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

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 Thunderbird?

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 Thunderbird?

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 2017 Triumph Thunderbird is a reliably built machine, passing its MOT on first attempt 92.3% of the time—well ahead of the UK average of 80%—and only 14.4% of vehicles have ever recorded a dangerous defect, which is reassuringly low. With an average of just 0.56 failures per vehicle and 2.1 advisories, owners are dealing with genuinely minor wear items rather than systemic problems.

The median mileage of just 7,214 miles at test time suggests these are lightly used leisure bikes, so the high pass rate reflects both good build quality and gentle ownership patterns; don't expect the same results if you're buying one that's been regularly ridden. Check the service history carefully and budget for routine maintenance on the suspension and exhaust systems, which appear in the advisory records—these bikes reward consistent upkeep.

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

⚠️ Around 1 in 8 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.
