I would use all steel sprockets unless this is a track bike. Also, you may want to think about using the stock size chain for better life. Try giving Patrick a call... his prices are better then the internets on alot of stuff and you save on shipping. Plus, if you are not able to do this work yourself you will probably get a better deal on install if you purchase it from the same person doing the install.

With today's top-of-the-line chains you will have just as good fo chain life w/ a 520. The key to chain life is proper maintenance. Keep it clean, lubed, and well adjusted and you will find that it will last. Especially on an SV650.

I have a 520 conversion on my RC51 and it is lasting just as long as my 530. 10,000 miles and counting.

Question, what is the gain in switching from 530 to 520? Just so you can change sprockets, weight savings, or???

lighter weight. Allows your motor to spin up fatser and w/ less strain (ie- increase in power)

FWIW, Moto GP guys run 520s on their powerful bikes...

I was considering it, but I don't know if I want to just yet. 18,000 miles and I noticed there is some wear on my sprockets... so either way I'm getting a new chain and sprockets... I just don't know what size yet.

in my eye's its not worth the extra money,and you wont notice the diffrence enough to make it worth changing to it if your chain/sprockets are in good condition

That's what I was thinking, I know on the RC a lot of people change because they are geared so high, not much fun for a street bike.

Anyway, didn't mean to up this mans thread.

Nah its all good...everyone has good opinions to this...
I talked to Pat up at motorcycle unlimited and he said its really not worth it..he explained that they only last for about 6 to 8000 miles till they get worn out and u dont really feel any hp gains...he did say just change the front sprocket down a tooth or so...or up i forgot..well i am glad i posted this b4 i wasted my money on ebay...thanks!!!!!!!

I have been running a 520 conversion on my F4i for awhile now, DID 520 ERV-3, AFAM drilled front stock size and a Stealth +2 rear. The rear sprocket is getting chewed up, maybe a bad heat treat but the chain is still good and as for the front sprocket I haven't checked it yet but maybe it's ok. I am hoping that it lasts another 3k before I replace it, going back to a 525 running a DID VM. I will most likely go back to stock gearing as gas is pricey and am noticing the rear tire doesn't last too long. (but OH the acceleration)

If you want quicker acceleration change out the sprocket teeth by going up more in the rear or down in the front. If you want to lose weight goto aftermarket wheels, Wave Rotors, or diet.

you dont go to the 520 to lose weight you do it for less rotating mass, i realize the diet part was a joke but just had to point out that it wouldnt help in the same way the other stuff you listed would
