1998 Yamaha XJ400 0.4L Petrol · S571 EGJ

The Yamaha XJ400 presents a stable roadworthiness profile with a remarkably consistent maintenance trend. Since the most recent test in September 2023 at 37,465 miles, the vehicle passed with no defects or advisories recorded. This follows a streak of clean passes dating back to 2021, indicating that the mechanical and structural components have remained within acceptable operating parameters without the typical progression of visible wear or recurring failures. The mileage pattern is exceptionally low for a 28-year-old motorcycle, averaging approximately 1,338 miles per year. The data shows a significant gap in usage between May 2017 and April 2021, during which the bike covered only 102 miles. Since the 2021 test, usage has increased slightly, covering roughly 1,134 miles over the following two years. This low annual mileage suggests minimal mechanical wear on the engine and drivetrain, though the long periods of standing can often lead to the degradation of rubber components and fluid chemistry that an MOT may not detect. A buyer should focus their physical inspection on risks associated with low-mileage age and storage. While the MOT history shows no structural failures, the four-day gap between the failure and pass in May 2017 suggests a minor defect that was quickly rectified. In person, inspect the fuel lines for cracking and the fork seals for perished rubber, as these age regardless of miles driven. Given the low mileage, check the brake calipers for corrosion and ensure the tyres have not perished, as stationary vehicles are prone to flat spotting and internal dry rot despite high tread depth.
