2014 Yamaha WR 0.1L Petrol · DY64 MKX

Chain wear and steering head‑bearing play dominate the MOT narrative for this 2014 Yamaha WR. The most recent pass in May 2026 still carries an advisory for slight free play in the steering head bearing and notes that the drive chain is worn, albeit not yet beyond the limit for a pass. A failure recorded two years earlier flagged the chain as excessively loose and the horn as inoperative, indicating that chain tension has been a recurring issue and that the horn fault was remedied before the subsequent pass on the same date. At 29,163 miles after twelve years the annual mileage averages just over 2,400 mi, well below the typical usage for a dual‑sport motorcycle. Such low utilisation often points to extended periods of storage or very light riding, which can be gentle on high‑wear components but may allow rubber and polymer parts to age in situ. The modest mileage does not automatically guarantee component longevity; rather, it suggests that wear on the drivetrain and suspension may be less advanced than on a higher‑mileage counterpart, while seals, hoses and the chain’s protective coating could have deteriorated from inactivity. When inspecting the bike, give the drive chain immediate attention. Verify correct tension with the prescribed finger‑gap measurement, look for elongated links, stiff or rusted rollers, and listen for a rattling or slapping sound under acceleration or load. Even though the MOT advisory classifies the wear as non‑excessive, the earlier failure for excessive looseness implies the chain may be approaching its service limit and could require replacement or a thorough overhaul soon. Test the horn function on the stand‑alone button and the steering wheel; a non‑working horn is a safety defect, and any increase in steering play beyond the slight free play noted could manifest as a vague wobble or uneven tyre wear during cornering. Finally, a comprehensive pre‑purchase check should include the steering head bearings themselves – feel for any looseness or binding when the handlebars are rocked side‑to‑side, and watch for abnormal noises when the bike is lifted and the front wheel turned. While no brake or tyre defects appear in the MOT record, confirm that brake pads retain adequate thickness, discs are free of scoring, and tyres show even tread wear, as low mileage can sometimes mask hidden surface degradation. A full visual inspection for oil or coolant leaks, especially around the engine casings and swing‑arm pivots, will also help ensure that the low‑usage history has not allowed internal seals to dry out.
