Hi guy's!! just need some advice. Does anyone know whats the advantage of going to a 530 size chain and sprockets? and if there is any! is there anything i need to know? i have put many chain and sprockets on bikes but do you need to run a special spacer on the front sprocket or straight on as normal? etc etc

None that I can think of, a good 525 chain is just as strong as a 530, the 525 is a little lighter and absorbs less power than a 530,

you will also have less clearance between the chain and tyre and possibly other parts along the chain run and around the front sprocket with a 530,

So no I cant see any reason to convert to a 530

A few people have gone the other way and put 520 chains on instead.

I figured this was a mistype. 530!!!
Jesus! I dropped over 2 kilos going from the stock 525 set up to 520 with aluminium rear sprocket. That is over 2 kilos of rotating , unsprung mass! Why would anyone up-size the chain?
The way I understand it is that mfg. use the larger 525 just to decrease the likelihood of a chain break on a street bike.
GoGo and I ran 520 on our race bikes. I did over one whole race season on the same chain and sprockets. I seriously doubt anyone hammers their chains harder than we did.
Maybe the same but not likely harder.

IMO, everyone should do the 520 conversion just as quickly as the switch out that miserable, heavy ass, exhaust under the seat. Weight is bad, but weight in bad locations is terrible.

Until it snaps

Talk about tunnel vision!

You know, I never thought about how I went over my bike thoroughly each weekend. Before and after!!
I guess I forgot about folks who ride on the street and hardly give maintenance a thought.

My days on the road always started out with a good "walk around", just like I did on my VWs and airplanes.
I am not into wrenching but I am a hell of a lot less interested in mechanical failure.

I am happy you guys pointed my narrow mindedness out. I dig it when I get caught with my foot in my mouth. Doesn't happen very often so it is always a nice cold slap in the face.

No problem, its easy to become focused on your own little world and to forget we are all quite different in experience, knowledge and abilities,

too much focus on track riding IMO, some seem to think its the ultimate and what works on a track is the dogs danglies, wrong http://www.didchain.com/chainSpecs.html

I posted before about sidewinder sprockets/Krause engineering. Wonder if anyone ever bought one. Big warranties on them, I think.
Looking for link now.....

Looks like Vortex are supplying 520 front sprockets now...finally!

I still swear by PMP sprockets for the rear. They wear much better than any other 520 aluminium sprocket I've used. They now have specs for the ZX6 sprockets for the Carrozzeria wheels for an SD application. Ask them for the Lowrance spec. $56 USD for a 38T 520 anodised black.

They make them to fit standard SD wheels as well.
