JT JTR487.42 42-Tooth Steel Rear Sprocket

The JT JTR487.42 steel rear sprocket pairs a 42-tooth profile with 520-chain compatibility for a durable motorcycle drivetrain replacement. Made from Japanese 545C high-carbon steel, it offers wear resistance at an economical price.

Features

  • Japanese 545C high-carbon steel construction for strength and durability.
  • Heat treated and hand finished to meet or exceed OEM standards.
  • Designed for consistent fit, smooth operation and reliable power transfer.
  • JT states that its high-carbon steel sprockets outlast mild-steel or surface-hardened sprockets by two to three times.
