Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Roadster is likely to perform.
Motorcycle steering and suspension — 7.5% of failures
Motorcycle steering and suspension issues account for 7.5% of MOT failures on the Harley-davidson Roadster. 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 — 6.6% of failures
Motorcycle lighting and signalling issues account for 6.6% of MOT failures on the Harley-davidson Roadster. 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 — 4.7% of failures
Motorcycle brakes issues account for 4.7% of MOT failures on the Harley-davidson Roadster. 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).
