The EK CHAIN 520SROZ2 14/45 chain kit — standard sprocket is a set designed for roadsters seeking a robust and easy-to-maintain transmission. Coming from the SRO series, this O-ring chain offers a good balance between cost and longevity, while maintaining the manufacturing quality characteristic of EK.

• Type: 520SROZ2 chain kit with 14-tooth sprocket / 45-tooth standard sprocket
• Number of links: 112
• Pitch: 520
• Sprocket material: Steel
• Color: Steel / Steel
• Relative lifespan: 2400 (manufacturer's value for 100 links)

The chain features a reduced drilling that decreases mass and thermally treated steel alloys, characteristics that contribute to its strength. The O-rings protect the rollers and reduce dirt penetration, helping to preserve the longevity of the drive train.

Usage tips: regularly check the tension, lubricate as recommended, and replace the complete kit when significant wear occurs to avoid damaging the sprocket and crown. Compatible with many roadsters — notably including the KTM 125 DUKE ABS (2023–2025) among frequently mounted models.
