The RK Steel Rear Sprocket is a direct-replacement rear sprocket for the Honda Grom (2022 and later), designed for riders looking to restore worn drivetrain components or carry out a sprocket-and-chain service.

Manufactured by RK, a brand with a long history in motorcycle chain and sprocket production, this sprocket is machined to a 37-tooth, 428-pitch specification to suit the Grom's factory drivetrain layout.

  • 428 pitch — matches the Grom's factory chain specification
  • Steel construction for durability
  • Direct OEM-style fitment, no modification required

  • Always replace the rear sprocket together with the front sprocket and chain — mixing worn and new components accelerates wear on all three.
  • Before fitting, clean the sprocket carrier/hub of any debris, corrosion or old gasket material to ensure a flat seating surface.
  • Torque the sprocket mounting bolts to the specification listed in the Honda Grom service manual; do not rely on feel alone.
  • After installation, check and set chain slack to the manufacturer's recommended free-play before riding.
  • Lubricate the chain regularly using a motorcycle-specific chain lubricant; this also reduces wear on the sprocket teeth.
  • Inspect the sprocket teeth periodically for hooked, shark-finned or visibly worn profiles — these indicate the sprocket requires replacement.
  • Avoid pressure-washing directly at the sprocket and chain; if washing the bike, re-lubricate the chain afterwards.
  • Store the sprocket in a dry environment if not fitting immediately; light application of a corrosion inhibitor will protect the steel surface during extended storage.
