Can I run an O-ring 520 chain on my 350X without any issues? Overall width will be slightly wider than a standard chain and I want to know I won't have issues with my chain guides or sprocket guard on the engine.

Thanks!!

That was how it was equipped from Honda, so yes.

Excellent.

I couldn't find anything that defined it- 520 90L is all I found...

I just looked at my old 350X brochure, and it says, sealed O-ring chain, under the driveline section.

I didn’t think to look on the brochure… I was looking in the parts fiche.

I’ve run them on mine with no problem. Although I do prefer the standard chain and eventually went back to it.
