Motorcycle lamps and reflectors — 6.3% of failures
Motorcycle lamps and reflectors issues account for 6.3% of MOT failures on the Harley-davidson Fls 103 Softail Slim 14. 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 tyres — 6.3% of failures
Motorcycle tyres issues account for 6.3% of MOT failures on the Harley-davidson Fls 103 Softail Slim 14. 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.
Identification of the vehicle — 3.1% of failures
Identification of the vehicle issues account for 3.1% of MOT failures on the Harley-davidson Fls 103 Softail Slim 14. Identification failures relate to the Vehicle Identification Number (VIN) and registration plate. The VIN must be permanently displayed and legible, and the registration plate must meet British Standard formatting. Typical repair costs: £10–50. Pre-MOT check: Ensure the VIN plate is visible and legible (usually in the windscreen or under the bonnet). Check that number plates are clean, undamaged, and use the correct font and spacing.
