1991 YAMAHA FJ12001.2L Petrol

The vehicle is currently unroadworthy following a failure on June 6, 2026, 72,320 miles. While the motorcycle maintained a clean record between 2022 and 2024, the maintenance trend has shifted towards worsening mechanical and electrical neglect. The 2025 test already flagged issues with brake effort fluctuation and a binding rear caliper, which have escalated into a formal failure involving front brake instability and multiple electrical faults in the rear lighting circuit. At 72,320 miles, this 35-year-old Yamaha shows an exceptionally low average of approximately 2,066 miles per year. The data indicates consistent low-usage patterns, with only 221 miles recorded between the April 2025 and June 2026 tests. This low mileage often suggests the vehicle sits for long periods, which frequently correlates with the mechanical issues observed. Stagnation leads to degradation of rubber seals and internal corrosion within brake lines, likely contributing to the binding calipers and effort fluctuations seen in the recent history. A buyer must prioritize a thorough inspection of the braking system to address the recurring fluctuations in brake effort noted in both 2025 and 2026. These symptoms suggest air in the lines, a failing master cylinder, or perished pistons within the calipers. The recurring rear electrical failures, specifically the reduced intensity and interference issues, indicate corroded wiring or poor earthings connections common in low-mileage vintage bikes. Given the age and low mileage, a physical inspection should also target the frame for structural rust and the fuel system for varnishment, as the MOT record does not cover these internal engine components.
