Honda Sh300i MOT Reliability Overview
The Honda Sh300i is a rare vehicle in the UK, with 550 MOT test results recorded in our database spanning 5 manufacture years. It has an overall MOT pass rate of 81.5% and a failure rate of 18.5%, which is well above the UK average of approximately 37%.
Based on this data, the Honda Sh300i earns a "Excellent" reliability rating. The average Honda Sh300i presents for MOT with approximately 17,146 miles on the clock. Manufacture year matters: 2011 models achieve the highest pass rate at 93.3%, while 2009 models have the lowest at 72.9%. This 20.4 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Honda Sh300i is Motorcycle brakes, affecting 15.3% of all tests. 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. The second most common issue is Motorcycle lighting and signalling at 6.4%. Motorcycle tyres and wheels rounds out the top three at 5.6%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Sh300i is likely to perform.
Motorcycle brakes — 15.3% of failures
Motorcycle brakes issues account for 15.3% of MOT failures on the Honda Sh300i. 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 lighting and signalling — 6.4% of failures
Motorcycle lighting and signalling issues account for 6.4% of MOT failures on the Honda Sh300i. 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 — 5.6% of failures
Motorcycle tyres and wheels issues account for 5.6% of MOT failures on the Honda Sh300i. 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.
