With relatively low average mileage of 11,307 miles, many of these vehicles are still in good mechanical condition.
Motorcycle body and structure — 2.4% of failures
Motorcycle body and structure issues account for 2.4% of MOT failures on 1973 Honda Cb450 models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
Motorcycle lighting and signalling — 2.4% of failures
Motorcycle lighting and signalling issues account for 2.4% of MOT failures on 1973 Honda Cb450 models. 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 tyres and wheels — 2.4% of failures
Motorcycle tyres and wheels issues account for 2.4% of MOT failures on 1973 Honda Cb450 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.
