520ERS3 (for trial competition)
A drive system that has a significant impact on the operability of the machine, especially if there is a small difference in the trial competition, it requires a solid feeling of rigidity that transmits delicate operation and instant traction.
The 520ERS3 is feedback from the latest technology gained from world fighting trial riders.
The lightest 520 chain.
The material of the plate has been revised to increase fatigue strength by about 20% compared to previous models.
It suppresses stretch (only a part of the chain will stretch) and provides stable performance.
Special reinforced pins.
By adopting SDH pins with special surface treatment, it increases abrasion resistance by about +20% compared to conventional products.
Prevents chain stretch even under harsh conditions such as lace when wetting and lots of sections.
Beveled plate
Beveling the inner plate end that merges with the sprocket to reduce the resistance of chewing.
The sprocket is far away and helps reduce friction and reduce the weight of parts.
