Triumph Historic MOT failure rate

What a Triumph Historic fails its MOT on, and the part that fixes each.

What it fails on, and why

Tyres11.1% 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.

Other11.1% of failures

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

Brakes11.1% of failures

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