Should I do the 520 conversion on my f4i?

Will it really make a noticeable difference on a 600 that already has a 525 chain?

Probably only if it is a dedicated track bike - and even then, I'm not convinced it would be noticeable for 97.25% of the riders.

On the street, you'll notice a dramatically shorter life, possibly increased adjustment intervals.

Yeah, that's what I thought. I can't imagine there would be that much difference between a 525 and a 520. I'm going to track it but not enough to warrant the reduced life.

If you changed the sprocket sizing, sure!

Right now it's +3 on the rear I think.

What reduced life?

Would you go up a couple teeth in the rear or down 1 in the front LDH? I would assume more wear with a smaller front sprocket because of the tighter angle, I'm pretty sure the current set up is plus 2 or 3 in the rear.

The 520 sets are also a little cheaper so even if it's only a marginal difference if there is no reduced life I'll do it.

Even with an aluminum sprocket you should be able to get a minimum of 10,000 miles out of it with basic chain maintenance. I had 16,000+ track only miles on my 1000RR before I finally swapped it out and I know others whom have gotten 20,000+ miles out of 520 kits. All depends on how well you take care of your stuff. Proper chain slack is critical for longevity followed closely by keeping the chain clean & lubed.

The actual choice of sprocket sizes is entirely up to you and your needs.

You also tend to buy the best of the best, many do not.

A lighter chain will wear out faster than a heavier one, it's just not as beefy - and it will require more frequent adjustments.

Common sense

Unless:
1) You buy the best of the best
2) Your motorcycle does not make enough power
3) Your motorcycle makes plenty of power and Steve is FOS
4) You have more posts than miles actually ridden

I did the 520 swap from 530 on my fz6 recently, after 3 years I noticed the difference from the 530.

That's cool.

How many miles?

I've not been able to ride for a couple three days, feeling the need.....

I had 26k on the stock 530 chain, just over 1700 on the 520 and loving it.

What he said. Why? In theory, 520 has less sprocket tooth and chain roller area to distribute the load over hence greater potential for wear. For longevity, tensile strength is king. Many manufacturers' 520 chains carry substantially lower tensile strength ratings than their 530 counterparts. Less sprocket/roller area = heat & wear, less tensile strength = stretch, in theory of course. Now, can somebody tell me the the advantages of 520 on a street bike?

You are wrong. I only sell 2 chains in 520. The ERV3 and the ZVM-X. Both will outlast OEM 530 chains with the same care and upkeep. The ERV3 chain and sprocket kit saves 3-4 lbs of rotational mass over the OEM 530 kit. We've been using these ERV3 chains on 1000cc bikes both street and track for well over a decade with thousands of very happy customers including myself. I won't sell it, if I won't personally use it. Additionally we are also using them on our 205rwhp BMW racebikes. Zero problems...


The zvm-x chain is rated even higher than the erv3 and only weighs .3 of a lb more on my scale. Damn impressive quality.
