If you own or are considering buying a 1988 Yamaha Dt, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle wheels: 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. With relatively low average mileage of 17,531 miles, many of these vehicles are still in good mechanical condition.
Motorcycle wheels — 4.0% of failures
Motorcycle wheels issues account for 4.0% of MOT failures on 1988 Yamaha Dt 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 — 4.0% of failures
Motorcycle brakes issues account for 4.0% of MOT failures on 1988 Yamaha Dt 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 tyres — 4.0% of failures
Motorcycle tyres issues account for 4.0% of MOT failures on 1988 Yamaha Dt 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.
