AZSSMUK Roller Chain Breaker Detacher Tool for Size #25#35#41#40#50#60 415H,428H, 520,530 Motorcycle Bicycle Go Kart Chains Replacement

It DOES WORK though! Its more bicycle chains cause the pin on the breaker will probably go through that hole or larger! Just doesnt fit smaller chains like pocket bikes! If you have a pocket bike you can use it, just go half way on the pin youre popping out, or itll bend your link but like I said, this is pretty much for bicycle chains or larger! Works great though!

It came quickly, was exactly what I ordered, seems to work as I need it to.

Done what it is supposed to do

100% junk it works amazingly the 1st time and if you only need it 1 time buy it... but after that its next to useless the needle is soooooo weak it looses around 2mm its 1st use off a 8mm needle making it to short to push the pin out of the chain. 2nd time i used it , it screwed up my 35 chain cause i didnt realize this now than i looked at breaker and seen what did it. Before using it i did see the needle looked dented at the tip now the tip is gone after 2 uses!! And half of a $40 go kart racing chain is screwed up not sure if i can fix it. Very unhappy

Works on standard chains doesnt work on metric

I bought this chain breaker probably about 4 years ago and I am a motorcycle mechanic and use it pretty much on the daily on multiple projects and it hasnt failed me yet and still going great value didnt have to pay that much for it but for something for that value to work this long I back at 100% very satisfied with it and still going.

Its not big enough to actually fully detach the chain on a #40 dollar chain. It can loosen the pins so you can get it apart, but if youre trying to completely remove the pin between the links, its not going to work, the pin isnt long enough to push it all the way out.

Buy this one.

I have a manco dingo go kart and I needed to replace the chain. This worked great and Im pretty sure i can use it many more times

The first time I used this thing it bent the chain links. Then when you do get it to work it won’t even push the pin all the way through. After pulling on the pin for ten minutes it had ruined my chain. NEVER EVER EVER EVVVEER BUY THIS THING. COMPLETE TOTAL WASTE OF Time, Money and a GOOD Karting Chain.
