The soon-to-be-wife was asking me what I wanted for Christmas and I thought this Metmachex SA would fit the bill nicely.

Are these as beautiful in person as they look in the photos? This piece is pure bike porn.

Are they a direct bolt-in? Do I need other parts needed?

I’ve never actually swapped a SA. Is this doable at home?

Would you go for brushed aluminum look or mirror polish?

Thanks.

I'd go with none of the above.

After looking over the weight differences between the mega-reliable and nicely stiff stock steel unit and the aluminum offerings, it just seems to me that far better spent money could be used to go with several other upgrades rather than just one aluminum swinger.

Stripped down weights:

900SS steel - 11.00
Metamachex - 9.45
1000 aluminum - 8.91
900SS aluminum - 7.75

The unsprung weight savings isn't enough to justify the cost from where I stand, unless you're angling towards building a full-on track/race bike (even then an aluminum swingarm isn't truly "necessary"). And let's remember that while the static weight difference between the Metamachex and the stock steel unit may be 1.55 pounds, no where near that much is actually unsprung. The "heavy end" of the swingarm is actually sprung weight (the pivot point end).

If you want to spend a chunk, maybe look into a rear shock upgrade (pick your poison).

Buuuut .... there's the bling factor of the pretty/shiney/bragging-rights swinger! If bling is your thing, then I totally see your point! I'm not totally sure but you may have to change the rear brake setup along with the swingarm (to the fully floating design). I may be wrong about that though.

~Yes~ ... a swingarm swap is something easily done at home, as long as you have a fairly well equipped collection of tools. You'll need a means of standing the bike up without the rear wheel and swingarm attached as well.

Thanks for the reply! I’m already running an Ohlins rear shock, so this change would be all about ‘bling’. Although CF wheels always looked good to me. ;)

This bike will never see a track. I didn’t realize the stock SA is lighter. I have no idea of mine is cracked, but the bike (1992) only has 5200 miles on it, and had never been ridden that hard.

I personally prefer the brushed look as polished will always dull. These are beautifully made but the price!!
I picked up a 1000SS DS swingarm, hard to find but much cheaper than the Metmachex.

You have a decent wife BTW; I have to hide any expenditure on my bike as she has a stupid philosophy that any and all money should be spent on the house, food, her cosmetics and hair care snake oil, and bills. lol.

Lol! I actually started out looking for the1000DS swingarm but the only one i found was in Japan! yikes!

There was also one on eBay (Japan) from deLIGHT Brothers Motorcyles but I did a Google search on that company and came up blank. I only stumbled on the Metamachex from another user’s build thread. I reached out to them this morning and they said they could build me one.

DeLight are a Japanese manufacturer, apparently good quality. But that one on ebay is expensive as it is used.

Yes they absolutely are Racerboy. And then some my friend. I bought one for my 900SS 4 years ago and you're correct they're pure motorcycle porn. Click on the link below and pan down the page to post 198 to see my pics.

Are they a direct bolt-in?
Yep,according to Metmachex they're designed to be a straight swap.

Do I need other parts needed?
Depends. Might need an extra swingarm shim or two to get the correct side to side freeplay.

I’ve never actually swapped a SA. Is this doable at home?
Yep,as long as you have a way to support the back of the bike while you're swapping out the swingarm. Some guys block the engine up from the underside to raise the rear of the bike,some guys support the bike with straps beneath a step ladder. There's all kinds of ways that you can do this.

Would you go for brushed aluminum look or mirror polish?
I actually prefer the mirror polish myself but I'm thinking about powdercoating mine.

i had an ss with one in last week. one thing i noticed is that the hugger was extremely high at the back, and looked quite odd. not sure what you'd be able to do about it.

Have a look at that pic. I posted a few comments up and you'll see what I did to support the bike; two M10 high tensile bolts out the side of crankcase supported by an axle stand either side. Cheap and easy and hasn't moved in a week, but will today as extra shims have arrived in the post.

Here are the pics they sent me today.
:surprise:
Gobsmacked. That's a work of art there. I am just about to install my repaired OEM swing arm in a couple of days or so. Well....I was, at any rate. It's been apart for the better part of a year....and now I can't find what I did with the shims! Thanks for posting that swing arm porn............sean

Congratulations. You won't regret it Racerboy. :yeah:

Contrary to what Rex said (and no offense intended here Rex) these Metmachex swingarms are not simply just bling items. It's true they are pretty and shiny but they're also functional as well.
When I bought mine they were advertised as being stronger and more torsionally rigid than the stock aluminum swingarm.

These Metmachex swingarms are equipped with an eccentric axle adjuster that allows you to make quick easy chain slack adjustments. The axle bolt has a woodruff key installed on the hex head end of the bolt and a flat milled surface on the threaded end of the bolt. See the pic below.

That woodruff key and flat milled surface lock into the black outer eccentric adjuster plates on either side of the swingarm. This allows the adjuster plates to move simultaneously when making the chain slack adjustment.

Simply loosen the axle nut,loosen the four allen bolts on the black eccentric adjuster plates,turn the hex head on the axle bolt to make your chain slack adjustment,tighten and torque the axle nut and four allen bolts and off you go. No more guessing if you've got the rear wheel aligned properly or not.

You guys are tempting me with that swingarm lol--but I would probably put it in the glass bead cabinet to give it more of a stock satin finish instead of being polished, being that I like the more stock look. But damn I am tempted

Beautiful bike! What do you think about a black SA with a white frame?

No offense taken. :wink2: Respect, yo!

Well and good, but to put my comments in proper context, they're not as strong/rigid as the stock steel swingarms, which is what my comments about "stronger/rigidity" were aimed at. And the Metmachex aluminum swinger is only 1.55 pounds lighter than the stock steel units. Most of that weight is carried at the pivot end, so it's not like there is a savings of 1.55 pounds in unsprung weight. The unsprung weight reduction is a certain percentage of that.

Those were my points. Opinions were asked for, so I provided as much data as I had on the issue. From my point of view the advantages don't justify the cost. But that doesn't mean I think other folks' desires for one of the Metmachex units is material only.

Everyone has their own ideas of what ~good~ is. And I'm fine with that!
