Any recommendations for a 520 chain?

I'm looking to do the 520 chain conversion on my R1. Anybody have recommendations for which chain to go with? Thanks.

I would say DID. Most chain manufactures offer chain conversion kits.

RK offers a kit part number 1203-0105 that takes the front down one tooth and keeps the rear the same teeth, 520 kit with steel sprockets.

Regina offers a kit to. Otherwise looks as if you'd have to make your own with the sprockets and chain.
I have the Part Unlimited Catalog on CD at home so if you need part numbers I can look then up.

The best chain you can buy is the DID Erv2 (they now make the ERV3).

Unless you are racing your R1 save your money and time. Your not going to notice any difference on the street excapt that you will wear out sprockets faster and a broken chain sucks!

Are we there yet?

I would not reccomend a 520 chain and Alum sprocket combo for any bike 1000cc and up. The power just eats them up. Consider a 525 chain as it's more reliable. Jim

I'd have to disagree.

Most people when doing the conversion also change gearing. I believe I went 2 up in the rear and it made a big difference on my 2002 SVS. Definitely worth it. Tomorrow I'll hopefully be installing my 520 conversion for my R6 going -1 in front and -1 in rear. It's one of the better bang for your buck mods.

+1 on the larger bikes eating them up though.

I'm changing the gearing on my R1 b/c in stock form the gearing is terrible for the local tracks. I guess I could go w/ 525 size. Is the 520 chain really that weak or is it the sprockets that don't last???

520 is a BIG mistake for any big bore bike for the street. The 520 chains can't handle the HP for extended periods (ie., street bike) and the weight savings isn't anything. For race bikes? Unless you're an expert and/or going for a championship or track record you WILL NOT notice any advantage with a 520 chain and sprockets.

1. You can change your sprockets (gearing) and stay with your 530 chain. A 525 is good as well. 2. I switched to a 520 on my CBR's and honestly, I'd bet you tall dollar you couldn't tell the difference whether you're on 520 or 530.

Buy new sprockets if you want but - switch to a 520? Save your cash for tires or an Arai or some track time.

If thats what your looking for i would say leave the stock gearing. it is suitable for any of the tracks around here .You have to rembember a R1 has a bunch of power. You don't have to use all the gears at the smaller track and at Road America it won't pull the stock gearing anyway.

A good rider could do 9's at blackhawk with stock gearing.

most r1 riders change the gearing for the track. with the 520 conversion go -1 in the front and +1/+2 in the rear. as for the 520 chains not lasting on liter bikes if your not stunting you should be fine. check out r-1forum.com for what people have done with the same bike.

I tend to listen to 4&6 on most of this stuff. They obviously have the experience.
But I will say, that I did the 520 conversion because on my 2003 gsxr 1000 and haven't had any issues. I pretty much had to because the Marvic wheels that I got off of ebay supposedly only run a 520 sprocket, at least that's what the seller told me and he is the west coast rep for dunlop tires, so I figured he knew what he was talking about.
The chain has lasted one season with hardly any stretch at all.
I probably would agree with those that say you won't notice much of a difference though.
