T-CLOCK Inspection Worksheet:

T-CLOCK is a mnemonic developed by the Motorcycle Safety Foundation for assisting you in doing a comprehensive pre-ride (or a pre-purchase) inspection of a motorcycle. It is easily memorized and very useful. The individual letters stand for the specific areas to check:
  • T — Tires & Wheels
  • C — Controls
  • L — Lights
  • O — Oil
  • C — Chassis
  • K — Kickstand

Just print these pages and stick them on the wall near where you store your mototcycle(s), or stuff them in your tank bag or under the seat...
