The 2004 Speed Triple 955i passes its MOT on first attempt 82.4% of the time, marginally above the UK average of 80%, which suggests a reasonably solid bike from a reliability standpoint—though the 17.3% of machines that have recorded dangerous defects is worth taking seriously during your inspection. At an average mileage of 17,175 for a 20-year-old bike, these aren't garage queens, yet they're averaging 1.74 failures per test, indicating age-related wear rather than systemic problems.

The high advisory count of 7.0 per vehicle reflects the typical nibbles of an older sportsbike: corroded fasteners, tired seals, worn brake pads—maintenance irritants rather than deal-breakers. Before committing, budget for a thorough pre-purchase inspection focused on the cooling system, exhaust condition, and frame cracks, as these emerge as common failure points on this model's MOT history.

We have limited data for the 2004 Triumph Speed Triple 955i — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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.
