You can find ERT3 520x120 chains on ebay for a really good price. Just get a cheap chain breaker and you're golden. https://www.ebay.com/itm/D-I-D-520-ERT3-Motorcycle-MX-Race-Chain-520-12…
I ran the ERT2 on my last set of sprockets. It was a great chain with super low drag, but it did stretch a bunch. Just put the ERT3 on my bike now but haven't ridden with it yet.
The DID ERT2&3 chains seemed to always need to be adjusted and the GOLD color looked worn out after a few rides. The RK has 20 hours on it and is still looking good. I’m done with the DID chains, there is better chains avaikable
I have always used the DID ERT2 for years and noticed lately that it seems to be stretching more than usual and thought I was just getting old... I might pick one these up and try it for my 450.
