If you own or are considering buying a 2021 Sym Jet X 125 E5, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle brakes: 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). With relatively low average mileage of 10,697 miles, many of these vehicles are still in good mechanical condition.
Motorcycle brakes — 23.4% of failures
Motorcycle brakes issues account for 23.4% of MOT failures on 2021 Sym Jet X 125 E5 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).
Motorcycle lamps and reflectors — 11.7% of failures
Motorcycle lamps and reflectors issues account for 11.7% of MOT failures on 2021 Sym Jet X 125 E5 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 tyres — 9.1% of failures
Motorcycle tyres issues account for 9.1% of MOT failures on 2021 Sym Jet X 125 E5 models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
