2014 Triumph S 0.7L Petrol · SL14 NFV

A chronic steering headbearing advisory has defined the mechanical profile of this 2014 Triumph S across its recent testing history, with the same defect first noted in July 2022 and then re-flagging in July 2024, suggesting the issue has neither been rectified nor has it deteriorated into a frank failure. The most recent examination on 16 July 2025 produced a pass alongside a minor defect for a registration plate lamp throwing direct white light to the rear, the same item which independently caused a failure notice on that date due to a missing rear reflector classified as a prs item. These lighting issues are trivial in isolation, but the absence of any further advisories on the 2025 test implies the front brake fluctuation noted two years ago has at least not worsened into a measurable imbalance, and no new corrosion, tyre, suspension, or drivetrain concerns have been introduced into the record. At only 6,147 recorded miles across twelve years, this machine averages an exceptionally low 512 miles annually, a figure that places it firmly in low-use territory and raises legitimate questions about whether it has been ridden regularly or left standing for extended intervals. The MOT cadence from 2022 through 2025 is consistent year on year, indicating the machine has been kept on the road throughout, although the very modest mileage accumulation between tests confirms that usage has been light rather than active. Mechanically, such restraint typically preserves major drivetrain components but places disproportionate stress on items that suffer from inactivity: headbearings can stiffen from infrequent rotation, brake calipers can bind through lack of regular application, tyres can harden and crack well before their tread depth is exhausted, and oil can lose protective qualities while the machine sits idle. The fact that headbearing stiffness has now appeared twice in three years is fully consistent with the side effects of sporadic use. For a prospective buyer, the priority on inspection should be a focused evaluation of the steering headstock assembly, as this is the only component to attract a recurring advisory. On a test ride, the steering should be checked for any notchiness or hesitation as the forks are turned from lock to lock with the machine stationary on its centrestand, and any binding or roughness felt through the handlebars would confirm that the bearings require immediate attention. The front brake, which showed slight fluctuation of effort in 2024, should be examined for smooth and even response under progressive lever application; any judder or uneven pulling would suggest a sticking caliper piston or a warped disc, both plausible outcomes given the low annual mileage. Given the very low odometer reading, the brake fluid should be assumed to be original and due for replacement, and the tyres should be inspected closely for perishing or sidewall cracking even if legal tread depth remains, as motorcycle rubber compounds deteriorate with age regardless of mileage. Finally, the practical effect of the 2025 failure for the missing rear reflector and the white-light registration plate issue should not be overlooked, as they indicate a recent compliance lapse that will need rectifying before the machine is presented for its next test. A walk-around should confirm the reflector is now securely mounted and that the number plate illumination produces only steady red light when viewed from behind. Beyond that, given the very low usage pattern, a general service including fresh oil, a new battery if the original is still fitted, and replacement brake fluid would be prudent commissioning work to bring the machine back to a reliable operating baseline. Subject to the steering and brake checks returning satisfactory results, this Triumph S presents as a low-mileage example whose mechanical story is dominated by inactivity-related advisories rather than any sign of wear-through or structural deterioration.
