Should I check the MOT history before buying a 2003 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 2003 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 2003 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 2003 Triumph Thunderbird passes its MOT first time at 89.2%, well above the UK average of 80%, and dangerous defects are uncommon at just 10.2% of vehicles—making this a genuinely reliable choice for a 20-year-old bike. The low dangerous defect rate combined with a strong pass rate suggests these motorcycles have been well looked after by their owners.

At 11,234 miles median, these Thunderbirds have been ridden sparingly for their age, which partly explains the robust reliability picture. Each vehicle averages 1.36 failures and 3.8 advisories per test, pointing to minor wear rather than structural problems—so when you're evaluating a specific used example, focus your pre-purchase inspection on fluid leaks, tyre condition, and the charging system rather than anything catastrophic.

⚠️ 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.
