 3 bolt style.

plus the early 851 arms don't have a hole on the rh side to get the lower shock bolt out.  you have to remove the exhaust to get the shock out as the bolt comes out into the opening the exhaust goes through.  it's not much fun with the subframe, coolant res and all.

isn't the al arm actually heavier than the steel one?

i know this is an old thread, but was doing a bit of casual research on swingarms again (i still think the JMC and Metmachex swingarms look great - and are available with bracing) - but I hadn't seen an OEM Ducati 851/888/M900 aluminum swingarm until one popped up on eBay - thing is super cool


Did what reading up I could on it, and it appears it was part of the race kit.

If I could get ahold of the seller, I would pay him to ship it to the US, but my attempts have gone unanswered.

[junior varsity]

The one pictured in the previous post much more closely resembles the aluminum swingarm on my M900, while the 851 KIT swingarm is slightly different, such as where the spools are mounted, and some thicknesses.

[Travman]

Looks pretty cool.  The one in the first picture looks like a regular aluminum swingarm with the underneath bracing added.  The one in the second picture on the 851 looks kind of spindly in comparison. 

Any luck contacting the seller?

[greenmonster]

The one in ebay link looks like original888/early Monster w bracing.


A friend has this Metmachex for sale, never mounted:



PM if you`re interested.
