2002 Honda CG125 0.1L Petrol · FG02 BVT

A twenty-four-year-old Honda CG125 with a single passing MOT on record and no failures to its name presents a mechanical profile built around two specific advisories that any prospective buyer needs to investigate carefully. The most recent test on 23 September 2021 issued an advisory for rear wheel alignment being slightly misaligned and another for the steering headbearing being slightly stiff or notchy. While neither defect was serious enough to cause a failure at that examination, both represent the early stages of component wear or adjustment drift that could progress over time. A motorcycle of this vintage with limited recorded testing history means there is little trend data to confirm whether these issues have stabilised, been rectified, or deteriorated. The absence of any repeat advisories or subsequent tests simply leaves the question open until a hands-on assessment is carried out. At 14,359 recorded miles against a twenty-four-year manufacturing date, this CG125 averages approximately 598 miles per year, which is exceptionally low for any road-going motorcycle and strongly suggests prolonged periods of storage or very occasional short-trip use. Such low annual accumulation can be deceptive on a small-capacity commuter machine, as the biggest mechanical threats are not necessarily distance-related wear but rather the consequences of standing idle. Rubber components including tyres, fork seals, and dust covers can perish or harden when a bike is left unused, while brake calipers can seize through corrosion, fuel systems can suffer from varnish build-up in the carburettor, and electrical connections can oxidise. The lack of dense mileage also means that components which would normally be replaced through routine service intervals may still be fitted with original or long-aged parts, particularly in areas such as the drive chain, sprockets, brake hoses, and cables. From a buyer's perspective, the rear wheel alignment advisory warrants immediate attention because on a single-shock or twin-shock CG125 it typically points to worn swingarm bearings, a bent or fatigued swingarm, or incorrect chain tension masquerading as misalignment. On a test ride, listen for any clonking from the rear end over bumps, check whether the chain tension is uneven or the rear wheel sits visibly off-centre in the swingarm, and verify that the chain adjusters are equally positioned on both sides. The steering headbearing advisory suggests the top or bottom taper roller bearings are either dry, pitted, or incorrectly adjusted. With the front wheel lifted off the ground, the steering should fall freely under its own weight from lock to lock; any notchiness, resistance, or a gritty feel confirms the bearings need inspection, and any front-to-back movement when the fork crowns are rocked against the steering lock indicates bearing preload is too loose. Beyond the flagged components, the low-mileage storage profile makes a careful inspection of the braking system essential, as caliper pistons and brake hoses degrade with age regardless of mileage. Check that both front and rear calipers release cleanly without the pads dragging and that there is no sponginess in the lever or pedal that might indicate perished internal brake seals or flexible hose deterioration. Inspect the condition of the tyres closely for sidewall cracking or perishing typical of aged rubber, and confirm the fork stanchions are free of pitting or oil seepage from the seals. Examine the carburettor for any signs of petrol staining, and verify that the battery holds charge and the electrics function reliably, as long storage frequently causes electrical gremlins. Finally, a compression test or at minimum a healthy kick-start action with even cranking resistance will confirm the top-end condition of this small single-cylinder engine, which remains the heart of the machine's long-term reliability.
