Motorcycle Vehicle Knowledge and Maintenance
This domain checks whether you know your machine and can spot a fault before it becomes a crash. Questions cover pre-ride checks, legally required equipment, and simple maintenance.
Pre-ride check
Use a quick T-CLOCS routine:
- Tires: correct pressure, legal tread, no cuts or bulges.
- Controls: throttle returns freely, clutch and brake levers firm, cables not frayed.
- Lights: headlight, tail light, brake light and turn signals working.
- Oil and fuel: no leaks, correct levels.
- Chain: cleaned, lubricated and at the slack stated in the owner's manual - typically about 20–30 mm.
- Stands, brakes, mirrors and horn.
Legal equipment
Philippine rules require two mirrors, a working horn, front and rear brakes, lights, a proper muffler and a visible plate. Open or excessively loud exhausts violate LTO modification and anti-noise rules. Carry the OR/CR and a valid CTPL insurance certificate.
Maintenance
Check tyre pressure weekly; lubricate the chain every 500 km or after rain; replace brake pads before the lining is gone; check battery terminals; follow the manual's oil interval.
Worked example
A chain with 10 mm of slack feels tight and whines. Too tight loads the countershaft bearing and can snap; too loose can jump the sprocket. The manual specifies 20–30 mm, so you adjust to that and recheck alignment.
Traps
Relying only on the rear brake because the front feels dangerous; overinflating tyres for fuel economy; fitting a loud pipe; assuming a tyre with visible tread is safe when it is cracked or old.
