chain size

[matt2778]

I was looking for a new chain and sprocket combo and was wondering if a 520 would hold up well on a gixxer750. What would the life of the chain be?

It would be fine, mileage dependant on maintenance and quality of kit.

go down 1 tooth in the front while you're at it
that 750 you're ridin' could use a little help
