crkidWell right now i have DID's top of the line 520 ert2 which is on there race bikes. This chain seems to be wearing pretty fast. I don't won't a o-ring chain and i'm thinking about an rk chain. The newer the model gets the less weight it is but on the backside the tensile strength goes down. So my question is what non-oring chain that is gold will out last this DID? I'm thinking the RK GB520MXZ3.

There are a number of things that can affect chain wear rate:
-Chain too loose or too tight (too tight is worse)
-what you are riding in (mud and sand are hard on them)
-lack of proper chain lube and cleaning
-worn sprocket teeth

My son uses the DID and its held up ok. What kind of life are you getting from it?

I use the Silkolene Pro Chain Lube which i highly recommend. I clean sprockets and chain after every ride so there isn't any of that old black lube on the sprockets.
I'm in the clay and don't ride in the sand or mud. What is the best Non-oring chain?

And force i don't like the o-ring chains because they are so heavy and big.

That sprocket you gave me is still on there and it doesn't show much wear at all.

Yeah i love the o-ring chain, cant believe how long it's lasting also with the sprockets looking good. the chain and sprockets still look exactly like it looked when i bought it.

O-ring chains cause drag until they are warmed up enough to where they work like a non o-ring chain. I never see anyone at the track with an o-ring chain, mainly trail riders use them. I would try the Renthal R1 or one of those, I have the R1 on my 150R and its been fine, I need to replace the one that came on my rmz and will probably stick with renthal, also how long have you used this chain?

how much weight can you possibly save on a chain. like a pound?

I run sun star sprokets with this chain i think is the chain i have, all i know is my mechanic told me it was $190 and had no o-ring. 1 sc let me find the one

I have never had any wear issues with the DID ERT/ERT2 but if you are having longevity issues I think you might want to try a sealed chain. I like to think of chain and sprockets as a whole even with a good chain the aluminum sprockets will cause premature chain wear and an old chain will cause the sprocket to wear.

A couple of very good set ups are:

The Sidewinder smart chain and Ti 2 sprockets. If you have the money to initially invest this will most likely pay for itself several times over when compared to aluminum sprockets.

The RK GB520MXU which I've heard is an awesome chain and Iron Man sprockets .

-I used the Iron Man with the DID ERT and had twice the chain and sprocket life over aluminum sprockets.-

I think you will find the GB520MXZ will wear about the same as the ERT.

crkidWell the race chains like i have on there right now are suppose to be higher quality. Also every side plate is gold so it looks trick. Maybe the rk chain will last longer.

That's why i like that kind of chain!!! Only if it wore like an oring.

That looks like a primary drive sprocket, which I have used, if so I have had some initial chain stretch issues using them as well over some of the higher priced sprockets. I don't know if the teeth spacing is slightly off or what.
After the initial stretch the chain and sprocket seamed to wear ok. It is a good alternative if you are doing a lot of gearing changes or for budget requirements.
But I wouldn't expect the same wear as with a higher quality sprocket.

I can't get the full pic to load, but the smaller one looks wayyy better than the MSR Regina chain I got goin right now.

I'm thinking this chain now.

Dang Mark, Do you just remember this stuff or are you reading from old notes you made/ I am always impressed with your knowledge.

yzwoodsRemiend you of anyone DAG?

SKIPPY!! i awnserd woods question :D BUt i like mark he is very very nice/polite and he is like a friken dictionary for bikes. LMAO!!! :D

crkidI'm thinking this chain now.

That is a great chain as I said I would pair that up with the Iron Man Sprockets.
You should get at least twice the wear of aluminum.

The quality sealed chains don't weigh much more than the non sealed, you probably won't notice the weight at all, the real issue with them is in the past there was some bit of additional chain drag. With the newer chains like the MXU this is not an issue for the average rider. I would not hesitate to put the MXU on my bike with one caveat you need to put high quality sprockets on with it to get the most out of it.

Dagget, most of this is from memory and years of trial and error and studying. I have several binders full of articles cut out of various magazines that when I'm home I will use as resources plus I've got some logs of what I've tried. Before I buy a product I will do a lot of research about the product and the design characteristics
of the product.
Most of what I wright is from hotel rooms in Asia, right now I'm in Narita Japan in fact I just got back from doing an overnight trip to Hong Kong trip.

WOW i really want to meet you MARK, your seem like a really cool and very polite guy, plus your smart as a whip with bikes. :D and you travle i bet you have some cool stories from where you have travled. :D

Mark47mx4ever,
Most of my really good stories are from my days as a Naval Aviator. Flying international out of Japan I mostly see airports, but I have been to mainland China twice, Hong Kong twice and Taipei once in the past week.

It would be great to meet you as well, I'd love to see you race.

that would be so cool, man when do you ever get free time with that kinda schedule, :o busy guy. :) but i am sure if i save up some money i could fly out, i wish i could fly out and meet everyone. :D
