If you own or are considering buying a 1985 Harley Davidson Fxsb, you can expect reliable MOT performance overall. 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 24,171 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 1985 Harley Davidson Fxsb 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 lamps and reflectors — 1.5% of failures
Motorcycle lamps and reflectors issues account for 1.5% of MOT failures on 1985 Harley Davidson Fxsb 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 steering — 1.5% of failures
Motorcycle steering issues account for 1.5% of MOT failures on 1985 Harley Davidson Fxsb models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
