EK/PBR 520SRX2 Chain Kit 14/48 - ultra-light sprocket by EK CHAIN: a kit designed for motocross riders seeking a reliable and lightweight transmission for their off-road adventures. This 520SRX2 kit combines a robust chain with a 520 pitch and an ultra-light aluminum rear sprocket, optimized to reduce unsprung weight without compromising performance in enduro/cross use.
- Configuration: 14-tooth sprocket / 48-tooth sprocket
- Number of links: 116
- Pitch: 520
- Chain color: steel/steel
- Sprocket material: aluminum (ultra-light)
- Weight: 1.54 kg for 100 links

Designed to fit notably the KTM 300 EGS models (1997–1999), this kit provides the standard components to replace your final drive: sprocket, chain, and rear sprocket. The aluminum sprocket reduces inertia and facilitates acceleration on varied terrain, while the SRX2 chain offers a balance between strength and weight/longevity ratio.
Before installation, check the precise compatibility with your model, the sprocket/chain alignment, and the chain tension. Regular maintenance (cleaning, lubrication, and slack checking) will preserve the longevity of the kit and ensure smooth and safe transmission during your motocross sessions.
