1998 Yamaha XJ900 0.9L Petrol · S683 AMR

This 1998 Yamaha XJ900 presents a mixed mechanical picture across its recorded MOT history, with a pattern of intermittent but specific failures layered on top of an otherwise reasonable pass rate. Five of the seven recorded tests resulted in passes, including the most recent examination on 10 April 2026, but that same date also produced a fail on a single advisory-equivalent item: a missing rear reflector. More significant is the March 2024 failure, which flagged major defects on the front brake system including excessive binding and insufficient lever reserve, alongside a major defect on the rear suspension linkage where the arm pin or bush was recorded as excessively worn. That 2024 cluster represented the most mechanically serious event in the record, and a prospective buyer should treat it as the defining reference point for the motorcycle's underlying condition rather than the clean April 2026 pass. Additionally, the January 2023 failure recorded a registration plate non-conformity and a minor reflector positioning issue, while the 2025 test carried advisory notices on both front and rear tyres approaching the legal limit. The overall trend suggests the motorcycle is roadworthy at present but has demonstrated genuine mechanical weaknesses in its braking and suspension components within the last three years. The mileage context for this vehicle is effectively absent from the records provided, making any assessment of usage intensity or annual accumulation rates impossible. MOT certificates for motorcycles of this era do not always carry recorded mileage, and the absence of consistent odometer readings across the test history means that it is not possible to confirm whether the XJ900 has covered high or low distances during its twenty-eight-year life. There are notable gaps between tests, including a fifteen-month interval between the June 2021 pass and the January 2023 test, and an almost fourteen-month interval between the January 2023 pass and the March 2024 failure. These gaps in themselves do not indicate any specific mechanical concern but do mean that usage patterns remain undefined. Without mileage continuity, a buyer cannot infer anything about engine wear rates, brake pad longevity, or suspension component fatigue intervals. Given the documented defects, the front brake system should be the primary focus of any pre-purchase evaluation. The 2024 failure recorded the front brake lever as having insufficient reserve travel and the caliper as excessively binding, both of which are conditions that can recur if the caliper slides, pistons, or master cylinder were not properly refurbished at the time. During a test ride, the buyer should pull the front brake firmly and hold it for several seconds, feeling for any gradual lever travel that would suggest internal seal leakage, and check whether the lever returns smoothly and fully without any stickiness that might indicate a binding caliper piston. The motorcycle should also be pushed forward and backward with the brake released to confirm the front wheel spins freely without any scraping or resistance, which would suggest the caliper is still binding. Additionally, the front brake disc should be inspected visually for any lipping or scoring that could indicate uneven pad wear. The rear suspension linkage flagged in the 2024 major defect warrants direct physical inspection. The recorded failure identified the arm pin or bush as excessively worn, which on a motorcycle of this vintage typically involves worn needle bearings or rubber bushes within the linkage assembly. The buyer should place the motorcycle on a centre stand or have a second person support it while weight is applied alternately to each side of the rear subframe, checking for any clunking, free play, or vertical movement at the linkage pivots. With the rider's weight applied through the rear suspension, any knocking or looseness felt through the seat would confirm worn bushes. The 2025 advisory on tyre wear close to the legal limit also means a current inspection of both front and rear tyre tread depth is essential, as tyres fitted at that test will now be approaching three years of service. Finally, the exhaust advisory from the 2024 test for a minor gas leak should be checked by listening for any ticking or hissing from the exhaust joints during a cold start, as corrosion at the header pipe gasket is a common failure point on older motorcycles.
