2001 Yamaha YN 100 0.1L Petrol · Y374 NFC

A history of intermittent failures and component degradation characterizes this vehicle, with the most recent recorded test on 31 January 2009 showing a pass with no defects. The earlier records from 2007 and 2008 reveal a pattern of mechanical issues involving lighting, braking systems, and suspension components. Specifically, the 2008 failure highlighted multiple critical faults including non-functional headlamps, a faulty brake stop lamp, excessively rough front wheel bearings, and an oil-leaking nearside front shock absorber seal. While the 2007 record noted a weak centre stand return spring alongside inadequate rear brake lever travel, the lack of subsequent testing data after early 2009 means the current state of these components cannot be verified through official records. The recorded mileage of 24,590 miles over a 25-year lifespan represents an exceptionally low annual average of approximately 984 miles. While this indicates minimal distance travelled, such low usage often correlates with long periods of stationary storage, which can impact the integrity of rubber seals, gaskets, and various fluid-based systems. The significant gap in MOT testing history following the 2009 pass suggests the vehicle has not been subject to official roadworthiness inspections for over seventeen years, making the current mechanical condition highly uncertain regardless of the low odometer reading. Prospective buyers should focus their physical inspection on the specific areas identified in previous failures to ensure they have not recurred or worsened during periods of inactivity. Given the 2008 failure regarding the nearside front shock absorber, a test ride should include checking for any visible oil misting on the fork legs or uneven damping. The previously noted rough front wheel bearings should be assessed by feeling for any vibration or notched sensation through the handlebars and listening for any humming or grinding noises while moving at speed. Braking performance must be scrutinised due to the historical issues with stop lamp illumination and inadequate brake lever travel. During a test, ensure the brake lever feels firm and provides sufficient modulation without excessive travel or a spongy sensation. The lighting system, particularly the dipped and main beams and the rear stop lamp, should be thoroughly tested for immediate and consistent operation. Additionally, the centre stand should be checked to ensure it retracts fully and holds its position, addressing the weak spring issue noted in the 2007 record.
