Product details :

Features

EK/JT 520M3 13/50 Chain Kit - Ultra-Light Sprocket by EK CHAIN: a set designed for motocross use, combining a robust 520M3 chain and an ultra-light aluminum rear sprocket. Ideal for riders looking for a reliable and lightweight transmission suited to the demands of rough terrains.

Configuration: 13-tooth sprocket / 50-tooth sprocket (13/50)
Chain type: 520M3, number of links 116
Color: gold / gold
Sprocket material: aluminum (ultra-light)
Weight: 1.36 kg for 100 links
Relative lifespan: index 450 for 100 links
Recommended use: Cross, competition, and intensive training
Manufacturer reference: not provided

This kit combines the abrasion and traction resistance of a 520 chain with a lightweight aluminum sprocket, designed to minimize added mass on the rear axle. Suitable for many motocross bikes (e.g., Yamaha YZ 125 1993) after verifying the number of links and tension adjustment. Maintain regular upkeep (tension, cleaning, and proper lubrication) to preserve the performance and longevity of the kit.
