D.I.D. - 520 ERVT Chain

The D.I.D. 520 ERVT Chain is built for riders who want one chain that truly does it all — lightweight, strong, and built to last. Part of D.I.D.’s Exclusive Racing Series, it was developed for off-road rally and enduro racing, where every ounce and every mile matter. The patented X-Ring technology cuts down friction and stretch, giving you smooth power delivery and a noticeably longer lifespan than standard sealed chains.

Why we like it: it’s D.I.D.’s most balanced 520 chain — tough enough for race abuse, light enough for fast throttle response, and slim enough to fit bikes with tighter clearances like the Honda L Series. And honestly, we also like it for the way it looks — that full gold finish just makes any bike look factory fresh.

Why it’ll work for you: the 520 ERVT’s lightweight design and high tensile strength mean more efficient power transfer and less adjustment over time. The X-Ring seals keep dirt out and lube in for consistent performance mile after mile. It’s D.I.D.’s lightest, longest-lasting 520 X-Ring chain — and it looks as good as it performs.

Key Features:

  • The 520ERVT is designed as our top-of-the-line enduro chain, but it's strength, lightweight, and extended chain life makes it an ultimate racing chain.
  • Born from our original non-o-ring motocross chain, the ERVT boasts our patented X-Ring technology which provides less stretch, a higher tensile strength, and ultimately a longer lasting chain.
  • This is our lightest and longest lasting X-Ring chain in the 520 size.

Durable and a must have for aggressive chewers
Color: Blue+Red
These are without a doubt the best toys that I have ever purchased for my dog. He's an aggressive chewer and quickly destroys almost every toy I buy. This one hasn't been destroyed yet and the squeaker is still working at about 5 months.

GSD Winner
Color: Blue+Red
10/10 recommend for big dogs with a tough chew. Our GSD absolutely loves these squeaky balls. They have perfect texture for his teeth and for our grip. They are the size of a baseball and are so durable and fun. Yes the squeaky is LOUD but he loves them so much that it's cute

Great buy
Color: Blue+Red
My dogs kill every toy. They arrived very agressive chewers. These have lasted way longer than most balls have. Great value

If your dog loves tennis balls, you NEED these
Color: Azure+Orange, Color: Azure+Orange
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better! These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!

Really are indestructible. Amazing product.
Color: Blue+Red
Wow! Really indestructible. Our large dogs have destroyed other “indestructible” toys in less than an hour and these are amazing. They squeak, which our dogs love (we hate) and they float when they go into our pool. IF they ever do wear out or are lost I will definitely buy again.
