About This Product
MCS 25-tooth motor sprocket for the primary drive. Fits 1930 to 1954 Big Twins with a tapered sprocket shaft. Replaces OEM 40212-30 and 519441. Precision-cut teeth give smooth chain engagement and long-wearing durability for the high-torque demands of these classic engines. Use it for period-correct restorations or to keep your Panhead or Knucklehead on the road. It fits early tapered shaft assemblies reliably.
Manufacturer part number: 519441.
