Description Item #DID000S

D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere.

The D.I.D ERT2 chain is the most trusted chain in Supercross and motocross racing because of its reputation of meeting the high quality demands that are required when pushing the limits. It was designed with the intention of making a chain that is optimized for the purpose of racing. D.I.D beefed up the ERT2 chain by increasing the pin size by 3% to give the chain an average tensile strength of 8,100 pounds. Increasing the strength of the ERT2 chain did not come with a sacrifice of weight, in fact DID was able to shed 5% from the previous ERT chain.

  • Exclusively designed for motorcycle racing.
  • High-performance, lightweight and low friction chain.
  • 3% bigger pin diameter and 5% lighter than former ERT.
  • Provides the highest wear resistance, tensile strength and impact resistance.
  • Average tensile strength of 8,100 pounds.
  • Wear life index: 430.
  • Rated for up to a 450cc motocross bike.
  • Weight (per 100 links): 2.99 pounds.
  • Includes a clip-style master link.
  • Notes: ERT and ERT2 Connecting Links are not interchangeable. Non-sealed chains require more regular maintenance than sealed (O-ring, X-ring) versions and are mainly recommended for off-road use.

Good as Gold

I bought the the DID ERT2 Gold chain for my 2015 WR250R. The gold chain looks super cool up against the blue of the bike. The chain is performing well. Minimal stretch and easy to maintain. I don't second guess my decisions, i just purchase DID every time.

So sexy

If you don't already know these chains are the real deal, good price for what you get, which is uncommon this day n age. It looks so sexy on a darker nine with that gold making it pop, performance and break in are great n they last. Most common mc chain by pros so you know you can't go wrong.

Look at that gold pop! Sexy

Best Non Oring chain

The ERT-2 holds up longer than any other chain I have tried I am using it on a a 300cc two stroke and it is the perfect application. The plating holds up great and looks great as well. When an O ring chain has a little too much drag for your application this is your chain.

Q: Can you take links out of chains before sending?

I need a 114 link chain and I do not have the equipment to take chain links out

A: No we do not cut the chains before shipping. We do carry chain breakers or if you have a grinder you can grid the head of the pin off and pull the chain apart.

Q: Are all DID ERT-2 chains gold?
Over 6 years ago
On this website http://www.motosport.com/dirtbike/product/DID-520-ERT2-GOLD-CHAIN-120-LINKS/?catalogId=101393 it says DID 520 ERT-2 120L. Is that chain still gold or not? Thanks

Q: Is the ERT2 compatible with 450fs?
Over 6 years ago
The reason I ask is that DID's website says that it's for max CC of 250 but I see some guys here using it for 450s. Can some clarify this at all?

A: yes the ERT2 is can be used on the 450s.

A: I used it on a CRF450 in motocross for 20 hours and it is toast.

A: Yes, this chain will work just fine for your 450. It's rated at 8100 lbs. and is without a doubt stronger that the OEM chain your bike came with. Check the D.I.D. website for more specific information on their chains if you need to but you won't be disappointed with it's performance.
Also, keep in mind that this is a NON-SEALED chain meaning it has no O-rings as most factory chains are sealed these days. It will require more maintenance than a sealed chain but will have less drag meaning more power to the wheels!

Q: Gold?
Over 6 years ago
does the gold mean it wont rust?what chain do you suggest for gncc/hare scramble type riders?

A: No, the gold will still rust if you dont take care of it. I race GNCC and I always run a X-ring chain. It is a little heavier but you dont have to adjust it very often.
Darryl916
2 years 11 months ago Location: Budds Creek Maryland
A: I have the ERT2 on my 2012 CRF 450 and I would say go for something with an O-ring or X-ring. They last much longer. For hare scramble abuse I would not use a non O-ring chain.

My recommendation would be the D.I.D VX2 or Renthal R3
