2017 Triumph Bonneville 1.2L Petrol · WF17 KYJ

The Triumph Bonneville presents a flawless MOT record with no defects, advisories, or failures recorded across five consecutive annual tests. The most recent examination on 18 April 2026 at 20,383 miles resulted in a completely clean pass, indicating the motorcycle currently meets all DVSA roadworthiness standards with no outstanding mechanical or structural concerns. The maintenance trend is demonstrably stable, with no recurring faults or emerging deterioration patterns evident in the official record. The mileage profile tells a consistent story of gentle, regular use. Annual increments between tests range from approximately 1,392 miles to 2,235 miles, with the vehicle covering roughly 2,265 miles per year on average over its nine-year life. This is notably low for a machine of this age. The steady accumulation between each April test suggests the motorcycle has been ridden consistently rather than left standing for extended periods, which is a positive indicator for the condition of seals, fuel system components, and tyres. There are no anomalous gaps or sudden jumps in recorded mileage that would raise concern about odometer tampering or prolonged inactivity. Despite the clean MOT history, the low annual mileage warrants a focused physical inspection of components that degrade with time rather than use. The original tyres, dating from 2017, will almost certainly require replacement regardless of remaining tread depth due to age-related rubber deterioration, cracking, and reduced grip. Brake fluid should be checked for moisture absorption, as infrequent riding promotes condensation buildup that degrades braking performance and corrodes internal caliper components. Chain and sprocket condition deserves close scrutiny, as a poorly maintained chain on a low-mileage machine can still suffer from corrosion and stiff links caused by infrequent lubrication during periods of light use. The suspension, steering head bearings, and swingarm pivot should be inspected for free play and smooth operation, since a motorcycle covering fewer than 2,300 miles annually may develop brinelling or dried grease in bearings rather than classical wear. Fuel system integrity, including fuel lines and the condition of the tank interior, is worth verifying given the age of the machine and the potential for ethanol-related degradation in modern petrol. A test ride will confirm smooth clutch operation, gearbox precision, and the absence of any exhaust blow-by or oil seepage that a stationary inspection might miss.
