PBR Twin Color Aluminium Ultra-Light Self-Cleaning Hard Anodized 489 - 520 SprocketRef : PBR01029A / 1096611005

PBR Twin Color Crown ultra-light hard anodized mud-resistant aluminum 489 - 520 (Manufacturer part number: 489 52 TC7): a crown designed for Cross, MX, and Enduro riders seeking lightweight and reliability on muddy terrains.

• Material: Precision machined 7075 T6 aluminum
• Chain compatibility: Pitch 520 — 52 teeth
• Finish: Bi-color hard anodization (Black/Green) for surface resistance and race look
• Design: Mud-resistant tooth profile and strategic cutouts to reduce weight without sacrificing strength

The tooth geometry facilitates mud evacuation and limits chain snags in muddy specials. The machined cutouts reduce rotating mass while maintaining the necessary rigidity for terrain demands. The hardened anodization provides surface protection against impacts and abrasion while highlighting the twin color look, highly appreciated on a cross or SX bike.

Practical for competition or training, this PBR crown fits the demanding models listed in the compatibilities (e.g., KAWASAKI KX 450, SUZUKI RM-Z 250). A technical and aesthetic choice for those who want to lighten their transmission without compromising performance in extreme conditions.
