2018 Yamaha MT-09 ABS 0.8L Petrol · PL18 LPC

The 2018 Yamaha MT-09 received its latest DVSA MOT on 23rd June 2025, where it passed with a single advisory regarding the rear brake system showing slight fluctuation in brake effort. This latest inspection follows a history of consistent MOT passes with no failures, though two advisories were noted in previous years—one for a drive chain that was deemed slightly loose and another for a shortened clutch lever. The absence of repeated failures or critical defects over the past three years suggests a stable maintenance trend, though the recurring advisories indicate areas of wear that require closer attention. The rear brake advisory, in particular, warrants immediate investigation, as brake effort fluctuation can stem from worn brake pads, warped discs, or binding calipers, all of which could compromise braking performance if left unaddressed. The recorded mileage of 47,840 miles for a vehicle aged eight years represents a relatively low annual usage rate of approximately 5,980 miles per year, which is notably below the average for a similarly aged sportbike. Such low mileage can result from periods of inactivity, particularly if the bike has been stored in a garage or kept in a stationary condition for extended durations. However, prolonged standing without regular operation can lead to specific issues, including corrosion in the brake system, particularly on brake discs and calipers, which may cause binding or reduced braking efficiency. Additionally, the clutch lever being shortened suggests potential wear in the clutch mechanism, which could indicate internal clutch plate or pressure plate degradation over time, even at lower mileage. The drive chain advisory from 2022 also implies that the chain may have stretched or worn internally, requiring eventual replacement to prevent increased wear on the sprocket and chain guides. For prospective buyers, the most critical immediate checks should focus on the rear brake system, given the recent advisory. Inspect the rear brake discs for signs of warping, corrosion, or uneven wear, and verify that the calipers are not binding or seized. Listen for any unusual noises during braking, such as grinding or squeaking, which could indicate worn pads or damaged discs. The shortened clutch lever should prompt a visual inspection of the clutch assembly, including the pressure plate and flywheel, for signs of wear or damage. The drive chain should be tensioned and inspected for elongation or excessive play, with a recommendation to replace it before it causes further damage to the sprocket or chain guides. Beyond these mechanical concerns, given the bike’s age and low mileage, examine the tyres for sidewall cracking or perishing, which can occur even at low mileage if stored in poor conditions or exposed to UV degradation. Check the 12V battery for voltage output and overall health, as older batteries may struggle under prolonged inactivity. Finally, verify that the service book records reflect any scheduled fluid changes, particularly for the clutch fluid, transmission fluid, and coolant, as these fluids degrade over time regardless of mileage. If the bike has been stored for extended periods, consider draining and refilling the cooling system to prevent corrosion and thermal damage.
