RZ/RD 350 & Misc. 2-Stroke Tech BBS

Does anyone sell a AL swingarm?

Roger@ Wicked Motorsports does one for the RZ.
You can also get a Metamatex from the UK.

Thanks should have been more specific. I am looking for one for a RD350. I will checkout the ones you posted.

It's simple to make a case for why you DON'T want an aluminum swingarm, steel is better.
A 4130 swingarm is lighter, stronger and returns to shape faster than aluminum.

Cox Custom Fabrication is my "go to" guy for all things frame related

Thanks for the info. I am not racing. Looking for more for the aesthetics of a aluminum swingarm.

See if this guy makes one for your bike, he did one for my 84 RZ350. He dose great work!
His name is Ken Brumm, email- k3brmm@sbcglobal.net

That's still not real specific. RD350 could mean Aircooled, it could mean first of watercooled, or in Europe it could mean YPVS, still called RD350 there.

Motolanna sells a couple of arms for the SR500 that just need a spacer on each side of the pivot to fit the air-cooled RD350.

Wow, they look like quality part esp bare. And cheap!

I am familiar with Motolana swingarm I put one on my SR500

I recently talked to Ken and he said he has some more swingarms for sale but he is no longer building them, when there gone that's it!

aha, so that's why all modern race bikes use steel swing-arms.

oh no, wait ... it's the other way round ?

I double checked my recent e-mail conversation with Ken Brumm and this is what I have k3brumm@sbcglobal.net
