Drive Chain Life Span?

630 is the "bigger". What it is is longer pitch between rollers and the same width as a 530. Stay 630 if that's what came with the bike or stay 530 if that's what came on it is my recomendation which is generally disputed here

That's what confused me because I see everybody selling shims to move the front sprocket away to keep the wider 630 chain from dragging on the engine case? Even Z1 sells them.

That's ok, every 630 chain I have measured has been wider than a 530 chain.

I have no idea what the spec says regarding width, I just know what the actual dimensions are.
