2015 Sinnis JS 0.1L Petrol · GP15 BYC

The 2015 Sinnis JS currently holds no valid MOT certificate, having failed its most recent test on 6 July 2022 at 5,357 miles. The maintenance trend is clearly worsening. A clean pass recorded on 7 June 2021 at 4,858 miles was followed by five separate defects twelve months later, indicating a marked decline in basic upkeep during that final year of testing. The vehicle has not been presented for re-examination since that failure, meaning it has stood without a valid certificate for nearly four years. The mileage profile is exceptionally low. Across eleven years of age, the odometer has recorded just 5,357 miles, averaging roughly 487 miles annually. The record shows only 499 miles accumulated between June 2021 and July 2022, and zero miles since the July 2022 failure. Such prolonged inactivity raises concerns beyond the flagged defects. Seals, gaskets, and flexible hoses deteriorate with age and lack of use regardless of mileage. Fuel left standing in the tank and carburettor risks varnish formation and blockages. Tyres fitted during the last test will now be over four years old and may show sidewall cracking even if tread depth remains adequate. A buyer should focus the physical inspection on the items that caused the 2022 failure. The front headlamp not functioning on dipped beam suggests a failed bulb, connector fault, or wiring issue. Both the drive chain condition and the rear sprocket looseness point to neglected adjustment and lubrication, which on a low-mileage machine often results from infrequent use rather than high wear. The slight fluctuation in front brake effort could indicate a warped disc, contaminated pads, or a sticking caliper, all of which deteriorate when a motorcycle sits stationary for extended periods. Beyond the flagged items, the 2019 failure revealed a leaking offside front shock absorber that was contaminating the brake pad, disc, and tyre. That defect was not re-tested in 2021, so its resolution remains unconfirmed. A buyer should closely inspect the fork seals, check for oil misting on the stanchion, and verify the condition of the brake components. Given the four-year gap since the last test, a full assessment of tyre condition, brake fluid moisture content, chain and sprocket corrosion, and fuel system integrity is strongly advised before any road use.
