From $16.30

Sprockets set your gearing. One tooth fewer at the front, or a couple more at the rear, makes the bike pull harder out of corners and lifts the front sooner, at the cost of top speed and higher revs on the highway. Going the other way calms it down. Worn sprockets have hooked or pointed teeth and will wear out a new chain quickly.

Fits 6 Yamaha models: see the list below

  • Computer-designed to achieve ultimate strength at minimum weight
  • Sprockets are heat-treated and bead-blasted to reduce material surface tension
  • Front sprockets are made with C45 steel and SCM415 chromoly steel alloy
  • Model-specific: check the fitment list for your bike

Changing tooth counts changes your speedometer reading on most bikes, and may need a different chain length. Replace sprockets and chain together.
