Similar to the late TZ fender but without holes.

My favorite version:

BIN/BO $25k

Not mine. Not likely to be mine but I wish...

Apparently has been street registered? Not sure.

Chuck did a topic about rod bearings and using Suzuki RM125 small end bearings a while back. Economy Cycle had some at one point I think.

 Someone just needs to go to China with a 400 crank and commission a lot of them. A factory drawing set would be helpful too. They are surprisingly accommodating and business is down. The unit price is lower with economy of scale.

 The question is, how many would people buy one right away to recoup the investment? Setup costs are much lower than you'd expect and they have low profit expectations compared to the West. You really have to go over there to get the best deal. But then they'll never stop calling you...

I have a later version of a TZ350 fender on my RD350. It's a fiberglass replica. Probably Airtech?
This one:

It does fit an RD350 even though the fork spacing is different. Installation was super easy.

There are a few that would probably fit there:

Airtech is now owned/manufactured by GP Cycleworks.

Nevermind the rust stains and water damage. It was only underwater for 5 hours 3 years ago.

If you want to sell a piece like this wouldn't you take 5 minutes with a rag and some WD40? ...Or does that remove the "patina." Maybe that's why it's $7500 with no title.

Definitely better than oil dripping from your chest pocket.

...shifting with your right foot!

Here's some real ones for a 350:

$1499 in Singapore

eBay. In UK. Roughly $750

Says they are billet but they are definitely cast to my eye. Brand listed as LC Engineering. Search turns up nothing under that name.

Not mine. I know people are looking for these. Not a bad price assuming that it's for a pair.

Mark, you can move to the eBay section if you need/want to.

Mark,
  Did you put the rubber vibration dampers back on or just bolt it solid?

Probably a direct swap...

I'd say this is the prototype. Hopefully the production model (though limited) is a bit more finished looking.

 If typical they are looking to sell them all first to get the money to actually build 24. Do they even have tooling? It's got to be $150k+. ~$3.6m total. Pay now. Ride later. Unless we go out of business before you get yours. It's a one-off custom at this point. Selling a dream...

Yeah, I wondered about the mono shock mount part. The RZ has dogbones.

I have a 120/80 rear tire on now and I don't care to go any wider. I'd just like to have less than a RCH clearance between the tire and swingarm. I ground the gussets and used an extra link in the chain but the adjusters are all the way out. About 3.5-4mm clearance on either side. 2.75" rim.

The pic Uwe posted does not look like an RZ. Unless the axle tabs were cut off. Hard to tell since it's so nicely finished. The one I posted as an LC looks more like it...  I think I found the answer (photo).

I guess you always have to take what AI says with a grain of salt. Same with internet searches and things sellers post. My discussion with AI had a number of flaws that I recognized. Having never spent much time with either RZ or LC I didn't know the difference. I wasn't really aware they were such different motorcycles. Beyond the YPVS system, rear drum and styling. Why did they go back to a drum brake anyway?
 I can get an RZ swingarm for $130. Cheapest aftermarket is ~$850. Steel is fine. I can save the most weight by losing 40 lbs. Seems there are a lot of improperly done arms out there bases on Mark's comment about shock placement.
 There doesn't seem to be a definitive answer as to what the best swap candidate is. We've had various threads without a conclusion.
 I really don't want an RD400+1", which seems to be the most common choice available as far as Motolanna and SR aftermarket pieces. I don't want to change to a rear disc so I'd have to modify a 400 arm anyway for the 350 brake stay. Which I've also strongly considered. That is more of a "sideways" move. Like everyone else, I'd love to find a DG swingarm for a 350 for a reasonable price.
 Thanks for the input guys. The more ideas the better.

 Stresa posted a photo in this thread of a swingarm captioned as a RD350 YPVS a while back.
https://www.2strokeworld.net/forum/index.php?topic=4031.

 It looks like a RD350LC arm. Doing some rabbit-hole research, I see that the watercooled to aircooled swingarm swap is not uncommon. Requires some cutting and welding to convert to twin shocks and clean up/patch some unnecessary things.

 I didn't realize that the LC and RZ swingarms were so different having never compared them side by side. Which is a better swap candidate? Main goal is additional tire clearance. Anyone have experience with the subject?

Thanks!
