2023 Triumph Street Triple RS 0.8L Petrol · AV23 PFX

The most recent MOT, carried out on 14 May 2026, was passed with no recorded defects or advisories. With only a single MOT entry available, the lack of any failures suggests that the vehicle has been maintained to a standard that meets the statutory safety and emissions requirements, and there is no indication of a deteriorating trend in the recorded test history. At three years old the Triumph Street Triple RS has logged just 5,928 miles, giving an average of roughly 1,976 miles per annum. This is considerably below the typical UK average for a sport‑bike of its class, which often exceeds 4,000 miles per year. Such low utilisation usually points to limited riding or extended periods of storage, and it reduces the cumulative wear on consumables such as tyres, brake pads and chain wear. However, prolonged inactivity can also accelerate age‑related degradation of rubber components, battery cells and corrosion of metal parts, so the mileage figure should be interpreted alongside the bike’s usage pattern. A prospective buyer should give particular attention to the tyre sidewalls for cracking, hardening or dry‑rot, as the polymer can deteriorate even when the tread appears acceptable. Inspect the tyre tread depth and check for uneven wear that might hint at mis‑aligned front forks or rear swing‑arm bearings. The 12‑volt battery, now approaching three years of service, should be load‑tested; a voltage below 12.6 V at rest or a rapid voltage drop under load would indicate impending failure, especially if the bike has been stored on a stand for long periods. Examine the coolant level, condition and any signs of leakage around the radiator and hoses, as coolant can become acidic over time and corrode the aluminium engine block if not changed on schedule. The suspension should be checked for any play in the front fork seals, worn bushings or leaking oil from the fork legs, which can manifest as a loss of damping or a clunking sensation over bumps. Verify that the rear shock absorber is free of external oil stains and that the swing‑arm bearings rotate smoothly without excessive play. Brake discs should be inspected for surface rust, especially if the bike has sat idle; light surface rust can be cleared with a few light applications of the brakes, but deep pitting or uneven disc wear would require machining or replacement. Finally, confirm that the service book is up‑to‑date with oil changes, chain lubrication and valve clearances recorded at the manufacturer‑specified intervals, as time‑based servicing is as crucial as mileage‑based maintenance for a high‑performance machine of this age.
