D.I.D. - 520 ERT3 Chain
D.I.D. - 520 ERT3 Chain
We like the D.I.D. 520 ERT3 Chain because it’s the kind of upgrade that instantly makes your bike feel tighter, faster, and more connected to the throttle. It takes everything great about the legendary ERT2 and cranks it up — more strength, better shock resistance, and smoother power delivery, all without adding weight. This thing can take a full season of abuse and still feel fresh, which is exactly why it’s trusted by factory race teams around the world.
For everyday riders, it means less stretching, fewer adjustments, and more consistent performance every time you roll on the gas. The SDH pin treatment hardens the surface to handle brutal loads while the soft core absorbs impact, so it stays strong without feeling harsh. Solid bushings add to the longevity, and that gold finish isn’t just for looks — it keeps corrosion away while giving your bike that clean, factory style. It’s the kind of chain you put on once and forget about, because it just keeps doing its job, ride after ride.
Expert riders will like the D.I.D. 520 ERT3 Chain because it delivers the precision and reliability needed to push a bike to its limits. The lightweight design keeps rotational mass low for quicker throttle response, while the added strength and shock resistance let you hammer through whoops, jump faces, and hard landings without losing tension or feel. Every bit of power transfers straight to the rear wheel, giving you sharper drive out of corners and total confidence under heavy load. It’s built to perform at the highest level — and it shows every time you twist the throttle.
Key Features:
- ERT chain designed for motocross
- High-performance, lightweight, low-friction chains designed exclusively for racing
- Because of its strength/weight ratio, this is the go-to chain for riders across a multitude of racing disciplines, especially among the 250 class
