Ok if one was going to buy a Motolanna for a 78 400 which one??Welded or machined?Or does it matter machined looks better but dont want shock problems thanx

85RZwade

For my 350 frame, I chose the welded because I liked the look better. Just personal preference.

I bought the Motolanna one and the one from Webike because of the same reasons as 85RZwade. Optics.
We use them in race bikes so weight advantage is another point.
I don't see how the welded shock mounts are a disadvantage against the machined ones.

On a slightly different note: when I placed my order a few days ago, the standard turnaround time was stated as 2-8 weeks PLUS possible additional delays due to Covid. Got an email this morning that it has shipped!  :cheerleader: :whoop: :celebrate:

Had the same experience last fall. The delivery time was much shorter as announced

Has anyone gotten the motolana swingarm and installed it on a RD400 yet? Anyone have any pics or info on the install ?
Thanks

Bump for curiosity on the Motolanna arm for an RD350. :)

85RZwade

RD pivot bushing slid right into the bearings supplied in the Motolanna. The 'arm is narrower at the pivot than the RD piece, so I made two spacers, I think they ended up at 7.3mm each. Done   :gentleman:

How did everything line up? Stock chain length etc? Shock mount?

85RZwade

Shock mounts are right on. Chain length and alignment are going to be different for me than most, or maybe anybody else, as I'm using the TDR rear wheel I got from Jim. That fitment has to wait until I get a sprocket carrier (Hey Evan, found that sprocket carrier?). At present, the TDR wheel is soaking it's nipples in penetrating oil to ease disassembly prior to accepting the YZ490 rim I bought for it.
I'd try the RD wheel in there for educational purposes, but the hub lives in Canada now with Uncle Rodney (at least I think he still has it).

Ok, well, I am sticking with the stock swingarm for now, but am definitely considering the motolanna in the future. It's the cheapest option that should look pretty good considering the stockish look of my bike.

i'll definitely be getting a motolana arm for the 72 r5 at some point because it certainly doesn't need it. But, it needs it.
