2007 Yamaha DT125 0.1L Petrol · PN07 OHT

The most recent MOT inspection on 17 February 2025 resulted in a pass, though it introduced two specific advisories regarding the rear brake and the drive chain. Looking at the broader history, the maintenance trend appears to be transitioning from a period of clean passes in 2022 and 2023 to a stage where age-related wear is becoming evident. While the vehicle has successfully passed its tests, the emergence of these advisories suggests that the motorcycle is entering a phase where more frequent mechanical attention will be required to maintain its roadworthiness and prevent future failures. With a recorded mileage of 19,981 over nineteen years, this Yamaha DT125 has been used very sparingly, averaging approximately 1,052 miles per annum. This low usage profile is a double-edged sword for a prospective buyer. While it indicates minimal engine running hours and reduced wear on internal components like pistons and cylinders, it also strongly suggests the vehicle has spent significant periods stationary. Long-term standing can lead to issues that mileage alone does not capture, such as the degradation of rubber components, fluid contamination, and the onset of corrosion on exposed metal surfaces or brake components. During your physical inspection and test ride, you must pay close attention to the advisories noted in the latest MOT. The report of a rear brake binding suggests that the rear caliper or drum mechanism may be sticking, which could be caused by a seized piston or a faulty return spring. On a test ride, listen for any unusual dragging sensations or check for excessive heat buildup at the rear wheel after riding. Additionally, the tight drive chain requires attention; a chain that is too tight can cause undue stress on the sprockets and the transmission. Inspect the chain for kinks, rust, or uneven tension, and ensure the sprocket teeth are not excessively worn or hooked. Given the low annual mileage and the age of the vehicle, you should perform a thorough check for age-related degradation. Inspect the tyres closely for sidewall cracking or perishing, as rubber compounds lose elasticity over time regardless of tread depth. Check the suspension stanchions for any signs of corrosion or oil leaks from perished seals, and examine the fuel system for signs of varnish or blockage caused by old fuel. It is also vital to verify the service history to ensure that oil and fluid changes have been carried out on a calendar basis rather than solely based on mileage, as lubricants degrade chemically over time even when the engine is not in use.
