Honda C90-n MOT Reliability Overview
The Honda C90-n is a rare vehicle in the UK, with 191 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 82.7% and a failure rate of 17.3%, which is well above the UK average of approximately 37%.
Based on this data, the Honda C90-n earns a "Excellent" reliability rating. The average Honda C90-n presents for MOT with approximately 19,005 miles on the clock. Manufacture year matters: 1992 models achieve the highest pass rate at 88.9%, while 1993 models have the lowest at 79.6%. This 9.3 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Honda C90-n is Motorcycle tyres and wheels, affecting 7.9% of all tests. 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. The second most common issue is Motorcycle brakes at 7.3%. Motorcycle steering and suspension rounds out the top three at 5.2%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

Focus your pre-MOT checks on motorcycle tyres and wheels and motorcycle brakes for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific C90-n is likely to perform.
Motorcycle tyres and wheels — 7.9% of failures
Motorcycle tyres and wheels issues account for 7.9% of MOT failures on the Honda C90-n. 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.
Motorcycle brakes — 7.3% of failures
Motorcycle brakes issues account for 7.3% of MOT failures on the Honda C90-n. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Motorcycle steering and suspension — 5.2% of failures
Motorcycle steering and suspension issues account for 5.2% of MOT failures on the Honda C90-n. 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.
