Norton Model 19 MOT failure rate

What a Norton Model 19 fails its MOT on, and the part that fixes each.

What it fails on, and why

Tyres50.0% of failures

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.

Other50.0% of failures

This covers a range of smaller items, from a non-working horn to a warning light left on.

Steering50.0% of failures

Steering faults are typically worn track-rod ends or ball joints, play in the rack, or a split gaiter letting grease out and dirt in. Excessive free play at the wheel fails.

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. Confirm the exact fitment against your registration or VIN before buying.
