PBR Standard Steel Sprocket 4406 - 420 (Manufacturer's Ref: 4406 50 F)
Designed for urban rides as well as spirited performance on light trails, this PBR sprocket is aimed at demanding riders who want a robust and reliable drive component. Machined from 18NCD5 steel alloy, it offers a combination of mechanical strength and wear resistance suited to the daily demands of the transmission.
The sprocket is treated to resist corrosion and abrasion, and its profile minimizes friction against the chain, promoting smooth transmission. An ideal replacement part during maintenance or when changing gearing, it fits 420 setups and is particularly suitable for the following 50cc models: DERBI SENDA X-TREME 50 R (2022), APRILIA RX 50 (2018), and DERBI SENDA 50 SM DRD X-TREM (2016).
Easy to install for a mechanic or in a workshop, this PBR sprocket allows for a healthy and secure transmission without compromising on material quality.
