If you own or are considering buying a 1986 Yamaha T80, 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 18,970 miles, many of these vehicles are still in good mechanical condition.
Motorcycle wheels — 4.4% of failures
Motorcycle wheels issues account for 4.4% of MOT failures on 1986 Yamaha T80 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 lamps and reflectors — 3.0% of failures
Motorcycle lamps and reflectors issues account for 3.0% of MOT failures on 1986 Yamaha T80 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 brakes — 1.5% of failures
Motorcycle brakes issues account for 1.5% of MOT failures on 1986 Yamaha T80 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).
