Tools

• Center lift.
• 27mm socket for the rear axle nut.

  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.

Prerequisites

1. Remove the rear wheel.
2. Remove the swingarm.

Recommendations

• 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.

Steps

• Disclaimer:

  TBD, but the OEM should supply instructions
