2010 KTM 0.5L Petrol · YJ59 SWO

The most recent MOT on 17 March 2026 was passed, but it carried four advisories – a slightly stiff or notchy steering head bearing, slight play on both front and rear wheel bearings, and a slightly worn rear lower shock‑absorber bush. Over the six‑year MOT window the same three items (steering head bearing, wheel bearing play and rear shock bush wear) have been flagged each year, with tyre perishing and brake wear appearing intermittently. While the vehicle has never failed an MOT, the pattern shows a steady level of wear rather than any improvement, indicating that the underlying components have not been replaced or upgraded and that the wear is likely to progress if left unattended. Mileage has not been recorded, so a direct comparison with the vehicle’s ten‑year age is impossible. A typical 2010 KTM, if used as a daily commuter, would accumulate roughly 5‑8 000 miles per year; a significantly lower figure would suggest long periods of storage, which can accelerate corrosion, battery deterioration and rubber ageing, whereas a higher figure would imply more aggressive use and would be consistent with the recurring wear items noted in the MOT history. Without a mileage reading the buyer should treat the bike as if it has average usage and verify the odometer and service book for any gaps that might reveal unusually low or high mileage. The recurring steering head bearing stiffness or notchy feel should be examined by checking for excessive play when the handlebars are rocked and by listening for grinding or clicking during cornering. Front and rear wheel bearings that exhibit slight play may develop a humming or growling noise that intensifies with speed and may feel loose when the wheel is rocked laterally; any increase in noise or looseness should prompt immediate bearing replacement. The rear lower shock absorber bush, flagged each year as slightly worn, can lead to clunking or a vague knocking sensation over bumps and may compromise rear wheel alignment; replacement of the bush or the entire shock is advisable before the wear progresses to the damper rod. Tyres have been described as “slightly perished” and with side‑wall cuts, so the buyer must inspect tread depth, look for dry‑rot cracks, and ensure sidewalls are free of cuts that could develop into punctures. Brake pads were noted as close to the minimum limit in 2019 and a front disc was described as worn in 2020; the buyer should measure pad thickness and disc surface for scoring, and be prepared for pad replacement and possibly disc resurfacing or replacement if the disc has thinned beyond safe limits. Beyond the specific advisories, a ten‑year‑old motorcycle warrants a thorough age‑related inspection. Verify the 12 V battery’s charge and electrolyte level, and consider a load test as prolonged storage can cause sulphation. Check all fluid levels – engine oil, coolant (if liquid‑cooled), brake fluid and fork oil – and replace them if they have not been changed within the manufacturer’s time intervals, as fluids degrade with age even without mileage. Examine the frame, swingarm and exhaust for corrosion, especially around mounting points, and inspect suspension bushes, swingarm bearings and the chain for wear, proper tension and lubrication. Finally, confirm that the service book contains regular oil changes and any recommended component replacements; a well‑documented maintenance history will mitigate the risk associated with the recurring wear items highlighted in the MOT record.
