For Honda CBR400 NC29 Gullarm
40 tooth 520 pitch Renthal hard anodized gold alloy rear sprocket.
Renthal’s hard anodised rear chainwheels are specifically designed for road and road racing applications.
They are CNC machined from the same 7075 T6 material as their offroad chainwheels, yet feature the increased longevity from the hard anodizing process. Hard anodizing is an integral surface coating which significantly increases the hardness and wear resistance of the chainwheel surface.
