Chain Size.

What stock size chain on KDX's. Do they vary from year to year? I have a 2003 KDX.

520/108 link, I THINK they are the same on most.

Ok, next question. 520 stands for the size of the link right? and the number 108 is the number of links in the chain?

Yep....

jafo, do you have the owner's manual or the service manual?? Since you are really just wanting to know about YOUR bike, just look in YOUR manual.

If you are thinking about increasing your sprocket size beond a 48 tooth, then you should purchase a 110 link chain.
BTW... Rockymountainmc.com has the Primary Drive Gold X-ring chains for around $55, I just bought one and they are nice.

Ah! Thats something I was'nt thinking of. Thanks. I just have to decide what I'm going to do as far as the drive ratio on thia bike. I'd like to change it and see what it does to the bike.Indawoods wrote:If you are thinking about increasing your sprocket size beond a 48 tooth, then you should purchase a 110 link chain.

re: size of the link
There is a lot to that....the 'size' of the link means what exactly?
It's the pitch that determines the other 'sizes' of a chain. In the case of a 520 chain, the pitch is 5/8's of an inch. The pitch is the distance between the pins.
Roller diameter and width are measurements that are derived from the pitch of the chain.
Aw shucks...let google do the walking.....
Note:

BTW...I haven't used one, but legend has it that a 48T rear sprocket is fine with the oem length of 108links. A 50T does require the longer (110L) chain.
Old song...but you can 'test' a lower ratio (higher number) by putting a 12T CSS on in place of the OEM 13T CSS. If you like it, and are of the opinion that a 12T CSS is terrible/awful/bad..then put the 13 back on and get a larger rear sprocket. No, there is not an exact match number-wise...but close enough.
..you can do the math....

Weeeellllllll smarty pants what does a 49T require then ?? And don't say 109.
Awww wait, you said I gotta do the maths... DOH !!!

109! Good guess!!
You are welcome.
'Do the math...' refers to final drive ratios..not chain lengths btw.

The above chain length is completely bogus. You knew that, right?

You know, it is kind of fun to say the-word-that-is-banned-on-that-other-site here! ebay! eBay! EBay!! Whoo-...EBAY!!!

For the wondering....
You can order chain by a specific length..and most chains you buy will have a length specification. That link number will always be even (ex: 108links). You will never find an odd number of links listed as a length.
Because the two ends (considering we are talking about a chain that HAS ends...some don't!) are joined together by the master link..both ends of the chain are the same 'gender' (if you will).
If 108 links is too short...and 110 links is too long...you will have to have KayD find you a chain that fits!

Has anyone ever seen a motorcycle chain with a half link? I saw at least one while BMX racing, but I don't think I have never seen one mentioned for motorcycles.

Great info CC. Thanks.

Just buy the 110 and there are no suprises and they are the same price... well at least the primary Drive chain was...
If you need to remove a link, grind the pins flush with the link plate and tap out... instant 108! Easy Squeezy!
One other thing....
Buy 2 Master links when you buy a new chain... one to put the chain together and one spare to stuff in your pack....It could save your weekend so it's worth the extra few bucks.

re: spare master link
Absolutely!! Believe it or not, I've often found that NO local dealer/shop/bike parts place has them available. If you need one of them...well, you NEED one.
Yep...I carry one with me.
I didn't intend the implication that an odd numbered link chain is impossible. As Jason mentions, certainly that's no mystery. BUT, that's not going to do you any good if you have a common master link that you're using to put the two ends together.
A btw..you can use your chain breaker as an install tool when putting the chain together. Some o-ring (x-ring..whatever) master links can be a bit of a pain to put together correctly. The o-rings need to be squeezed to fit the side plate..but you don't want to damage them by squeezing them too much.

I bought a TUSK Chain Press for $9.99 from RM
It's worth it to not kick my bike over and stomp on it!

I checked those out too when I was making my list. Gotta have one of those out in the field for sure. a hundred extra masterlinks won't do you any good unless you have that little tool.

Well I bought a brand new Sun Star 49-T rear sprocket off E-bay for like $12! Then i went ahead and bought my X-ring chain, extra master links, front Sproket 12-T and chain tool from R.M. today. So we'll see how this combo works out this spring. I figure if I like the 49 tooth rear sprocket, I'll get me one of those Tri-Metal sprockets later on.

Think I should try the stock 13-T front sproket with the new 49-T rear, first? Then try the 12-T front and the 49-T rear, second?
