If you own or are considering buying a 1991 Honda Cb-1, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle suspension: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks. With relatively low average mileage of 49,051 miles, many of these vehicles are still in good mechanical condition.
Motorcycle suspension — 2.9% of failures
Motorcycle suspension issues account for 2.9% of MOT failures on 1991 Honda Cb-1 models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Motorcycle lamps and reflectors — 1.5% of failures
Motorcycle lamps and reflectors issues account for 1.5% of MOT failures on 1991 Honda Cb-1 models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. 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.
Motorcycle steering — 1.5% of failures
Motorcycle steering issues account for 1.5% of MOT failures on 1991 Honda Cb-1 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.
