Triumph Speed Triple (2003)
2003 Triumph Speed Triple
CarHunch analysed 212 real MOT records for the 2003 Triumph Speed Triple. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2003 Triumph Speed Triple passes its MOT on first attempt 87% of the time, meaningfully better than the UK average of 80%, which suggests these bikes are generally well-maintained by their owners. However, 17.9% have recorded a dangerous defect at some point, so a pre-purchase inspection by a qualified mechanic is worth the cost before committing.
These bikes sit at a low median mileage of just 15,630 for their age, pointing to careful, leisure-focused ownership rather than hard use—yet they still average 1.89 failures per test, indicating that age-related wear on seals, electrics, and exhaust systems catches up with even lightly-ridden machines. Before you buy, get a full service history check and have the fuel system, battery, and brake fluid condition inspected by someone who knows British bikes.
What to check before buying a 2003 Triumph Speed Triple
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.
