2008 Yamaha YBR 125 Custom 0.1L Petrol · YP58 APK

This Yamaha YBR 125 Custom presents a stable roadworthiness profile, with the most recent MOT tests—both the December 2025 pass and fail—showing no defects recorded at 36,853 miles. The absence of advisories or failures tied to critical components such as brakes, suspension, or structural integrity suggests that, at present, the bike is mechanically sound within the parameters of a standard MOT. However, the repeated pass/fail entries on the same day in both 2024 and 2025, without any faults listed, raises an anomaly worth investigating. Such inconsistencies could imply administrative errors, a tester oversight, or an unusually clean vehicle that passed minor checks on retest. For a buyer, this lack of recorded issues is positive, but the irregularity in test outcomes demands clarification from the seller before purchase. The bike’s mileage of 36,853 over 18 years—averaging just 2,047 miles annually—indicates either very light use or prolonged periods of inactivity. The recorded mileage drops between tests are minimal: just 439 miles between the 2023 and 2024 tests, and 439 miles again between the 2024 and 2025 tests. This stagnation suggests the bike may have sat unused for extended periods, which could lead to issues such as seized bearings, degraded seals, or flat-spotted tyres if not stored properly. The low mileage is not inherently problematic, but it does mean wear on consumables like tyres, brake pads, and suspension bushes may be uneven or deferred rather than evenly distributed. A buyer should verify whether the bike has been regularly exercised or left dormant, as this directly impacts long-term reliability. Given the clean MOT history, a prospective purchaser should prioritise a thorough pre-purchase inspection focusing on components typically overlooked in basic tests. Check the suspension for degraded bushes, worn coil springs, or signs of oil leakage from forks—common issues on lightly used bikes that may not have been stressed enough to trigger MOT advisories. Inspect the brake system for binding calipers, uneven pad wear, or glazed discs, as these can develop silently on a bike that hasn’t been ridden frequently. Examine the chain and sprocket for rust or excessive stretch, and verify that the final drive and swingarm bearings turn freely without resistance. Structural corrosion, particularly around the frame’s welds or subframe mounts, should be scrutinised, as low-mileage bikes are just as susceptible to rust if stored in damp conditions. Finally, confirm the battery health and electrical system functionality, as a bike that sits unused risks voltage drain or corroded connections.
