Should I check the MOT history before buying a 2006 Triumph Speed Four?

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 2006 Triumph Speed Four?

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.

The 2006 Speed Four passes its MOT on first attempt 81.6% of the time, marginally ahead of the UK average of 80%, but nearly a quarter of these bikes have recorded dangerous defects—a significant concern for any prospective buyer. With a median mileage of just 13,683 miles, these are genuinely low-mileage machines, though they average 1.73 failures per test, suggesting age-related wear outpaces actual usage.

The high advisory count of 6.2 per vehicle points to the kind of incremental corrosion and minor systems degradation you'd expect from a 17-year-old bike, even one that hasn't been thrashed. Before buying, get a pre-purchase inspection focused on that dangerous defect history—check the fuel system, brakes, and frame integrity carefully, as these issues are more common on this cohort than the average British motorcycle.

We have limited data for the 2006 Triumph Speed Four — treat the figures below as indicative rather than definitive.
