Should I check the MOT history before buying a 2020 Ajs Highway Star?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2020 Ajs Highway Star?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2020 Ajs Highway Star?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2020 Ajs Highway Star reliable?

Based on MOT data from 111 vehicles, the 2020 Ajs Highway Star has a first-time MOT pass rate of 82.7%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2020 Ajs Highway Star?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2020 AJS Highway Star is underperforming on its first MOT compared to the UK average, with a 62.4% pass rate against the national 80%—a meaningful gap that suggests common early issues. The good news is that only 8.1% of vehicles have recorded a dangerous defect, so safety failures are rare, but roughly four in ten examples are still encountering problems at their first test.

With a median mileage of just 2,857 miles, these bikes are relatively lightly used for their age, which makes the high failure rate more concerning—it points to design or build quality issues rather than wear and tear. The average vehicle racks up 0.47 failures and 1.2 advisories, typically minor matters like lights or corrosion, but if you're considering one, insist on a pre-purchase inspection covering the electrical system and have a mechanic familiar with AJS models check the bike over before committing.

We have limited data for the 2020 Ajs Highway Star — treat the figures below as indicative rather than definitive.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
