Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Yzf R1 04 is likely to perform.
Motorcycle lighting and signalling — 8.8% of failures
Motorcycle lighting and signalling issues account for 8.8% of MOT failures on the Yamaha Yzf R1 04. Motorcycle lighting and signalling issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
Motorcycle lamps and reflectors — 4.8% of failures
Motorcycle lamps and reflectors issues account for 4.8% of MOT failures on the Yamaha Yzf R1 04. 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 and wheels — 3.6% of failures
Motorcycle tyres and wheels issues account for 3.6% of MOT failures on the Yamaha Yzf R1 04. 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.
