PBR Ultra-Light Hard Anodized Aluminum Sprocket 4586 - 520 (Manufacturer Part No: 4586 41 LD)

Designed by PBR with experience gained from competition, this ultra-light aluminum sprocket is aimed at riders who care about the quality of their final drive. Its hard anodized treatment offers enhanced protection against corrosion and abrasion while maintaining an elegant stainless steel finish.

• Material: hard anodized aluminum, resistant surface
• Number of teeth: 41
• Chain pitch: 520 (compatible with 520 chains)
• Type: standard, road/roadster use

The lightweight design helps to limit the unsprung mass of the wheel/transmission assembly, facilitating a more responsive behavior of the rear end without compromising the durability claimed by PBR. The precise tooth design and quality finishes contribute to reducing friction at the pinion-sprocket connection, resulting in a smoother chain engagement on a daily basis.

Notable compatibility: particularly suitable for BMW S 1000 RR ABS (2014, 2016, and 2018 models listed). Before installation, ensure compatibility with your pinion and registration document.

This product is intended for demanding users seeking a reliable, lightweight sprocket that is protected against wear for roadster use.
