JT Chain JTC520X1RGBSL (520 Series) Gold X-Ring Clip Type Connecting Link

First of all this IS a very high quality X ring chain just as advertised. It is as good as any Japanese made chain I have had. It is definitely on par with Renthal chains and seems to be stretching less at first. It also comes with two master links. One is the clip on kind that requires no special tools and the other is the rivet kind that is more secure but takes special tools to install. The description only says it has the rivet type but their website says it comes with both types and it is accurate. I was not expecting such a high quality chain to be honest because I got it very cheap. On the first ride it "stretched" about a quarter inch. My next ride was much harder and longer and it did not stretch. Most of my new chains need adjusted after each ride for about four or five rides and then they settle in so this one is very high quality and does not need much settling in. This is my first x ring chain and I am pleasantly surprised at the difference in drag from an O ring chain. With the X ring chain I can spin the tire on a stand and it spins almost like a chain with no rings of any kind in it. It really is the best of both worlds. It is sealed and protected but has very little drag. I ride motocross so it is absolutely perfect for me.My only concern is the heavy duty grease that came on the chain. It is very thick and won't come off your hands without some kind of petroleum based soap or kerosene. I have never seen grease so heavy duty on a chain and it gets dirt in it and does not look good. I could probably just get it all off with kerosene and then oil the chain normally but I don't want to mess it up so I will leave the grease on until it wears off and continue to oil the chain over it.I also seemed to have gotten in on a glitch. I got the chain for much less than half price so I bought two of them. The next day the price went back up. I was dreading Amazon contacting me to tell me they made a mistake and I would have to pay more or not get the chains. They did not. I was thrilled to get them in the mail and it was exactly what was advertised.

I’m used to DID chains so I was a little caught off guard how much it stretched at first. I had to adjust it every time I rode it the first 3x. After that it seems to be holding up. Just did a track day after about 5x and didn’t have to adjust once.

Fit perfect on my stock 2021 Raptor x ring D.I.D. Chain.

Contrary to the description this comes with both rivet link and quick-clip link.Pros: seems like a good quality chain. Longer term wear will be the better test.Cons: weakly pressed master link. Pins pushed through the back of the master link plate when I was pressing the two plates together.I've put plenty of clip links together with a pair of vice grips before without issue. When I pressed the side plate onto the pins of the link the pins pushed back into the main link. Couldn't get the clip on. Had to tap the pins back into the plate and retry. Link press tool is almost a must with this one.

If you have a 520 chain with 2mm thick side plates (vs. 2.2mm) this is a great masterlink. I used this with a Bikemaster 520 BMOR chain on a DR-Z400. A little tough to squeeze the plates together to install the clip, but you want compression on the x-rings, so perfect.

Worked as it should. Haven’t ridden yet, to see how it holds up.

2005 Honda CRF250R: I paired this chain with JT front and rear sprockets 51x13 designed for this bike. This chain snapped on the first time use going up a hill climb. Ended up bending my shift rod and costing me $$ to replace and fix! Not sure if I got a faulty chain, or this chain is weak.

Didn't last as long as expected.
