    After the hunt for cheap O-ring chain thread I got on the phone to Yamaha and made this discovery which warranted a new thread. Any experience with these?



    My Yamaha dealer mate can give me one for the new old T Dub for = $100 which would have worked out at $114 last week but the rand weakened. Including new sprockets its going to be $160.25 which is an expensive service but the technology seems convincing.



    The latest DID VX X-Ring chain is grey in colour and built to the same specifications as the proffessional O-Ring chain but now these are built using the fantastic X-Rings for better lubrication giving longer chain life.






    Half the Power Loss

    (Compared with Normal O-Ring)

    D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss.

    X-Ring is a U.S.A. Registered Trademark of D.I.D; Daido Kogyo Co. Ltd. Japan 1.5 to 2 TImes Longer Wear Resistance

    (Compared with Normal O-Ring)

    The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.

    I've been happy with DID chains for many years. If they have a new one that will last longer under the unrelenting power of the Dub...Great.

    X-rings aren't new, but may be new to the 428 market (well, might be new to the U.S. market as I think they're available over seas). But don't ignore the standard o-ring!! I'd love to see some actual numbers on power losses. -0.001hp is technically a loss, but would you notice the difference? I'd venture to say the average TW'er experiences a greater loss from changing environmental factors (temp, humidity, pressure) than switching from standard to o-ring. Don't get too caught up in THEIR marketing.



    Secondly, the links only twist a few degrees about the o-rings as it wraps around the gear, its not continuously spinning about the o-ring. The loss from o-rings should only be from the few wrapped around the gear. All others are in straight chain section between the gears (not spinning but stationary).

    This makes more sense:

    It is still an O ring chain, its just that the rings have edges. My guy at Yamaha says DiD o rings are "no more". I am going to shop around and see if there are any old stock ones with old prices.

    The general dealer has the o ring for $12.50 less, that's 12.5% less. If the DiD claims of double the life of the old o ring are true, then it's worth buying the new technology. It would be good to see some independent trials.

    Someone finally got it right. This should be a stickie. It's gotta be more reasonable than my demented ramblings on the subject:

    I have been looking for a 428 x-ring here in the states for quite some time. I will probably end up just buying the o-ring and give up my search unless someone else has found a reputable pplace to buy one from. Either way, i'm still trying to decide whether to stick with the 14-50 set up or go for the 14-47 when I get my new chain. Decisions, decisions...

    Sidewinder a company that makes chains and sprockets came out with a new chain design using O Ring technology.



    You might find their video(s) ranging from interesting to entertaining.



    They produce some fascinating products and have a large racing and aerospace following.



    LINK



    Note: I'm not promoting them, though I have bought from them time to time and just passed by their website about the same time this thread appeared ….So thought I would share the link.

    Tdub wears brand new chain and sprockets. Perhaps we'll be privy to some actual data rather than hype when those need to be replaced.
