2021 Triumph Tiger 900 GT PRO 0.9L Petrol · VU71 AZO

The 2021 Triumph Tiger 900 GT Pro received its latest MOT test on 2025-11-14, which passed without any failures, though it carried an advisory regarding front brake fluctuation, a condition noted in both the 2024-10-07 and 2025-11-14 tests. This recurring advisory suggests a persistent but non-critical issue with the brake system’s hydraulic balance, likely linked to uneven wear on brake pads, discs, or master cylinder function. The absence of more severe failures or additional advisories over the past two years indicates a stable maintenance trend, though the brake fluctuation should be monitored closely. The vehicle’s consistent MOT results, combined with the low mileage, suggest that while the owner has likely maintained regular servicing, the brake system’s longevity may be influenced by the observed hydraulic irregularity. The recorded mileage of 15,596 miles for a vehicle aged five years represents an annual usage rate of approximately 3,119 miles, which is notably lower than industry averages for similarly equipped sport bikes or performance cars of this era. Such low mileage often reflects periods of storage, limited operational use, or seasonal disuse, which can lead to specific wear patterns and potential issues related to standing conditions. For example, prolonged idling or stationary periods may accelerate corrosion in brake systems, particularly on calipers and discs, leading to binding or reduced braking efficiency. Additionally, fluids like brake fluid and engine oil degrade over time even when not actively used, so the vehicle’s age and low mileage warrant a focus on calendar-based maintenance rather than mileage-dependent checks. As a prospective buyer, the most critical areas to inspect during a physical examination of this Triumph Tiger 900 GT Pro include the brake system, given the recurring advisory and the vehicle’s age. Prioritise checking for signs of brake disc corrosion or binding calipers, which could exacerbate the hydraulic fluctuation observed in the MOT tests. Listen for any unusual brake pedal feel—such as sponginess, vibration, or uneven resistance—while driving, as these symptoms may indicate fluid contamination, pad wear, or master cylinder issues. Inspect the brake discs for uneven wear, grooves, or glazing, and verify that the calipers are free from sticking or seizing. If the brake system appears clean but the advisory persists, consider a professional inspection to assess whether the issue stems from a minor hydraulic adjustment or a more significant component failure. Beyond the brakes, given the vehicle’s low mileage and age, focus on the following checks to ensure long-term roadworthiness and performance. Examine the tyres for sidewall perishing or cracking, which can compromise structural integrity and safety, especially on a high-performance bike like this model. Check the tyre tread depth thoroughly, as the advisories from the 2024 test highlight wear close to legal limits, and consider replacing them if they approach 1.6mm or less. Inspect the 12V battery for signs of corrosion on terminals, swelling, or poor electrical connections, as standing vehicles can accelerate battery degradation. Additionally, verify the service history for time-based fluid replacements, such as engine oil, coolant, and brake fluid, which should have been serviced within the recommended intervals (typically every 2–3 years for oil, and annually for brake fluid). Finally, conduct a visual inspection of the exhaust system for leaks, rust, or structural damage, as emissions-related issues could arise from prolonged inactivity. If the vehicle has been stored in a damp or poorly ventilated environment, address any rust formation on the frame, suspension components, or undercarriage to prevent long-term corrosion.
