The picture
Across 5,594 MOT tests, the Speed Triple returns 87.6% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A non-functioning shock absorber and brake pads worn below 1.0 mm round out the top three. Average tested mileage sits at 17,058, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 2.7-point gap between bands is modest — the year you buy Triumph Speed Triple makes a small but real difference to MOT outcomes.
Best band to buy
90.8%
2018–2020 registration
the 2018–2020 band climbs to 90.8% — a 2.7-point improvement. Tests in this band average 8,271 miles — roughly 10K miles fewer on the clock than the older band. Failures here are mostly wear items: missing, missing — the structural issues that drag down older examples don't appear in the top-10 for this band. The stricter post-2018 MOT test rules meant manufacturers had to tighten up emissions and electrical checks, but this band still shows far fewer major failures on suspension and bodywork than the older fleet.
Band to be cautious about
88.0%
Pre-2018 registration
On the older band (pre-2018), the data shows a 88.0% pass rate against a fleet average of 90.8% on the newer band. The main culprits logged at test: has a serious fluid leak, tread depth is below minimum requirements of 1.0mm, and not working. Average mileage on test for this band is 17,945 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (90.8% first-time pass). Worst band to avoid: pre-2018 (88.0% pass). That's a 2.7-point spread across 7,701 older tests and 130 newer ones — year of build makes a material difference on this model.

Recall history
The Speed Triple has 14 official UK vehicle recalls covering defect details, remedies, and affected build dates.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Speed Triple and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
