EK/PBR 420SR Chain Kit 11/52 - Standard Sprocket
Designed for urban use and small displacement motorcycles, this EK CHAIN kit combines a 420SR chain with an 11-tooth sprocket and a 52-tooth steel rear sprocket. The SR series focuses on a design that maintains the chain's flexibility even after many kilometers: the plates undergo a specific heat treatment to enhance strength and longevity without compromising the flexibility needed for smooth transmission in the city.
Ideal for urban riders seeking a reliable transmission for their 50cc motorcycle, this kit is well-suited for common replacements and maintenance checks (regular tension and lubrication recommended). Compatible with many 50cc models, it is particularly suitable for the RIEJU TANGO 50, TANGO 50 MOTARD, and SPIKE 50. Manufacturer reference: Not provided.
