2003 Suzuki GN125 0.1L Petrol · PL03 JCJ

The most recent MOT test conducted on 5 August 2025 resulted in a pass with no recorded defects. Looking at the broader historical data, the maintenance trend for this Suzuki GN125 appears exceptionally stable. The vehicle has consistently passed its inspections without any noted advisories or failures over the documented periods, which suggests a high standard of upkeep or a very well-preserved mechanical state. The recorded mileage of 16,460 miles is remarkably low for a vehicle of this age, representing an average annual usage of approximately 716 miles. While this low mileage implies minimal wear on the engine internals, piston rings, and gearbox, it also indicates that the motorcycle has likely spent extended periods stationary. For a small-capacity machine, this usage profile shifts the mechanical concern away from component wear and towards the degradation caused by inactivity and time-based chemical breakdown. Given the low usage and clean MOT history, a prospective buyer must prioritise inspecting age-related perishables rather than mileage-related wear. Thoroughly examine the tyres for sidewall cracking or perishing, as rubber degrades over time regardless of tread depth. You should also check the brake fluid for clarity; if it appears dark, it may have absorbed moisture, which can lead to internal corrosion or brake fade. Inspect the brake calipers for signs of binding or seized pistons, a common symptom of motorcycles that sit for long durations without regular movement. Further inspection should focus on fluid and structural integrity. Verify the condition of the drive chain, looking for stiffness in the links or surface corrosion, and ensure the fuel system is free from varnish or sediment caused by old petrol. Check the battery terminals for any signs of oxidation and test the electrical system for consistent voltage. Finally, inspect the exhaust system and various fasteners for surface corrosion or pitting, and confirm that all rubber components, such as fork seals and intake manifolds, remain supple and free from cracks.
