2004 Honda CG 125-4 0.1L Petrol · AE04 ZKY

A pattern of minor wear coupled with a single safety‑critical tyre failure defines the mechanical picture of this 2004 Honda CG125‑4; despite the 2023‑07‑18 MOT pass, the record shows recurring advisories on the steering head bearing, rear brake pedal travel and rear shock absorber damping, plus an earlier tyre tread warning that escalated to a dangerous failure in 2022. The overall trend is one of generally acceptable roadworthiness punctuated by specific components that have begun to approach the limits of acceptable performance. With only 11,530 mi recorded over 22 years the average annual accumulation is roughly 520 mi, well below typical usage for a commuter motorcycle. Such low mileage often points to periods of inactivity or very light riding, which can accelerate age‑related deterioration of rubber seals, bushings and corrosion‑prone metal parts even when wear from distance is minimal. The sparse mileage therefore does not guarantee component freshness; it simply shifts the risk profile toward age‑related degradation rather than high‑wear failure. Prospective buyers should give the steering head bearing close attention on a test ride: feel for any free play or wobble when applying gentle torque to the handlebars, and listen for clunking over bumps that could indicate the bearing’s clearance has increased beyond the advisory level. The rear brake pedal should be evaluated for travel length and firmness; excessive pedal travel or a spongy feel may confirm the advisory and suggest the need for a brake line inspection, pedal linkage lubrication or master cylinder service. Inspect the rear shock absorbers for reduced damping by noting any harsh rebound or lack of smoothness when compressing the rear suspension, and check the front suspension for any visible corrosion that could compromise mounting points. Finally, verify that the headlamp aim meets legal standards, as the 2018 failure recorded a low aim that can impair night‑time visibility and may require adjustment or replacement of the lamp assembly. While the tyre tread passed in the most recent test, the earlier warning about front tyre wear close to the legal limit suggests a thorough tyre depth check on both wheels before committing to purchase, with replacement considered if either tyre is approaching 1 mm. Addressing these specific items during a pre‑purchase inspection will give a clearer indication of the bike’s current roadworthiness and any imminent remedial work.
