Re: 520 chain and Sprocket conversion

I'm about to replace the chain and sprockets on my '99 900rr and was thinking of making the conversion from the stock 525 to a 520. *Is it worth making the swap? *What are the benefits?

Your thoughts.

Pro, Ligther....will spin up quicker! I hear stronger but can't confirm.

Con, Will wear quicker. (˘hu-˘hing)

Re: 520 chain and Sprocket conversion

My opinion: unless you're racing, I don't think you'd ever feel the difference in acceleration. 520 is slightly cheaper, but will wear out quicker even with meticulous maintenance. With casual maintenance it'll be gone very fast. I like to ride a lot of miles, so the lighter chain makes no sense to me.

Re: 520 chain and Sprocket conversion

I will report back after I use it for another 20.5k miles, matching the 21k I got out of my 530. I can guarantee you it is MUCH lighter and makes an awesome gear whine that sounds like the RC51's cams.

NOTE: I also have a 15T front sprocket - not sure if that contributes to the gear whine at higher RPM.

Re: 520 chain and Sprocket conversion

Well, a 530 stock vs a good 520, the 520 will wear longer and need less adjustments. After my stock chain kinked at 18k miles, I did the conversion. Since the conversion with a DID VM X-ring gold chain I have doubled my chain adjustment interval by about about 2 to 3 times more miles depending on riding. I say go for it, but just get the best chain you can get your hands on. I can say I did feel alittle more accel and response after the conversion, but that could have alot to do with the fact my old chain was shot. The weight diffrence between the two setups when you hold them was pretty noticable.

Re: 520 chain and Sprocket conversion

Who are these people saying their 520 chains wear out faster. I haven't seen it. Like stated above, I only needed to adjust my chain two times last year. With the 530, I adjusted my chain every month.
Kookie: The reason your sprocket makes more noise is that the stock countershaft sprocket had rubber suppression discs bonded to each side. The new one does not.

Thanks for the tidbit, but I already knew the reasoning. *I am not complaining, I am ecstatic - I love the sound!

Re: 520 chain and Sprocket conversion

My Regina 520 (top-of the line model) didn't require a chain adjustment in a full season of racing.

No downside to the conversion except maybe money.

That's probably more of a testament to good throttle control rather than a 520/530 comparo....

Re: 520 chain and Sprocket conversion



Actually, that might be a bit misleading as I did of course have to change wheelbase a few times when I changed gearing...but it never needed adjustment once it was set.

Re: 520 chain and Sprocket conversion

Wear wise, all else being equal, the 530 will last longer. The 520 is 1/8' narrower which makes all those pins and rollers narrower/lighter. That of course means there is that much less surface area to transmit the load and therefore will wear out quicker, again, all else being equal. I would say if you are racing or REALLY fast on the track, go for the 520. If you are an occasionaly track goer or street rider, the 530 is a better buy.

Re: 520 chain and Sprocket conversion

Interesting perception Bob. I on the other hand would rationalize the 520 to wear LESS (not proven, just a theory). Lighter usually means less impact on the rollers against the sprocket surface, reducing the need for it to as wide as a 530. The heavier chain would receive much more punishment during its orbital revolution cycle upon gear changes due to the mass (jerking, even though minute with a skilled rider).

Are your statements based off of tested knowledge or opinion, as mine are?

Re: 520 chain and Sprocket conversion

The chain isn't what wears out faster...the sprockets are. If you use an aluminum rear sprocket, it will wear out VERY fast. (This is for street riders.) I would suggest that new style sprocket that has the aluminum carrier with steel replaceable sprockets for the street rider.

As for the chain, if you get a VERY GOOD 520 chain, they have almost as much tensile strength as a comparable 530 chain. I also got the DID high dollar chain, and it's holding up superbly!

Kookie,

I agree with CBRBob on this one. The 530 offers 50% more surface wear for the sprocket and chain interface, which is where the wear occurs. Your point on the mass of the 520 vs the 530 is significant, but the difference is not 50%. One other significant point is the 530 offers something like 50% more volume inside the rollers for sealed lubricant.

I've asked the question on this board before, and never heard of anyone getting 20k miles on a 520.

Having said that, I don't knock anyone for making the conversion, particularly if they're racing or doing lots of track days. All I'm saying is the research I've done indicates the 520 will NOT last as long as a 530, all things being equal.

Re: 520 chain and Sprocket conversion

I will sell you my set. It has 25 miles on it. I have decided to sell the bike. Its the DID ERV2 chain with AFAM rear and Sprocket spec. front. Its the best stuff, yours for $150.
