Should I check the MOT history before buying a 1998 Triumph Speed Triple?

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 1998 Triumph Speed Triple?

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 1998 Triumph Speed Triple?

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.

Is the 1998 Triumph Speed Triple reliable?

Based on MOT data from 134 vehicles, the 1998 Triumph Speed Triple has a first-time MOT pass rate of 83.1%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 1998 Triumph Speed Triple?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 1998 Speed Triple passes its MOT slightly above the UK average at 82.5%, and dangerous defects are relatively uncommon at 15.7%—a reassuring sign for a bike now 26 years old. However, the median Carhunch score of 50 reflects the reality that age and wear are catching up: these machines average 2.1 failures and 7.4 advisories per test, suggesting componentwise deterioration is the norm rather than the exception.

At 20,000 miles median, these bikes are ridden moderately rather than thrashed, which helps explain the respectable pass rate—but that also means high-mileage examples will likely need targeted work. If you're considering one, prioritise a pre-purchase inspection focusing on the fuel system, exhaust, and brake components, which typically drive the advisory list on air-cooled British twins of this generation.
