2019 Yamaha YS 125 0.1L Petrol · AX19 SDZ

The vehicle remains roadworthy but the maintenance history shows a worsening trend of recurring mechanical defects that require attention. The most recent test in June 2026 at 13,766 miles flagged a loose drive chain, free play in the steering headbearing, and misaligned wheel alignment. These issues have persisted across the last three inspections, indicating that while the bike passes minimum legal standards, specific components are not being proactively replaced or adjusted during service intervals. At 13,766 miles over seven years, the motorcycle has covered a low average of approximately 1,967 miles per year. The data shows a consistent usage pattern, with a 1,944-mile gap between June 2024 and 2025, and another 1,720 miles between 2025 and 2026. While low mileage generally reduces engine wear, the presence of the steering headbearing and shock absorber issues suggests that rubber components and bearings are suffering from age-related degradation rather than mileage-related fatigue. A buyer must personally inspect the steering headbearing, as the free play has been a recorded defect since 2024 at 10,102 miles. This lack of tension can lead to poor handling and premature fork seal wear if not replaced. The drive chain and rear sprocket also require close scrutiny, as the tester flagged them as loose or worn in three consecutive years. Furthermore, the worn shock absorber bush noted in 2024 should be checked for fluid leaks or structural instability to ensure the low-mileage use has not resulted in internal component failure.
