Great “non O ring” chain for racing
This is a great quality non O ring chain. For those who don’t know it won’t have any rings with the master link. It has no O rings at all. Picture on the box shows that as well. This is for racing. I’ve been running DID since the 80s (86 250R ATC). Always top choice for chains. This chain is going on a 2013 RMZ 250.

Great Standard Chain for the Money
For the dirt bike crowd, this is a great no nonsense, high quality affordable chain. Highly recommend. This is a standard chain and not an o-ring chain. At 60.00 and two-day delivery, just an outstanding value. I ride MX on a Kawasaki KX450 almost every weekend and I love this chain. Keep in mind you will likely need to shorten it to your required length. But, this is normally required for all chains. Invest in a high quality chain brake tool and you will be set. Five stars !

DID chains high quality even from this inexpensive chain.
It’s a great chain “ I have always used DID chains on my bicycles and motorcycles and I have never had one fail. I have 250 miles on the chain and it really never stretched on me. I did not have to readjust the chain yet it is a way better chain then the stock chain on the X Pro 250 Templar, it is so much quieter then the stock chain was. “ make sure you follow the directions and prepare the chain properly or you may not get the performance you should “

Wrong size
Got my order real fast as usual. When I went yo-yo chain on my bike, I realized it was not the correct size. This chains made for a mini bike size motorcycle. I didnt realize this at time of ordering, it I was not given an oppurtunity To choose between different sizes, I just assumed it was the right one. So be careful make sure this doesn’t happen to you. The motorcycle I was working on was a projection bike do I didnt get around to installing right away. For whatever reason there was not any way to send it back and get credit and have the right one sent. So I now have a totally useless chain. This to me is a problem with this online shopping thing. Also I was looking at my past orders and realized half the things I’ve gotten where all terribly made quality, and are no longer even working if they ever did. And there’s no where to go to complain, so it continues on. We the consumer are getting the short end of the deal. Although the chain they sent was really nice, if it did fit I’d be happy, but it doesn’t so Im not. Maybe I’ll go buy a small little motorcycle. I dont know what ID do with it but atleast if have a place for my chain. Ive also considered cutting it up making necklaces out of it. If in a year the newest fad is wearing dirt bike chains around your neck, it started here.

It worked as expected.
Yep, it works. I mostly bought this just for the retention clip.
