1977 Harley-Davidson 1.3L Petrol · XLG 764R

The most recent MOT, carried out on 19 November 2022, was passed but returned two advisories: a noisy exhaust and rear tyres approaching the legal tread limit. Across the seven‑year record the vehicle has consistently passed the test, with the only failures relating to the registration plate – a non‑mechanical compliance issue – and the same exhaust advisory appearing at every inspection. This pattern indicates a generally stable mechanical condition, though the persistent exhaust noise suggests a component that has not been addressed and may be deteriorating. With only 31 485 miles recorded on a 2002 model, the average annual mileage works out at roughly 1 300 miles per year, which is exceptionally low for a twenty‑four‑year‑old machine. Such limited use often points to long periods of storage rather than heavy riding, meaning wear on consumables such as tyres, brake pads and fluids will be more a function of age than mileage. However, low utilisation can also allow corrosion to set in on suspension bushes, brake discs and the chassis, especially if the bike has been stored outdoors or in a damp environment. Prospective buyers should give particular attention to the exhaust system. A noisy exhaust can arise from a cracked pipe, loose mounting, or a failing silencer, and may be accompanied by a faint hissing or rattling sound that becomes louder under acceleration. Inspect the exhaust for rust, holes or loose clamps, and verify that the muffler is securely attached. During a test ride listen for any change in pitch when revving, and feel for vibration that could indicate a mis‑aligned pipe. The rear tyre advisory from 2022 signals that at least one tyre was close to the minimum 1.0 mm tread depth; even if the tyre has been replaced since, the age of the rubber may have caused cracking or dry‑rot. Examine both tyres for sidewall cracks, hardening of the tread compound and uneven wear patterns that could betray mis‑aligned rear suspension or worn rear swing‑arm bearings. Given the bike’s age and low mileage, a thorough age‑related inspection is essential. Check the battery for sulphation and verify it holds charge, as long periods of inactivity can reduce capacity. Inspect the front and rear suspension bushes, coil springs and swing‑arm bearings for corrosion, pitting or loss of compliance; any play or clunk when the bike is rocked front‑to‑rear or side‑to‑side is a warning sign. Examine the brake discs for surface rust, scoring or uneven thickness, and ensure the calipers move freely without sticking. Finally, confirm that the engine oil, coolant (if liquid‑cooled) and brake fluid have been changed within the recommended calendar intervals, as fluids degrade over time regardless of distance travelled. A comprehensive visual and road‑test appraisal addressing these points will give a clear picture of the motorcycle’s true roadworthiness.
