If you own or are considering buying a 2019 Ajs Firefox, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle lamps and reflectors: 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. With relatively low average mileage of 5,523 miles, many of these vehicles are still in good mechanical condition.
Motorcycle lamps and reflectors — 8.0% of failures
Motorcycle lamps and reflectors issues account for 8.0% of MOT failures on 2019 Ajs Firefox 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 suspension — 4.4% of failures
Motorcycle suspension issues account for 4.4% of MOT failures on 2019 Ajs Firefox 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 brakes — 2.9% of failures
Motorcycle brakes issues account for 2.9% of MOT failures on 2019 Ajs Firefox models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
