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.

I love these chains I run them on all 6 of my bikes but …
The chains 3 times now have came in with no master link because the heavy chain beats the boxes up and it falls out or something very frustrating I’ve had to return them each time and hope the new one is better I don’t see the point in paying 15$ for a master link when you already paid 50-60 for a chain and putting a cheaper link would make getting the DID pointless just tape the boxes better or clip the link on one side of the chain jeez

Quality and looks!
Used on my 2018 KTM 350 XC. Went from an x chain to try something lighter. Looks great and should be happy with it. We will see how long it last. Had to cut 2 links out but super easy with a grinder. Definitely lighter when comparing to the x ring did chain! Gold should make it look cleaner for longer. Definitely the best price around!
