Was looking at my new to me TW200 today, and noticed the chain is stamped D.I.D 428, is that a stock chain, it does have a 47 tooth sprocket, so fingers crossed that it is aftermarket!

Be nice if it was, saves you 70$ and it should easily last 20k miles at the least. Might even outlive the bike! My O-ring chain & sprockets are at 4,500 miles now and all are still like new, in function at least. Chain looks a little dirty cosmetically but it's still fine!



If it the stock chain, may as well run it until it's wasted and get yourself a whole new drive system - 14/47 sprockets if you're mainly using the TW for street riding, and a nice O-ring chain. Whole package shouldn't cost you more than 100$.

The 47 tooth sprocket would make me think it's aftermarket, but without being able to see it . . . . . it should be easy to see if it's o-ring or not, if so, you scored.

D.I.D. makes about a dozen different chains in 428. Some good, some great, some suck.

428 V o-ring chains: 130, 124, 122 links? I am getting new sprockets, 14/47,48 or 49. I've read the older models run 14/49? I have a 2010 that i'd like to run at a little lower rpm at 65-70mph and to possibly make it through an intersection in first gear after a red light. What length do I need?

Whatever fits. Stock length is given as 120 or 122 links. 120 fits those TWs that came with 14/45 sprockets installed in some markets. 122 fits those TWs that came with 14/50 sprockets installed in other markets. Different OEM sprockets explains the different chain lengths. It has been reported that 122 links fits 14/47 sprockets just fine.

Is KMC a good brand? I found a few on ebay for $40 + $8 s/h but they are gold. Or should I just bite the bullet and buy a DID for twice that?

The three KMC 428 chains in the link you posted have claimed tensile strengths of 1800, 2000, and 2300. Looks like even their best chain is garbage.

sqwerty is on the money again. Looked into KMC here and turned away for this reason.



The best alternative to DiD for = $100 is I can find here is 200-428SRO-132L EK O-RING CHAIN R 563.00 = $70



It looks quite good 5300 lbs. for 428SRO

Any experience with EK?



If you look at the company history it seems that they lead and DiD follow. Imitation is the most sincere form of flattery.

I dunno where you kids went to school, but at the reform school I dropped out of 2300 kg. is a few clicks over 5000 lbs.



Just sayin'.

I missed the units. Are KMG o-ring chains? If not, I still wouldn't use one.



I don't think EK makes a 428SRO chain. Are you sure you're not looking at a 428SROZ chain? If so, it's a good chain. Tdub just got her third. Her last 428SROZ chain lasted 26,000 miles.

DuH! so DiD I. Pun intended.








It is an o-ring and comes at $57 as opposed to the DiD O-ring for $87.5 and X-ring for $100. Of course my currency has weakened of late so all prices inflated in the translation, but have not changed locally since. They are also nickle plated so no rust if lube neglected and a more sexy look. Methinks I must invest before the price hike.



BTW the prices I got on EK were higher than KMC and I just discovered wholesale and not available to me - have to go through the dealer, so KMC wins the retail research prize - unless anyone has any undiscovered info. As the economists say ceteris parabis (assuming perfect knowledge). That heavy duty open chain with similar tensile specs comes to me at $16 and is great value for a pavement bike or for the cash strapped who can clean and lube often.

That's the best deal I've seen on an o-ring chain ever! I might order one just because.

It is $57 shipped to me which is exactly what the local price is so here we have a perfect market of rational choice.
