2021 Yamaha XSR 125 (MTM125) 0.1L Petrol · PJ21 XSO

This Yamaha XSR 125 has demonstrated a stable roadworthiness profile over the past two years, with the most recent MOT test on 26 January 2026 confirming no defects at 5,022 miles. The single failure on 16 January 2026—just six days prior—was unusually anomalous, as no specific issues were recorded, suggesting either a minor administrative oversight or a temporary operational hiccup at the testing centre. The preceding tests in January 2025 and January 2024 both passed without fail, indicating consistent compliance with MOT standards for critical systems. While the recent retest confirms current roadworthiness, the abrupt failure followed by immediate re-passage warrants scrutiny of whether the vehicle was subjected to unusual stress or neglect in the intervening period. The recorded mileage of 5,022 miles at the latest test reflects an exceptionally low annual average of approximately 1,004 miles over five years, a figure far below typical usage patterns for this class of motorcycle. The gaps between tests are irregular, with a 1,701-mile jump between January 2024 and January 2025, followed by another 1,019 miles to the 2026 failure. Such sparse mileage could imply prolonged storage, limited riding conditions, or deliberate deferral of maintenance. While low mileage generally reduces wear on high-stress components like suspension bushes, chain/drive system, and brake calipers, it also raises questions about whether fluids (brake, engine oil, coolant) have been refreshed according to manufacturer intervals, particularly if the bike was stored without proper care. Given the lack of recorded defects, the primary focus for an in-person inspection should centre on consumable items that are not MOT-tested but critical to long-term reliability. The chain and sprocket should be examined for excessive wear, lubrication quality, and proper tension, as prolonged inactivity can accelerate corrosion or dry-rotting of the chain links. Tyre tread depth and lateral wear patterns must be checked, as the absence of MOT failures does not guarantee they have been rotated or replaced at recommended intervals. The suspension (forks and rear shock) should be inspected for leaks, internal corrosion, or degraded bushings, especially if the bike was stored without protection. Additionally, the battery condition—critical for modern electronics—should be verified, as low usage may have allowed for partial discharge or corrosion at terminals. Finally, a thorough check of the exhaust system for rust penetration or cracked heat shields is advisable, given the potential for moisture damage during periods of disuse.
