How to Do a Pre-Ride Motorcycle Inspection (T-CLOCS, Plain English)
The T-CLOCS pre-ride inspection is the standard recommended by the Motorcycle Safety Foundation. It covers the six areas that are most likely to fail on a motorcycle and cause a crash or a breakdown. Done right, it takes about five minutes. Done consistently, it’s one of the most effective safety habits a rider can build.
Here’s the full rundown — what each letter means, what you’re actually checking, and what a problem looks like.
T — Tires and Wheels
Tires are the only contact point between you and the road. They deserve first position.
What to check:
- Pressure. Cold tire pressure should match the spec on your bike’s placard or in the owner’s manual — not the max pressure printed on the tire sidewall. Low pressure affects handling and heat management. High pressure reduces contact patch and grip.
- Tread depth. The legal minimum is 2/32″ but you should be looking at replacement before you get there. Most sport and street tires start degrading grip noticeably before the wear indicators. Get a tread depth gauge and know your actual numbers.
- Condition. Look for cracking, bubbles, embedded objects, or uneven wear. Side-to-side wear differences can indicate alignment or suspension issues.
- Wheels. Check for loose or broken spokes (on wire wheels), rim damage, and that axle nuts are secure.
C — Controls
Controls is everything you touch while riding: levers, pedals, throttle, cables.
What to check:
- Lever feel. Brake levers should be firm, not spongy. Spongy feel = air in the brake system. Front brake should engage smoothly with consistent pressure. Clutch lever should have the right amount of freeplay per your manual (typically 2–3mm).
- Throttle. Open and close it — it should snap back completely when released. With bars at full lock both directions, there should be no binding, sticking, or delayed return.
- Cables. Look for kinks, fraying at the ends, or routing that could bind when the bars turn.
- Brake pedal. Press it — it should be firm and not travel to the floorboard.
L — Lights and Electrics
A few seconds to confirm your lights are working is a lot faster than explaining to a cop why your brake light was out.
What to check:
- Headlight (both low and high beam)
- Brake light (activate with both front lever and rear pedal — they should both trigger it)
- Turn signals (all four — front and rear, left and right)
- Instruments: speedo, fuel gauge, warning lights. If a warning light is on, don’t ignore it hoping it’ll go away.
- Horn. Takes one second. You’ll be glad it works when you need it.
O — Oil and Fluids
Quick visual check on fluid levels — not a full fluid analysis, just confirmation you’re not critically low.
What to check:
- Engine oil. Check the sight glass or dipstick. Should be within the marked range. Look under the bike for any fresh oil spots on the ground — drips on pavement mean something is seeping.
- Coolant. Coolant-cooled bikes have a reservoir with min/max marks. Takes three seconds to look.
- Brake fluid. Both master cylinders (front and rear) have inspection windows. Fluid should be at the marked level. Note: dark fluid = old fluid. Brake fluid absorbs moisture over time and should be replaced every 1–2 years regardless of level.
- Fuel. Know your actual fuel level. Reserve doesn’t mean you can skip this check.
C — Chassis
The chassis check covers everything structural and mechanical — the parts that keep the bike together.
What to check:
- Chain or belt. Check tension and lubrication. A dry chain is a chain in the process of wearing out. Adjust tension per your manual if it’s too loose or too tight.
- Suspension. Push down on the front forks and release — it should rebound smoothly without bottoming or sticking. Check for fork seal leaks (oil residue on the lower legs).
- Frame and swingarm. Look for cracks, bends, or anything that wasn’t there before. After any drop or impact, inspect the frame carefully.
- Fasteners. You can’t torque-check everything in a pre-ride, but look for anything obviously loose: handlebars, mirrors, levers, pegs.
S — Sidestand
The sidestand check is quick but specific: confirm the stand retracts fully and that the sidestand switch is working.
What to check:
- Sidestand retracts when you lift it — spring tension intact, not broken
- Most modern bikes cut the engine if you try to ride away with the stand down. Test that the safety switch works: put the bike in gear with the stand down — it should stall or not start
- Look at the base of the stand for cracks, especially if you’ve had any drops
Make It a Logged Habit
The T-CLOCS inspection is most useful when it’s consistent. A one-time thorough inspection tells you where the bike is right now. A logged history of inspections tells you where it’s going — and catches trends before they become failures.
Moto Frontier’s Ride Check walks you through a guided T-CLOCS-style inspection tied to each bike in your garage. Every check is logged with a Ride Health Score, and you can add photos to any item that needs monitoring. Over time, you build a real inspection history — not a vague sense that “the bike feels fine.”
