2015 Yamaha MT 0.8L Petrol · RO15 XRN

A single dangerous rear tyre tread depth defect recorded at the most recent test on 27 May 2026 dominates the otherwise unblemished MOT history of this 2015 Yamaha MT, and warrants primary concern for any prospective buyer. The defect was listed alongside a rear exhaust noise advisory under item 8.1.1 (a), with the same exhaust noise also flagged as an advisory on the same day's pass certificate, indicating the rear silencer or mounting has deteriorated to the point where replacement is now overdue. Apart from this isolated failure and its associated advisory, the vehicle has accumulated a clean sequence of passes dating back to 2019 with no recorded defects of any kind, suggesting that the recent tyre and exhaust issues represent localised wear rather than a systemic deterioration of the motorcycle's mechanical condition. The recorded mileage of 38,822 miles over an 11-year span equates to a particularly low annual accumulation rate of roughly 3,529 miles, which points to either genuinely light commuting use or extended periods of standing. The MOT testing cadence is irregular rather than continuous, with gaps between the 2020 test in December and the next entry in October 2022, and another notable interval between October 2022 and May 2024, suggesting the motorcycle may have been off the road for periods or used only seasonally. Mechanically, such low and intermittent use typically manifests as dried and cracked rubber components, flat-spotted or perished tyres, stale brake fluid, surface corrosion on brake discs and calipers, and potential electrolyte issues in the battery, all of which can degrade rapidly even when overall mileage remains modest. Any prospective buyer should treat the rear tyre as a priority item and verify that a new tyre meeting current legal tread requirements has been fitted since the 27 May 2026 failure, checking the sidewall date code and inspecting both the rear and front tyres for signs of cracking, flat-spotting, or uneven wear given the low annual mileage. The rear exhaust should be physically inspected for rattles, blueing around joints, or loose mounting rubbers, and the system started from stone cold to listen for blowing or ticking that would confirm the 8.1.1 (a) advisory condition. On a test ride, attention should be paid to brake feel, as calipers that have sat idle can suffer from binding or sluggish pistons producing pulling under braking, and any standing periods should prompt a careful check that all electrical systems, instruments, and the charging system function correctly after the motorcycle has been running. Given the specific test outcome, a thorough pre-purchase physical inspection is advisable, ideally on a ramp so that the swinging arm, linkage, chain, and sprockets can be examined for surface rust and perished gaiters typical of low-mileage or stored motorcycles. The fork stanchions should be checked for pitting or oil seepage, and the brake discs measured for minimum thickness while the pads are inspected for corrosion rather than wear. Although the documented MOT record is largely clean, the single dangerous tyre failure and the exhaust advisory at the most recent test confirm that consumable replacement is now due, and the low usage pattern means further latent defects unrelated to MOT test items could easily be present and should be reflected in any purchase negotiation.
