About This Product
When you are working on the early 5-speed Sportsters, having a precision-cut sprocket is vital for smooth operation and longevity. This 21-tooth PBI transmission sprocket is CNC machined in the USA from 8620 alloy steel, then heat-treated and nickel-plated for a tough, wear-resistant finish. It is designed specifically to fit 1991 to 1992 5-speed XL Sportster models and serves as a direct replacement for OEM 37709-89. The high-grade materials and exacting manufacturing process ensure it can handle the stresses of daily riding while maintaining perfect chain alignment. It is an excellent choice for riders who demand American-made quality and factory-spec fitment for their drivetrain.
Manufacturer part number: 277-21.
