whats the difference between a 520 chain and a 530 chain i have a 530why didn't they go with a 520 everyone on here has a 520 whats the diffence i also had them put on a vortex spocket down 2 in the back

 

A 520 chain is lighter/thinner/ and the pitch is different (hence the 520). Everyone goes with them because they are in fact notably lighter, the less rotational mass you have, theoretically the quicker it will spin up. The factory doesnt put them on for longevity/strength reason to be sure. They likely wont last as long under high horsepower loads and the liability of one breaking is too much for the factory to want to deal with. They will work on most any moder bike (non turbo/nitrous fed) with good success. If taken care of it'll last for quite some time. I had 15k on my 520 kit on my 99 900RR and it looked brand new. Also aluminum rear sprockets are much lighter and will work fine on any 600cc bike with a 520 kit. A 1000 will work too if you either dont mind changing it more often or running a 530 chain to spread out the forces applied to it.

-2 in the rear? Why on earth would you do that? Do you mean +2? -1 is for the front (generally) and +2 is for the rear. That numerically gears the bike down more (less top end, more grunt) You went the wrong way man.

 

i went 2 up i guess but why go with 530 for the strenght because of the swing arm

 

I always love reading posts like this. What is wrong with the stock 525? I'd be very curious to see how many people actually run the bike near enough to threshold to notice the weight difference between a 520 and 525. 530 is overkill unless you are drag racing the bike every weekend (but then why would you buy a 600). I think the good people at honda made a good choice in choosing a 525. If you are going to install a more torquey gear ratio like the -1 front and +2 rear (mines a +3) you might be glad of the wear characteristics of the bigger chain. Espescially if you use the bike.
