The EK CHAIN 520SRX2 13/50 chain kit is a complete set designed for motocross use, offering the performance/price compromise that has made the SRX series renowned. It is ideal for those looking to replace the chain, sprocket, and rear wheel gear while maintaining a lightweight setup and a polished aesthetic.
- Configuration: 13 teeth (sprocket) / 50 teeth (rear gear) — ultra-light aluminum rear gear
- Chain: pitch 520, 114 links, Gold/Gold finish
- Relative lifespan: index 3300 (for 100 links)
- Weight: 1.54 kg per 100 links (manufacturer reference)
The aluminum rear gear reduces the unsprung weight, which is an advantage in technical sections and jumps. The golden color adds a racing look that particularly complements motocross machines. With 114 links and a 520 pitch, the kit fits the standard setups of enduro/motocross bikes designed for this ratio.
Compatibility (examples): KTM 360 EXC 1996 / 1997. Manufacturer reference: not disclosed.
Usage advice: regularly check the tension, lubricate after washing, and replace the kit as a whole to maintain transmission reliability. This EK SRX2 kit is aimed at motocross riders who want a proven, lightweight part with a refined visual appeal.
