520ERS3 (for trial competitions) The drive system has a huge impact on the machine's operability, especially in trial competitions where even the slightest difference can determine whether you get a clean or an extra point. is required. "520ERS3" is based on the latest technology obtained from trial riders competing around the world.・The lightest 520 chain! While maintaining the lightness that has been well-received by the previous model, the fatigue strength has been increased by approximately 20% compared to the previous model by reviewing the material of the plate. It suppresses uneven elongation (lengthening of only one part of the chain) and provides stable performance.・Newly adopted special reinforced pins By adopting SDH pins with special surface treatment, wear resistance is increased by approximately 20% compared to conventional products. It suppresses chain elongation even under difficult conditions such as wet races and stream sections. - Plate chamfering By chamfering the end face of the inner plate that engages with the sprocket, the biting resistance is reduced. The sprocket is spaced well apart, contributing to reduced friction and weight reduction of parts.
