Should I check the MOT history before buying a 2003 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 2003 Triumph Speed Four is virtually on par with the UK average, passing MOT first time at 80.5% versus 80% nationally, though one concern is that just over one in five of these bikes have recorded a dangerous defect at some point—something worth checking the service history for before purchase. These machines are running quite low mileage at a median of just 14,656 miles for their age, suggesting they may be cherished classics rather than hard-used commuters, and the 2.0 average failures per test combined with 6.0 advisories indicates minor wear accumulates rather than catastrophic issues. When you inspect one, focus on the advisory items—corrosion, worn bearings, and brake wear—as these are the patterns that emerge across the fleet rather than outright failures.

We have limited data for the 2003 Triumph Speed Four — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 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.
