1999 YAMAHA R11.0L PETROL

The most recent MOT entry for this 1999 Yamaha R1 is dated 2017-08-04, which shows a failure due to the rear stop lamp not illuminating immediately when the brake is applied (1.3.1a). This is a safety-critical defect affecting rear lighting. However, the same date also lists a pass with no defects recorded, creating ambiguity. This inconsistency may indicate a data entry error or a duplicate record, but the failure note remains the most relevant concern. The vehicle’s MOT history reveals a stable pattern of minor issues. Earlier entries from 2013 and 2012 noted front tyres worn close to the legal limit (4.1.3(ii)), but these were resolved, as the 2015 and 2017 MOTs showed no defects. The 2017 failure is the only recent significant defect, suggesting the rear lighting system may require attention. No other recurring faults or worsening trends are evident in the history. The vehicle is 27 years old with 16,975 miles recorded, averaging 629 miles per year —a very low mileage for its age. This could indicate light use or long periods of inactivity , which may lead to issues like electrical system degradation, corrosion, or fluid stagnation.
