Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Trident T150v is likely to perform.
Motorcycle lighting and signalling — 6.5% of failures
Motorcycle lighting and signalling issues account for 6.5% of MOT failures on the Triumph Trident T150v. Motorcycle lighting and signalling issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
Motorcycle lamps and reflectors — 4.8% of failures
Motorcycle lamps and reflectors issues account for 4.8% of MOT failures on the Triumph Trident T150v. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Motorcycle body and structure — 3.2% of failures
Motorcycle body and structure issues account for 3.2% of MOT failures on the Triumph Trident T150v. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
