Vespa 150s MOT Reliability Overview
The Vespa 150s is a rare vehicle in the UK, with 82 MOT test results recorded in our database spanning 1 manufacture years. It has an overall MOT pass rate of 95.1% and a failure rate of 4.9%, which is well above the UK average of approximately 37%.
Based on this data, the Vespa 150s earns a "Excellent" reliability rating. The average Vespa 150s presents for MOT with approximately 16,518 miles on the clock. The 1965 manufacture year performs best with a 90.7% pass rate.
The most common MOT failure for the Vespa 150s is Motorcycle steering and suspension, affecting 2.4% of all tests. 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. The second most common issue is Motorcycle lighting and signalling at 2.4%. Motorcycle brakes rounds out the top three at 1.2%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

For Vespa 150s owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on motorcycle steering and suspension and motorcycle lighting and signalling 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 150s is likely to perform.
Motorcycle steering and suspension — 2.4% of failures
Motorcycle steering and suspension issues account for 2.4% of MOT failures on the Vespa 150s. 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.
Motorcycle lighting and signalling — 2.4% of failures
Motorcycle lighting and signalling issues account for 2.4% of MOT failures on the Vespa 150s. 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 brakes — 1.2% of failures
Motorcycle brakes issues account for 1.2% of MOT failures on the Vespa 150s. 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).
