Video Guide
  • Center lift.
  • 27mm socket for the rear axle nut.
  • 3mm Allen key.
  • 10mm Allen key socket
    Ensure at least 1" depth and a ⅜" drive sufficient to handle swingarm pivot bolt torques.
  • 15mm socket wrench (S models).
  • 13mm socket wrench (X models).
  • Torque wrench capable of setting 75ft-lbs and driving the 27mm socket and 10mm Allen key.
  • 2012-2013:
    • 2.5mm Allen key.
    • 24mm socket wrench.
  • (2013-2017?) 6mm Allen key and wrench to remove the rear sprocket pulley from the rear wheel.
  • (2018?) T45 Torx bit and wrench to remove the rear sprocket pulley from the rear wheel.
  1. Remove the rear wheel.
  2. Remove the swingarm.
  • For any chain fitment, wait until running the chain over the sprockets (and probably through the guide) before unlinking the chain and fitting a master link for its final length.
    Any mistakes in length estimation require more chain tool use which is just adding risk.
