1998 Yamaha XJ600 0.6L Petrol · R416 AOM

The most recent DVSA examination on 25 February 2026 resulted in a clean pass with no advisories or defects recorded, indicating that at the point of test the motorcycle satisfied all statutory roadworthiness requirements. Looking back over the documented history, the overall trend is one of progressive improvement following a single failed test in July 2022. That earlier failure addressed significant safety items including a dangerously tread-deficient rear tyre, a shock absorber with negligible damping effect, and a stiff steering head bearing, alongside advisories for rear brake fluctuation and rear suspension component wear. Each subsequent annual test from 2022 through 2024 recorded a pass with only the persistent advisory regarding slight fluctuation in rear brake effort, which has now cleared entirely on the 2026 test. This trajectory suggests that the major mechanical concerns have been rectified and the machine is currently in a stable and compliant condition. With 37,367 miles recorded across approximately 28 years, the XJ600 has averaged around 1,335 miles annually, which is notably low usage for a motorcycle of this vintage. Such low annual mileage typically indicates either sporadic leisure use or extended periods of standing between rides, both of which carry their own mechanical implications rather than simply preserving the machine. Prolonged standing allows moisture to accumulate in the fuel system, promotes corrosion on exposed steel components such as brake discs and chain links, and accelerates the degradation of rubber parts through dry rot rather than wear. Conversely, the relatively modest mileage means internal engine components, transmission gears, and bearings have likely experienced limited mechanical stress. Given the low annual usage and the vehicle's age, a prospective buyer should prioritise condition-based assessments over mileage-based assumptions. The tyres warrant close inspection for sidewall perishing and cracking even if the tread depth remains legal, as rubber compounds harden and deteriorate with calendar age regardless of mileage. Brake discs should be examined for surface corrosion and the calipers checked for smooth operation, as seized slide pins or pistons are common after long periods of inactivity. The 12-volt battery should be load-tested, since batteries that have sat partially discharged will fail without warning, and the charging system output should be verified at the battery terminals with the engine running. Additional attention should be given to the cooling system, fuel system, and lubricants. Coolant loses its corrosion-inhibiting properties over time and should be replaced in line with the manufacturer's service schedule rather than purely on mileage intervals, so verify the age of the coolant in the expansion tank. The carburettors, if the bike retains the original setup, are prone to varnish and pilot jet blockages after standing, which can manifest as rough idle, hesitation on throttle application, or fuel starvation. Engine oil, fork oil, and brake fluid should all be considered for renewal based on age rather than solely on recorded mileage, and brake fluid in particular is hygroscopic and degrades in service regardless of miles covered. Finally, inspect the chain and sprockets for corrosion and check that the drive chain still flexes freely, as a rusted chain seized from standing can pose a significant safety hazard.
