    My '02 640 Adv. needs a new chain. Since the search isn't working very well I thought I'd be lazy and just ask. Looking for a good mid priced chain and where to buy. Have new sprockets already.

    Thanks,

    Whatever you get, make sure it's a good x-ring, o-ring, or variant. They tend to last a lot longer than the non-ringed chains that some folks fun on dirt oriented bikes.

    I just went through the process of getting a new chain and sprockets on my 2000 640 Adv. I did a little research and ended up getting a RK XSO X-Ring for about $75 from Dennis Kirk. Went on fine, although I was surprised that the master link outer plate had to be pressed on. Sorta defeats the purpose of a master link in my book, although I understand most are this way now.

    I know several people who recommend the DID X-ring 520VM Gold chain. I just got one for myself, paid $91 from Thumpertalk.com store. I don't have many miles on it, but it certainly has less friction than the old, stock chain. The bike rolls much easier, it is noticeable.

    I also had to press on the master link outer plate. A $10 Tusk tool from rockymountainatv.com worked well :thumb, although it is not really necessary.

    I 2nd this recommendation. I put one on a couple of weeks ago. It's great so far. That's a good price too.

    OK, I checked the price, I paid $91.76 for a 110 link chain. I bought 2 of the clip-type master links for $4.72 each. I figured one to install the chain, plus a spare. But when I got the chain, there was already a clip-type master link packed with the chain. :baldy Oh, well, now I have 2 spares.

    Regina x ring w/ master link ~$80 off KTMTalk. DID & Regina are known to me. Some others are probably good, too. X or O is money well spent.

    I've broken 2 chains in 25 years. Both were Regina chains. May be just my luck that they both happened to be Regina, but I'll never buy another.

    And someone said they bought a 110 link one. I thought that the 640 took a 118?

    I said I bought a 110 link chain, but it was for a different bike, not a 640.

    That makes sense.

    And BTW, I've had good results with DID x-rings.

    DID 520 VM Gold X-Ring are very, very good chains, the best IMO.

    The Titanium Nitride coated side plates look nice too. Cost is about $80 on the web for 120 link length. I think the stock 16:42 ratio KTM LC4 uses 112 links but double check to be sure.

    My stocker was 110 links. Just replaced it with a 110 link DID 520VM x-ring.

    The KTM parts list for most (all?) LC4's lists 118 links, but they assume you're going to cut to the size you need. An Adventure, for example, comes with 110 links stock.

    Regina does not have a good reputaton here when it comes to
    chains for strong motorbikes. I remember them from my early
    youth, when they were 1st choice for mopeds. But a healthy
    KTM seems to put some more strenght on the chain, than my
    old PUCH Cobra did in 1978 :-)

    Somebody's gotta ask sooner or later - masterlink - clip or rivet?

    I'm a rivet guy on anything that sees street duty.

    Just out of interest, my 93 LC4 400 runs 112 links and has 14/50 sprockets, logically should be much longer eh??

    My regina went 13,000-14,000 miles , I'm not sure what the actual milage was.
    The DID I replaced it with 520VM, has now gone about 14K miles.,
