PBR Standard Steel Sprocket 239 - 420 (Manufacturer Part No: 239 45 F)
Designed by PBR, a brand rooted in competition, this standard steel sprocket is aimed at urban riders seeking a reliable and robust transmission. Its construction from 18NCD5 steel alloy ensures mechanical durability suitable for daily use, and its black finish integrates discreetly with the bike's components.
- Type: Standard for 420 chain transmission
- Material: Steel (18NCD5 alloy)
- Number of teeth: 45
- Color: Black
- Manufacturer Part No: 239 45 F
The PBR manufacturing process, inspired by competitive experience, aims to ensure precision-cut teeth for smooth interaction with the pinion and chain. The sprocket offers good resistance to corrosion and abrasion, and its machining helps to minimize friction within the transmission.
Compatible with rear setups using the 420 pitch and perfectly suited for the machines listed in the reference (including the HONDA MTX 80 RS, MTX 80 RF, and MTX 80), this sprocket is a relevant choice for the maintenance or restoration of an urban motorcycle. Installation is done by directly replacing the original components.
