If you own or are considering buying a 1978 Honda Nc50, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle tyres and wheels: 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 3,731 miles, many of these vehicles are still in good mechanical condition.

Motorcycle tyres and wheels issues account for 5.3% of MOT failures on 1978 Honda Nc50 models.

Motorcycle steering and suspension — 2.6% of failures
Motorcycle steering and suspension issues account for 2.6% of MOT failures on 1978 Honda Nc50 models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
