If you own or are considering buying a 2003 Aprilia Sonic, 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 8,626 miles, many of these vehicles are still in good mechanical condition.
Motorcycle brakes — 2.2% of failures
Motorcycle brakes issues account for 2.2% of MOT failures on 2003 Aprilia Sonic 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 lighting and signalling — 2.2% of failures
Motorcycle lighting and signalling issues account for 2.2% of MOT failures on 2003 Aprilia Sonic models. Motorcycle lighting and signalling issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
Motorcycle tyres and wheels — 2.2% of failures
Motorcycle tyres and wheels issues account for 2.2% of MOT failures on 2003 Aprilia Sonic 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.
