About This Data
The 1988 Yamaha Dt125 has an MOT pass rate of 64.3% based on 409 tests — around the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 20,704 miles on the odometer. With a 35.7% failure rate, the 1988 Dt125 is rated as "Average" for MOT reliability.
If you own or are considering buying a 1988 Yamaha Dt125, budget for potential repairs before each MOT. Before your MOT, pay particular attention to motorcycle tyres: 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. With relatively low average mileage of 20,704 miles, many of these vehicles are still in good mechanical condition.
Motorcycle tyres — 1.5% of failures
Motorcycle tyres issues account for 1.5% of MOT failures on 1988 Yamaha Dt125 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.
Motorcycle wheels — 1.5% of failures
Motorcycle wheels issues account for 1.5% of MOT failures on 1988 Yamaha Dt125 models. Wheel failures include cracked or severely corroded alloy wheels, missing or loose wheel nuts, and wheels that are insecurely attached. These are safety-critical and relatively rare compared to tyre failures. Typical repair costs: £100–400 per wheel. Pre-MOT check: Visually inspect wheels for cracks, especially around the spokes and rim. Check that all wheel nuts are present and tightened. Look for signs of impact damage on alloy wheels.
Motorcycle brakes — 0.2% of failures
Motorcycle brakes issues account for 0.2% of MOT failures on 1988 Yamaha Dt125 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).
