PBR Standard Steel Sprocket 2273 - 520 (Manufacturer Ref: 2273 14 18NC)
Designed by PBR, a brand born from competition, this 2273 steel sprocket is aimed at riders concerned with the reliability of their transmission. Intended for the roadster segment, it features an 18NCD5 steel alloy known for its manufacturing quality and wear resistance.
The very strict production process and surface treatment provide the sprocket with good resistance to corrosion and abrasion, extending its lifespan against the daily stresses of a transmission (chain, crown). Designed to replace an original 14-tooth sprocket with a 520 pitch, it easily integrates into compatible drivetrains while maintaining the original gear ratio settings.
Ideal for road riders and mechanical enthusiasts, this sprocket is a simple and reliable choice for maintaining the heart of your transmission. Examples of compatible models among the most common include: KAWASAKI NINJA ZX-4RR (2025), KAWASAKI NINJA ZX-4R (2025), KAWASAKI Z 400 (2024).
