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...

T — TIRES & WHEELS
Item	Check	Look for	Check off
Tires	Condition	Tread depth, wear, weathering, evenly seated, bulges, imbedded objects.	Front - Rear
	Air Pressure	Check when cold, adjust to load/speed.	Front - Rear
Wheels	Spokes	Bent, broken, missing, tension, check at top of wheel: "ring" == OK, "thud" == loose spoke.	Front - Rear
	Cast	Cracks, dents.	Front - Rear
	Rims	Out of round/true == 5mm. Spin wheel, index against a stationary pointer.	Front - Rear
	Bearings	Grab top and bottom of tire and flex: No freeplay (click) between hub and axle, no growl when spinning	Front - Rear
	Seals	Cracked, cut or torn, excessive grease on outside, reddish-brown outside.	Front - Rear

C — CONTROLS
