520 chain and sprockets

looking to get a new chain/sprockets for my 05 10r. i've already got a -1 in front, looking to go up 2 in the back. my bike has 4400mi on it, i got the -1 sprocket about 1k mi ago. should i replace both sprockets and the chain if i get a new rear sprocket? also, what are the advantages of going 520? i've heard they are lighter, so they spin faster with less strain on the motor. is this a recommended mod? i'm gonna be going to 4 track days over the next 2 months, and i'm looking for just a bit better drive out of the tight corners at t-hill. also, where is the best deal on these parts? thnaks guys!

mmmm given the 16t is fairly new i'd replace the chain & rear but use 112L so the axle gets moved back.
I never tried a 520 on mine but others have with mixed results so maybe they will chime in with their 3cents but yes with an aluminum rear & 112L 520 chain the reduction VS the OEM is roughly 1-1.5lbs.
Post a note in the sponsor section for pricing.

replacing the rear wont trouble you one bit. i converted to 520 on my r6 but also went -1/+2 so i couldnt really tell you the exact dif the chain made.

If you're doing 4 track days in the next 2 months....you're in for more

before the end of the year.....

Even if you ride street-track I would recommend a 520 conversion, less

weight and (relatively)cheap horsepower.

I have -1 +2 on my '05..that works pretty good on most tracks here in

SoCal (Buttonwillow,Fontana, Willow Springs, Streets of W, Pahrump).

Should be good also for Thunderhill.

Also like BD said, while stock chain is 110 links, cut yours @112 coz the

(41t.) sprocket, also gives you more wheelbase.

Chain: I like (DID)ERV 3.....sprockets: Driven or Afam.

Stay away from Vortex..

Changing to 520 pitch on the 10 won't make as big a difference on the 10 since the 525 pitch is already pretty light. But if you like to mess with your stuff, as I do, it won't hurt anything either. I switched to 520 on the 10 like I have on pretty much every bike I've owned besides the 'bus and have had no problems whatsoever. I used the DID ERV3 chain and AFAM sprockets and went +1 on the rear for the street and +2 for the track.

...not sure if you meant switching to 520 on just the rear and keeping the 525 on the front for now but if you did I wouldn't mix sizes like that. Especially for relatively hard track use.

yes you could but no you should not as the chain has 4.4k on it and to introduce 1 new sprocket to a chain with wear is not recommended.

You will have to keep a very close eye on the 520 though. I have one on my 06 and it streches alot. I only have about 1,200 miles on it but boy, I have to adjust it constantly. I will be going back to the 525 real soon. Also it is a non o-ring and, of course, it must be lubed after every use. I will go with the x-ring 525. I am only 160lbs and thought it wouldn't strech that bad. I am almost out of adjustment on the swing arm.

what kind of chain do you have on there now? I might have misread what you were saying by "non o ring" but if it's what they call a roller chain, or it was very cheap, it's going to stretch like like a rubber band

Either you bought a cheap, POS chain or you spend all your time doing clutch-up wheelies and other gay stuff. Like I said above, I've never had any problems or excessive stretching even on liter bikes. The chain and sprockets on my 10 have about 4k miles on them, including 5 trackdays and they're still in good shape.
