2016 Yamaha YZF 0.1L Petrol · GL16 WHM

The most recent DVSA examination on 29 November 2025 resulted in a pass, which is positive, but the underlying trend is one of deterioration rather than stable maintenance. The 2024 test was completely clean with no advisories, whereas the 2025 tests show a cluster of concerning drive chain and tyre defects. Specifically, the 21 November 2025 test recorded a dangerous rear drive chain defect so severe it was deemed likely to fail, alongside major advisories for an excessively worn front sprocket and a worn rear drive chain, and a front tyre worn close to the legal limit with cracking in the treads. The pass just eight days later carried over the same tyre advisory plus a new advisory for a noisy exhaust. The compressed timescale between the failure and re-pass suggests remedial work was carried out on the chain and sprocket, but a prospective buyer should verify exactly what was replaced, whether the rear sprocket was also renewed as a matched set, and confirm that the original advisories have been properly resolved rather than simply masked. Annual mileage over the vehicle's ten-year life averages approximately 1,352 miles, which is exceptionally low and characteristic of a machine that has either seen very limited fair-weather use or has spent prolonged periods laid up. The MOT gap between April 2019 and November 2024 is itself indicative of either non-use or off-road storage, and the relatively modest mileage accumulation over that five-year window reinforces this likelihood. Mechanically, low annual mileage on a motorcycle of this age carries distinct risks: standing fuels can degrade, brake discs may have developed surface corrosion or the calipers may have seized, electrical connections can oxidise, and the battery is highly likely to have suffered from prolonged discharge cycles. Conversely, the engine, gearbox internals and main bearings will have seen minimal wear, which is a positive if the machine has been properly stored and serviced. Given the documented drive train issues, a physical inspection must focus on the chain and sprockets with particular care. Even after the recent work, check that the chain adjustment is within manufacturer tolerance and that the sliding plates and O-rings show no stiff links, as a chain that was allowed to run excessively loose can have caused accelerated wear on the countershaft and rear sprocket teeth. Inspect the front and rear sprocket profiles closely for hooked or pointed teeth, as fitting a new chain onto a worn sprocket will quickly destroy the new component. The front tyre was flagged as being close to the legal limit with cracking in the tread blocks, so confirm a replacement has been fitted or, if retained, examine the sidewalls and tread for perishing, as motorcycle tyres degrade from age regardless of tread depth, particularly on a low-use machine where ozone exposure can be significant. Listen on a test ride for any transmission snatch or vibration that might indicate chain or sprocket issues, and for any irregular brake feel that could point to a binding caliper from standing. Beyond the documented defects, several age-related and standing-related items warrant close attention. The exhaust was noted as noisy, which on a Yamaha YZF of this era commonly points to a perished mounting, a corroded joint, or failing internal baffles, so physically inspect the system for blueing, cracks and the integrity of the hangers and springs. Check the 12 volt battery voltage and load capacity, as a ten year old original unit will almost certainly be at or near the end of its service life even if it currently holds a charge. Inspect the brake discs for lipping, pitting and surface rust, and verify that the calipers release cleanly without binding. Examine the fuel system for evidence of stale fuel, and confirm that brake fluid, coolant and fork oil have been serviced in line with calendar intervals rather than purely by mileage, as time-based degradation of these fluids is a common oversight on low-mileage machines. Finally, verify the service book stamps or digital history to ensure the long storage periods were accompanied by appropriate recommissioning work, and consider a compression test and an electronic diagnostic scan to confirm the engine management and ABS systems, where fitted, are functioning correctly after extended inactivity.
