Designed by PBR from its racing expertise, the Ultra-Light hard anodized sprocket 4647 is a transmission part dedicated to demanding roadsters. Its aluminum construction combines lightweight and strength: the hard anodization protects the surface against corrosion and abrasion while the lightweight design minimizes the mass of the rear wheel.

• Material: hard anodized aluminum (stainless finish)
• Number of teeth: 45
• Chain pitch: 520
• Type: standard, suitable for final drive
• Manufacturing: strict quality control process for consistent tooth profile

Ideal for replacing the original sprocket on compatible machines, it retains the classic specifications to fit directly with 520 chain systems. Its tooth profile and material quality aim to ensure consistent contact with the pinion and controlled wear over time.

Known compatibilities: including BMW S 1000 RR (2013-2014). Always check compatibility with your model and reference before installation.
