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 D.I.D was able to shed 5% from the previous ERT chain.

The pins on the ERV3 X-ring chain have been put through a patented heat-treatment process to produce a pin that is 1.5 times harder than conventional pins. The result is a chain that is significantly stronger and offers better wear resistance than many other chains on the market. D.I.D ERV3 X-ring chains feature a gold-plated finish that resists rust and adds a little style to your motorcycle or ATV.

  • 120 links.
  • Note: The Renthal R4 chain is supplied with both an easy-fit split master link and a superior solid-pin rivet master link which matches the durability of the chain.

Note for installing O-ring chains: As O-ring chains are wider than standard roller chains, when fitting an O-ring chain to a motorcycle that was fitted with a non O-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.

PT chains and sprockets hold up really well to the torque of the 450s. good wear out of them. You can just look at the sprocket and see that is is built better than a renthal.

Longer Lasting

So far I am quite impressed with the durability of this chain in sprocket kit. I went with the X-Ring chain, which was new for me. However, I gave it 3 stars for ease of installation because my buddy's dad, who has worked on bikes for many years, even said that it was the most difficult master-link he had ever installed. Also, I've noticed after a few rides that the sprocket gets this really thin silver mark below the teeth almost as if it is rubbing or warped. The sprocket teeth have lasted a lot of rides and is still in really good condition. If you want something that lasts longer I recommend this.

I have these sprockets on my 2010 yz450f and i ripped all the teeth off?
SO im just wondering if these have been upgraded or anything or why i could have ripped them all off cause i always keep my chain to the tightening spec that it should be. maybe it is just because i am not running that good of a chain i don't know but my question is will the DID ERV3 X-Ring chain and the Pro-taper front and back sprockets hold up the only thing done i have to my bike is a full FMF 4.1rct with the Megabomb header so it doesn't have so much power that it just eats sprockets?? Please answer!! My front sprocket seems to be fine its just the back that got ate for some reason?

Any aluminum rear sprocket will not last last as long as a steel sprocket, the countershaft sprockets are made of steel which is why it is outlasting your rear sprockets. Riding conditions and how often you lube the chain can greatly affect the life of an aluminum rear sprocket. If you ride in sandy or muddy conditions they will wear much quicker than a steel counterpart. Also a like you mentioned, a lower quality chain can also affect the lifespan of sprockets. The DID ERV3 Is an excellent chain and is highly recommended, but for the best lifespan I would pair it with a steel sprocket. There are standard steel sprockets available, a hybrid option from Renthal called the Twinring that has an aluminum inner portion with a steel outer ring and teeth, and then there is is the Sunstar Works-Z Stainless steel sprocket. The Sunstar stainless sprocket will last 3 times longer than a steel sprocket and has a lifespan 10 times longer than an aluminum sprocket. While the stainless sprocket costs a little more initially, it definitely recoups the cost by how long it will last.

Make sure that your wheel alignment is correct. Slightly offset will chew up sprockets and wear chain really fast. Don't rely on axle blocks, measure to a fixed point with tape measure.
