Norton Roadster MOT failure rate
What a Norton Roadster fails its MOT on, from real DVSA test data, and the part that resolves each item.
Based on 98 MOT tests in DVSA data.
We hold 98 MOT tests for the Norton Roadster in the DVSA data. That is a smaller sample than our high-volume models, so treat these figures as indicative rather than definitive.
On what we have, about 7.1% fail, most often on tyres, brakes. For a precise picture of your own car, use the registration check on the home page. Confirm any part against your registration or VIN before buying.
What it fails on, and why
Tyres fail for tread below the 1.6mm legal limit across the central three-quarters, uneven or exposed-cord wear, or sidewall damage. The tester inspects all four; a single illegal tyre is a fail.
Brake failures cover worn pads and discs, an imbalance between wheels, corroded or scored discs, or a binding caliper. Braking efficiency is measured on a rolling road, so a spongy or pulling brake shows up as a low reading.
The parts that fix each
If your car has just failed, you have 10 working days to fix the items and get a free partial retest. These are the usual parts; confirm the exact fitment against your registration or VIN before buying.
