Should I check the MOT history before buying a 2018 Triumph Street?

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 2018 Triumph Street?

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.

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.

The 2018 Triumph Street is a genuinely reliable performer, passing MOT on first attempt 93.3% of the time—well ahead of the UK average of 80%. Dangerous defects are rare at 7.2%, so safety isn't a concern here.

These bikes are covered sparingly; the median mileage of just 6,462 miles suggests most owners treat them as weekend or leisure machines rather than daily workhorses. Failures average 0.38 per vehicle and advisories just 1.3, which is excellent—but before buying, ask the seller for full service history to confirm the bike has actually been maintained despite light use, because neglect on lightly-ridden bikes can hide problems.

The 2018 Triumph Street passes its MOT first time more often than most UK vehicles (93.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ 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.

For context

✅ Good baseline reliability. A 93.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,894 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
