PBR Standard Steel Sprocket 347M - 520: a transmission component designed to replace the original sprocket on drivetrains equipped with a 520 pitch chain. Manufactured by PBR, an Italian manufacturer renowned for its transmission components, this sprocket benefits from expertise developed partly through collaboration with racing teams.

• Material: Steel
• Type: 347M, standard version
• Number of teeth: 14 teeth
• Chain pitch: 520
• Manufacturer reference: 347M 14 18NC

The steel construction ensures mechanical durability suitable for road and recreational use, while the 14-tooth geometry directly influences the gearing: compared to a sprocket with more teeth, it tends towards a shorter gearing ratio, noticeable in engine response. Designed as a standard replacement part, it installs on compatible 520 transmissions following the installation guidelines.

Recommended use: Roadster. Examples of frequently associated models: HONDA CB 750 HORNET (2025), HONDA XL 750 TRANSALP (2024), HONDA CBR 650 R (2024). Check the number of teeth and chain pitch of your setup before ordering to ensure compatibility.
