Used buying checklist
Triumph Speed Triple reliability, common problems and used buying checks
A used Triumph Speed Triple looks better than average for reliability in UK MOT data: 6.6% of 5,597 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for brakes, lights and electrical, and suspension and steering.
It can be, if the exact car has a clean history for brakes, lights and electrical, and suspension and steering.
Start with brakes, lights and electrical, and suspension and steering, then compare the car's mileage and recall record below.
Sources used: DVSA MOT tests (Apr 2026); vehicle recalls (Apr 2026); MOT fault wording (May 2025). MOT data does not capture every reliability issue, especially intermittent engine, gearbox or infotainment faults that do not appear during the test.
- 6.6% MOT failure rate
- Median tested mileage 14,695 miles
- 368 failed MOT tests analysed
Brakes is the clearest area to check
Brakes is the clearest named problem area in this model's MOT history (6.4 MOT notes per 100 tests). Example MOT phrases from this area include indicates excessive fluctuation of brake effort, is so short that the brake cannot be readily applied, and is bent and the brake cannot be readily applied.
Example MOT phrases to search in the car's history:
- indicates excessive fluctuation of brake effort
- is so short that the brake cannot be readily applied
- is bent and the brake cannot be readily applied
- The less effective brake control does not achieve an efficiency of 25%
- inoperative in the case of a single lamp or all lamps
- slightly damaged
- lens slightly defective
- does not illuminate simultaneously with the position lamp(s)
- modified so the suspension is inoperative
- component modified so the suspension is inoperative

Should you buy a used Triumph Speed Triple?
93.4% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 6.6%, -12.2 percentage points compared with the average across all models. This is a buying brief for the exact car in front of you: clean repeat history matters more than badge reputation.
- Repeat unresolved MOT notes for brakes, lights and electrical, and suspension and steering
- brakes appearing across more than one MOT
- Any dangerous MOT failure on the exact car, especially if the same area appears again later
- No paperwork showing applicable recall work has been completed
- A seller who cannot explain MOT wording such as "indicates excessive fluctuation of brake effort"
It can be, if the exact car has a clean history for brakes, lights and electrical, and suspension and steering.
Start with brakes, lights and electrical, and suspension and steering, then compare the car's mileage and recall record below.
Brakes is the clearest named problem area in the MOT history (6.4 MOT notes per 100 tests). These counts are issue notes, not failure rates, because a single MOT can list several faults.
Use the mileage table to judge whether the car is being viewed at a lower- or higher-risk mileage.
The MOT failure rate rises from 4.3% at 3-6 years to 7.9% at 15+ years. Compare the car with the nearest age range before treating a fault as normal wear or a warning sign. The average MOT failure rate across all models in the same dataset is 18.7%.
Start with brakes, lights and electrical, suspension and steering, and emissions, engine, and exhaust. The checklist on this page explains why each area is being recommended, what to inspect, and what to ask the seller.
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.

Recall records and data freshness
Recall context: are there safety notices to know about?
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
| 2019-11-26 | THE QUICKSHIFTER ASSEMBLY TSA BODY MAY COME INTO CONTACT WITH THE GEAR CHANGE LINKEAGE CLAMP ASSEMBLY The Quick shifter Assembly TSA body may come into contact with the gear change linkage. Replace the Clamp Linkage Assembly with a modified Clamp Linkage Assembly on affected models fitted with the Quickshifter Kit TSA |
|---|---|
| 2017-11-07 | RISK OF ELECTRICAL SHORT On affected machines there is a risk of one of the link leads to the regulator rectifier developing an electrical short. A bracket introduced at the start of production may interfere with the link lead resulting in damage to the outer protective sheathing and over time potentially exposing the wire. Contact between the bracket and the exposed wire may lead to an electrical short. In some cases the electrical short may cause an engine stall without warning. The original Link Lead will be removed and replaced with a new identical part which will be routed so as to avoid possible contact with the bracket edge. |
| 2015-05-11 | OIL MAY LEAK FROM SHOCK ABSORBER AND REDUCE EFFECTIVENESS OF REAR SUSPENSION The rear suspension unit has a possible assembly defect in that the piston-shaft nut has in some cases not been correctly tightened. If a defective suspension unit is fitted there could be an oil leak and a gradual loss of damping control which over time can adversely affect the handling of the machine. Recall the machines that are likely to be affected and replace the rear suspension unit. |
| 2013-05-27 | THROTTLE OPERATION MAY BE IMPEDED Insufficient guidance of the throttle cable in the headstock area can result in the throttle cable being trapped in the steering lock stop causing damage to the throttle cable which impedes its operation. Recall the vehicles that are likely to be affected to check the throttle cable and replace as necessary. Fit a wire guide to control the routing of the cable. |
| 2013-03-20 | ABILITY TO CHANGE GEAR MAY BE AFFECTED AND NEUTRAL INDICATED WITH GEAR SELECTED The instruments may indicate neutral is selected when the machine is in gear which could lead to the machine jumping forward at junctions or the rider changing gear unnecessarily. Additionally a weak detent arm spring could cause poor gear changing necessitating additional time selecting gears. Recall the machines that are likely to be affected to replace the detent arm spring and replace the neutral switch washer. |
| 2013-03-18 | INDICATOR STEM MAY NOT FUNCTION CORRECTLY It has been identified that the material for the front and rear indicator mounting stems have been manufactured from the incorrect material. This can result in the mounting stem failing and in extreme cases could allow the indicator to detach. Recall all affected machines and replace the front and rear indicator mounting stems |
