2010 Yamaha YBR 125 Custom 0.1L Petrol · DV60 VRD

The most recent DVSA test recorded on 3 November 2021 resulted in a Pass, albeit with a suite of advisories that echo those noted on the preceding failure a day earlier. The transition from a failed result on 2 November 2021 to a pass the following day indicates that the immediate cause of the failure – steering operation fouling on full lock – was remedied sufficiently to satisfy the MOT criteria, yet the persistence of multiple advisories shows that the underlying condition of the bike has not been fully resolved. The maintenance trend therefore appears to be marginally improving in terms of meeting statutory requirements, but it remains borderline and suggests that routine attention to the highlighted items has been inconsistent. At 13,267 miles recorded for a 2010 model, the average annual distance is roughly 830 miles, which is markedly below the typical usage pattern for a 125 cc commuter motorcycle. Such low utilisation often points to prolonged periods of storage rather than regular riding, and it can mask age‑related deterioration that is independent of mileage. The limited wear on moving parts may be offset by the effects of time on seals, rubber compounds, and metal corrosion, all of which can progress silently while the odometer remains static. Prospective buyers should give particular focus to the tyre condition, chain tension and lubrication, and steering geometry. The tyres were flagged as being close to the legal tread limit in 2021; even if the tread depth has not changed dramatically, sidewalls can develop cracks, dry rot, or become brittle after years of exposure, especially if the bike has been stored outdoors. Examine the tyres for any visible cracking, hardening, or uneven wear that could indicate mis‑alignment. The drive chain was described as slightly loose; check that the chain tension falls within the manufacturer’s specification, that the master link is secure, and that the sprockets show no signs of pitting or excessive wear. A chain that is too slack will produce a characteristic rattling on acceleration and may lead to premature chain stretch or sudden failure. The handlebar was noted as deformed yet serviceable and the steering head bearing was described as slightly stiff or notchy – both conditions can manifest as a vague clunk or resistance when turning the handlebars, especially at full lock where the earlier major fault was recorded. Verify that the steering column clears the fuel tank and bodywork throughout the full range of motion and that there is no binding, scraping or abnormal resistance. Any grinding, judder, or intermittent loss of steering feel during a test ride should be taken as a sign that the head bearing or bearing preload may need re‑adjustment or replacement. Given the bike’s age and the low‑mileage profile, a thorough age‑related inspection is essential. Inspect the frame and swing‑arm for corrosion, particularly in the joints and around the mounting points, as long periods of inactivity can allow rust to develop unnoticed. The 12‑volt battery, if original, is likely well beyond its service life and should be load‑tested or replaced pre‑emptively to avoid starting problems. Check all fluid reservoirs – engine oil, coolant (if liquid‑cooled), and brake fluid – for signs of contamination, water ingress or loss of viscosity; fluids deteriorate over time even without mileage and should be flushed and refilled according to the manufacturer’s calendar schedule. Finally, confirm that the service book contains stamps for regular oil changes, valve clearance checks and brake pad inspections; absent documentation, budget for a comprehensive service that includes brake disc inspection, brake pad wear measurement, suspension bush inspection and a full safety check before committing to purchase.
