The magnesium swingarms were slightly longer essentially for better handling of the shock, but the big advantage in my eyes is the weight savings. The stock swing arm is silly heavy. I would be interested in a magnesium replica of the stock swingarm. I believe the stock aluminum swingarms are cast as two pieces and welded together. I have never had a magnesium swingarm in my hands to discern how it is made. Keep us posted on how your deep sump cases workout. Best Wishes Brad.

Reason: additions.
I'm sure there is something about that swingarm that makes it so damn expensive to make, otherwise someone else surely would be doing it. Obviously the demand is there, I mean there are people paying 2500~3500 bucks for used ones.
But damn I wonder if it's just because they are rare. Worth taking a look at anyway.
I know I'd give 1,500~2,000 for one if it was nice. And that's used. Sell a new one for 1,500 and you'd have something.

Maybe Durrani can help, I hear he isn't too busy.
i would need a print, a scanned CAD or the unit to hold here for a week to start. the mag might be tough as it is a bit expensive and i am wondering a small compramise can be done in say all cast alum? the minimal weight gain would offset a huge price drop and better availability
i am eager to get some pics at least so my guy can look at it. i want to contribute some more as well as get some time working with foundry stuff as that really looks like a awesome hobby and his shop blew me away the stuff he had

do you have a stock one to use?
i can have the tooling done to even make the OEM longer then so we skin the cat twice possibly
i am wanting to have my RC30 swinger done out of billet here this winter for a wider cutout and a wee bit longer too but if this guy can sand cast this stuff and make alterations easily for half the dough of the billet it might be worth a shot
OH, doing the RC30 valve covers too but prolly in alum

I've seen stock ones going for $50-60 bucks with a scrape or two....if you need one gotham, metroduc, wounded duc, pretty much anyone who breaks ducs should have one.

i see that for sure
i have asked my guy about the materials and am waiting too hear back
think we can rustle up 6 people for longer cast jobbies?

+1 for above. I believe the current pricing of mag swingarms is based on availability as few were made. Carl Foggarty actually tried a double sided swingarm for weight savings and control of torsional rigidity but it didnt pan out.
Stock swingarms are easily available. I dont have an extra but could source one as listed. The cost of the new swingarm would be the limiting issue for me. Of course it would have to stand up to its intended use. A pretty and light but nonfuctional part is not gonna work here. I would be willing to track test a unit. Consinder the price of used 848 swingarm as a good price point comparason.
This may seem intuitive, but if some non bike oriented is woking on extending a stock swingarm on cad software, remember to stretch it outside the rim/tire diameter. The use of stock suspension connectors and bearings would be excellent as well.
Please do try to get a price estimate. Brad
I would advocate the price of the swingarm needs to include the cost of machining it to make it usable.
Only one on this board I have seen with those skills is Larry.
Machining magnesium presents its one major challenge and that is flammability. Get it wrong and your shop is in flames.
OK, so just because you only know larry means out of damn near 300 millions people in the USA i could not have found somebody who can cast metals properly, you have to be kidding right?
also, FWIW the mag swingarms are not 100% mag they are a alloy
I guess this means you will not be buying a cast swingarm then right

Actualy I dont think Larry Can Cast anything except a V-4.
But once the raw casting is completed the front bearings need to be machined, the rear eccentric, and several other bolt holes need to be drilled and tapped. All to some degree of accuracy off of a casting.
I would assume you would have to sacrifice one to establish where these things are. Either from an original or thru trial an error.
Lots of competent people out there can do it (other than Larry), they all charge though.
I would love a Magnesium Swingarm, don't have the money right now though.

i have a machinest next door who does all this this guys castings. they were machining 10,000$ somehting or anothers today when i was there. this guy has been casting metals for 30 years i am sure a swingarm is not that difficult
i will have to get a final price and i would mostly need cusotmers lined up as i am not going to fot the bill for $1800 swingarms i can't even use without at leats 6 people with money ready

Marc,
Can you get other parts cast as well? I could be interested in some side case covers. I have a spare set that could be used for set-up. How many sets would you need to make it happen?

Thanks,
Dan
case covers would be ace
do they need to be stronger too?
Send me them Dan and i will gladly take them over for a look and price for you and i appreciate the heads up attitude
