Motorcycle lamps and reflectors issues account for 0.6% of MOT failures on 1980 Triumph T140 models.

Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Identification of the vehicle — 0.4% of failures
Identification of the vehicle issues account for 0.4% of MOT failures on 1980 Triumph T140 models. Identification failures relate to the Vehicle Identification Number (VIN) and registration plate. The VIN must be permanently displayed and legible, and the registration plate must meet British Standard formatting. Typical repair costs: £10–50.

Motorcycle steering — 0.4% of failures
Motorcycle steering issues account for 0.4% of MOT failures on 1980 Triumph T140 models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
