The EK/PBR 520SRX2 15/45 chain kit combines a 520 SRX series chain with a hardened Ergal sprocket to provide a complete and reliable setup for roadsters and small sportbikes. The SRX series is known for its good balance between durability and cost, adopted by many riders seeking a reliable transmission for daily use.
- Composition: steel/steel chain, 112 links, pitch 520.
- Sprocket / crown: 15 teeth / 45 teeth, hardened Ergal crown (treated aluminum).
- Weight: 1.54 kg for 100 links (manufacturer reference).
- Longevity index: relative value 3300 (for 100 links).
Designed to replace the original drive element, this kit is particularly suitable for small displacement machines such as the KTM 390 DUKE ABS (2024), KTM RC 390 ABS (2021), and KTM RC 390 R (2018). The hardened Ergal crown minimizes wear while remaining lightweight, and the 520 pitch ensures common compatibility with sprocket/crown sets intended for roadsters.
Before installation, check the alignment, tension, and condition of the primary sprocket. Regular lubrication and adjustment will extend the longevity of the transmission. Manufacturer reference: not provided.
