Hallo everyone!

The chain on my Dart Is a bit rusty, more than 20 years of non working produced a lot of rust

I Will change for a new One

Please can you all confirm it Is a 520 type chain?
Or something different?

Please let me know
Thanks

Yes, it’s a 520 chain.

I think 114 links but don’t quote me on that!

Recently I’ve been using DID 520 ERVT chains which are narrow x ring chains and have a pretty high tensile strength.

Assuming you are replacing the sprockets too, make sure you buy a 520 front sprocket as both 520 and 530 sizes are available for morini 350s. Mdina italia do stock them:

Thanks for the reply tom!

I'll buy only the chain because the originale One Is a Little rusty, the bike has only 3000km so sprockets Will be almost new i think

I Will change also both the chain sliders, here in Italy are selling some good quality remanifactured parts only for 30 euros
