Motorcycle wheels — 1.0% of failures
Motorcycle wheels issues account for 1.0% of MOT failures on 1978 Honda Cbx models.

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 tyres — 1.0% of failures
Motorcycle tyres issues account for 1.0% of MOT failures on 1978 Honda Cbx 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.
