Most unattainable Bling is now mine..........Carbon Swing Arm

[cyrus buelton]

2004 S4r.

Sorry for the shitty pictures, I took my wife's Nikon D60 with a nice new 55-200mm lens, but come to find out, my dumbass didn't put a SD card in it, so I had to use my Bold.

Here is the swing arm in stock form:





Now I just purchased this little beauty from Chris@cyclecat. Brand new, never mounted.





This is a Dymag Carbon Fiber Swingarm. From what Chris told me, Dymag made between 20-25 of these for street bikes. He says this is the last one that is not mounted on a bike and has no idea how many are still in existence. He got this from Alfred at On-Cycles.

Now, there was a story a while back about one of these and it came apart on the track. From what Chris told me, the guy (or whoever he bought it from) tried to convert a street version into the race version. Apparently the individual removed that metal "ring" in the hub portion. Well, the make the beast with two backser came apart and hopefully the guy wasn't hurt too bad.

This thing is bad ass and pretty rare. Almost makes me want to keep it above my fireplace and not mount on my bike!!! I am really not a bling person, but had some good investments come due, Chris gave me a good price, so what the hell?

This is longer than stock, so a friend was telling me I need a longer rear spring as my stock one could make the beast with two backs up handling and lead to instability and a potentially dangerous situation. Anyone have thoughts on this? If so, where do I procure a new spring?


Also, I will be selling my stock swing arm once I get this installed in the next few days. It has 7k miles on it and appears to be in perfect condition. It will only be the swingarm, none of the other parts or anything as they are going on the new one. If interested, PM me now. I will post in the appropriate forum once I have it back and clean it up (not that it is dirty, but just general road grime and won't sell it that way just because, well.......I won't)

I hate you.

I do not appreciate this kind of language in this setting.  










J/K.  Looks Awesome!  I will be dreaming about it tonight in my sleep!

Did you measure your cases yet, that swing arm is intended for a narrow case (SBK).

[junior varsity]

the length isn't on the shock mount side, its in the middle and realized on the wheel end. Your wheel base is longer, giving you a more stable feeling, but I don't think anything changes in the distance between the OEM mount location and this one. You'll want to measure fo'sho'. I don't think there's any change needed to the shock, besides maybe making sure sag and everything is 'right'.

[Speeddog]

That looks like an SBK-style swingarm.

The shock/pushrod mount is quite high in comparison to the Monster, and IIRC the lateral positioning is different as well.

I suspect you'll have to do some shock/rocker/rocker mount/pushrod mods to get it to work.

Congrats, and looking forward to better pics!

He'll also need a Corse (Dan Kyle) style rear link to make it work properly.

This is why I am having Chris install it for me :-)


He says it is a direct fit. I'll have to talk to him about this.

[Speeddog]

Oh yeah, your S4R exhaust won't work either. 

[Raux]

sounds like it won't fit for a lot of reasons  ... pm me when you want to sell 

[junior varsity]

Nah! Just a little custom exhaust work and suspension linkage and he's on the road!

[MotoCreations]

I have one on a customer 998R here in the shop -- simply beautiful artwork they are!  (I wish I had one myself)

As for putting on a S4R?  It's not a 100% bolt-on setup as soon will be discovered.  

Also you will need to do a custom rear header as nothing will fit it that exists.  Shock and shock linkage problems will prevent the use of the SBK rear header and the rear header needs to go SBK outside routed -vs- S4R through-swingarm mounted.  And then you need to decide how you will do cans/routing configuration when finished.  Thus why I always make a custom exhaust for these swaps.

[cyrus buelton]

You guys are correct.

Calovini is going to do some research for me


Moto - let me PM you

[cyrus buelton]

update: Just spoke to Chris who knows a guy by his house that does custom exhaust, fabrication, etc.

We should be good to go 

Not like I can ride anyway this time of year.
