Should I check the MOT history before buying a 2017 Triumph S?

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 2017 Triumph S?

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 2017 Triumph S?

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.

Do I need an HPI check when buying a 2017 Triumph S?

The 2017 Triumph S is a notably reliable choice, with a first-time pass rate of 94.1%—well above the UK average of 80%—and only 6.2% of vehicles ever flagged for dangerous defects, which is reassuringly low. This suggests strong build quality and consistent durability across the cohort.

These motorcycles are running at sensible mileages for their age, with a median of 7,467 miles, and they're not throwing up serious problems: the average vehicle has just 0.41 failures per test but 2.1 advisories, meaning minor wear items rather than structural concerns. If you're considering one, a pre-purchase inspection should focus on those advisory items—typically consumables like brake pads or chain wear—rather than hunting for hidden faults.

We have limited data for the 2017 Triumph S — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 20 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.

Across 290 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Exhaust & emissions 41.5%

Exhaust noisy

Tyre wear 31.9%
