what does converting from a #525 chain to a #520 chain do for your bike?

i already know how a sprocket change works but i dunno how this one works.

it does absolutely nothing for a street bike other than give you a chain that doesn't last as long.

on a race bike the #520 conversion is done to eek every little bit of performance out of the bike since the #520 chain is lighter.

It looks like Verm will be changing chains, hahahaha.

thanks, is that all it does? make it lighter, that's it?

im already light enough, so losing weight on the bike isn't top priority... our power-weight ratio is already pretty good.

Yeah, if I wanted to lose a little weight for performance, I would put my aZZ on a diet.

Nothing...my ex250 comes stock with a 520 chain.

What? they dont have an aluminum chain out yet?

Titianium would be the way to go, get one custom made, thats the ticket. I bet no one else has one.

This does absolutely nothing. In some cases this can be detrimental... but I haven't taken the time or money to check on this (plus, I can't go any smaller = 520 as it is)

If it works fine then leave it, If you want more performance then get a lighter sprocket set and an X-ring chain for less drag, but that's nitpicking.

aside from reducing rotating mass? lots of jack and "poo poo".

plus #520 chains are rather short lived on anything bigger than a 600 (heck they are even short lived on a 600).

I run a #530 on my bandit and dont see a need for a lighter chain.
