EK Chains has pushed chain technology forward with its 3D range, built on precision geometry. The concept is simple. A chain’s strength depends on shape as much as material. Every plate in the 520MXR, 520RV, and 525/530 L-Series is cold-forged, not stamped. The process compacts metal grain at a molecular level, creating plates that are lighter, stronger, and more consistent.
Each plate edge is chamfered to remove stress points that can trigger cracks. The outer plate’s smooth edges reduce wear on chain guides. The inner plates benefit too, handling repetitive flexing without fatigue. EK’s CRH-treated pins add durability, combining a hard Chromium Carbide coating with a softer core that absorbs shock.
The 520MXR takes it further with a flat-plate edge finish. It runs cooler and cleaner, slowing down wear over long rides. KTM’s racing teams have relied on EK Chains for over a decade. Mechanics report stable chain tension and predictable elongation, meaning less time adjusting and more time racing.
Supersport teams like BC Performance Kawasaki use the 520RV for its light weight and aerodynamic shape. EK’s 3D technology delivers real performance gains for motocross, enduro, and racing applications. Available through A1 Accessory Imports across Australia.
My two cents…
EK Chains basically looked at the humble bike chain and said, “Yeah, but what if science?” Their 3D range isn’t your granddad’s greasy loop, every link in the 520MXR, 520RV, and 525/530 L‑Series is cold‑forged, not hacked out in some press. Translation: lighter, tougher, less drama on the track. Chamfered edges, smoothed plates, and pins with a split personality, armor on the outside, shock absorber inside. The 520MXR even stays cooler and cleaner, like it knows about skincare. KTM’s mechanics love it, fewer wrenching sessions, more throttle time. BC Performance Kawasaki swears by it too. Fancy science. Fast bikes. Available Australia‑wide.
