EK CHAIN 420SR 12/50 Chain Kit - Standard Sprocket
Designed for daily urban commuting, this EK 420SR chain kit combines a 12-tooth sprocket and a 50-tooth sprocket for a transmission suited to small displacement motorcycles. The SR series focuses on dimensional stability and flexibility maintained over the miles: the plates benefit from a specific heat treatment to enhance durability and wear resistance.
Compatible with the BETA RRT 50 MOTARD TRACK (2012 - 50 cc) and other vehicles accepting the 420 standard, this kit will suit riders looking for a robust chain for urban use. Remember to regularly check the tension and lubricate the chain to preserve the longevity of the drivetrain.
