Winning with D.I.D
The D.I.D 520ERT3 MX chain is a high-performance, lightweight, low-friction chain that has been "engineered to withstand the tough conditions that off-road tracks and rugged terrain present for transmission chains to survive and the D.I.D engineers have specified the O-Ring design 520ERT3 to survive everything that can be thrown at it".
The non-sealed 520ERT3 is the best-selling MX chain from D.I.D. "and is used by many professional racing teams in official competitions. Due to its optimal strength-to-weight ratio, it has become the chain of choice for riders across multiple MX disciplines, particularly in the 250cc class."
The high-performance, lightweight design reduces drag with O-Ring technology increasing wear resistance and longevity. "The exceptional strength-to-weight ratio makes it ideal for high-speed and demanding conditions."
D.I.D. sponsors the Kawasaki MXGP team with the ERT3 chain - "with Romain Febvre setting the seal on the 2025 FIM World MXGP MX Championship campaign (at Darwin, Australia) by clinching his second MXGP world title and the first for the Kawasaki KX450-SR.
In addition to the MXGP Championship, 2025 saw D.I.D scoop the MOTOGP title with the Ducati Lenovo Team and Marc Marquéz using their 520ERV7 chain.
