Triumph Street (2018)
2018 Triumph Street
CarHunch analysed 1,894 real MOT records for the 2018 Triumph Street. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
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.
What to check before buying a 2018 Triumph Street
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
