2009 Yamaha YN 50 F Neos 0.0L Petrol · AG58 JNJ

Sporadic periods of inactivity define the mechanical history of this Yamaha Neos, which has transitioned from a phase of component failure in its early years to a more stable testing record. The vehicle passed its most recent inspection on 07 June 2025 with no defects recorded, continuing a trend of clean passes that began in 2018. While the current status appears clear, the historical record includes a 2017 failure for rough front wheel bearings and a 2014 failure involving exhaust deterioration and electrical lighting issues, indicating that the scooter has required specific interventions to maintain compliance over its seventeen-year lifespan. With a total of 11,589 miles recorded over seventeen years, the vehicle averages approximately 682 miles per annum. This low-mileage profile is punctuated by significant testing gaps, most notably between 2015 and 2017, and again between 2018 and 2024. Such extended periods of dormancy can lead to the degradation of rubber seals, the settling of fuel, and the potential for internal corrosion within the engine and transmission components. Prospective buyers should be aware that low mileage does not equate to a lack of wear, as short, infrequent trips often prevent the engine from reaching optimal operating temperatures, which can lead to carbon buildup and premature exhaust system degradation. During the test ride, pay particular attention to the front end, specifically the wheel bearings and steering head bearings. Given the 2017 failure for rough front wheel bearings, ensure there is no audible grumbling or vibration transmitted through the handlebars when rotating the wheel or navigating at low speeds. Any sensation of notchiness or resistance when turning the handlebars from lock to lock may suggest that the steering head bearings have suffered from lack of lubrication or ingress of moisture during the vehicle's long periods of storage. The braking system, which previously exhibited slight fluctuation in effort, should be evaluated for smooth engagement. Apply both the front and rear brakes firmly at low speeds to check for any pulsing or binding that might indicate warped discs or seized caliper pistons. Furthermore, verify that all electrical systems, including the stop lamps and headlamp dipped beam, function immediately upon activation, as these were specific points of failure in the vehicle's history. Inspect the exhaust system closely for signs of corrosion or patches, as the 2014 failure confirms this component is susceptible to deterioration, which can affect backpressure and engine performance.
