EK / PBR 520SRX2 Chain Kit – Royal Enfield 350
Classic 350 / Meteor 350 / HNTR 350 / Bullet 350

This chain kit combines EK Chain, a Japanese manufacturer globally recognized for the quality and reliability of its drive chains, and PBR, a European specialist in precisely machined steel sprockets and crowns. It is an ideal replacement solution for the original parts on Royal Enfield 350 single-cylinder motorcycles, offering an excellent balance between performance, durability, and cost control.

Recommended option – EK SLJ screw-on quick link
Don’t have a crimping tool? The EK SLJ quick link is the perfect solution. It allows for simple and secure installation without special tools, while providing a fastening equivalent to a rivet once tightened. More reliable than a clip link, it ensures safe and durable power transmission. A practical and reassuring option to confidently install your chain kit.

The EK SRX2 series is known for its optimal balance between strength and flexibility. Although long established in the EK range, it benefits from regular updates incorporating modern technologies to improve durability and smooth operation.

The EK 520SRX2 QX-Ring chain is a crimped chain, ensuring a permanent link fastening. Crimping provides significantly greater security than a clip link, minimizes the risk of accidental opening, and is especially recommended for daily road use, mixed riding, or two-up riding.

The QX-Ring technology retains internal lubrication, reduces friction, and ensures even wear while maintaining smooth and quiet power transmission.

The PBR C45 steel sprocket and crown provide precise and consistent engagement, excellent wear resistance, and longevity that meets the requirements of the original transmission.
