2013 Triumph Tiger 1.1L Petrol · LC13 DTO

The most recent DVSA examination on 11 March 2026 resulted in a pass, accompanied by an advisory for an oil leak, which mirrors a near-identical advisory recorded at the previous test on 15 March 2025 relating to the nearside lower oil leak. The continuity of this defect across two consecutive tests indicates that the leak has not been rectified between examinations and warrants close attention. Aside from this recurring advisory, the vehicle has demonstrated a largely stable maintenance trajectory in recent years, with passes recorded in 2024, 2022, and 2020 free of any recorded defects. The earlier failure of 15 January 2022 was addressed promptly at the subsequent re-test on 29 January 2022, which produced a clean pass, suggesting that the owner has generally maintained the motorcycle to a satisfactory standard, although the unresolved oil leak represents an ongoing concern that should not be overlooked. With an accumulated mileage of 37,043 miles over approximately thirteen years, this Triumph Tiger has averaged around 2,849 miles annually, which is notably low for a motorcycle of this vintage and suggests either limited recreational use or extended intervals of standing. Low annual mileage of this nature carries distinct mechanical implications, particularly in relation to calendar-based component degradation rather than wear through distance. Long periods of inactivity can promote moisture accumulation within the fuel system, oxidation inside the engine and gearbox, surface corrosion on brake discs and calipers, and premature ageing of rubber components throughout the chassis and drivetrain. Conversely, the drivetrain and consumables are unlikely to have suffered extensive wear from sustained high-mileage use. The recurring oil leak advisory merits particular scrutiny during a pre-purchase inspection. The prospective buyer should identify whether the leak originates from the engine casings, sump gasket, cam cover gasket, or a higher engine joint, as the location will dictate both repair complexity and the risk of progressive oil loss leading to component damage. During a test ride, the engine should be observed for any smoke from the exhaust upon start-up, and the underside of the engine and surrounding frame areas should be examined for fresh oil residue or wet accumulation that would confirm an active leak rather than a historical staining. Given that the advisory has been repeated across consecutive tests, the cost of rectification should be factored into any negotiation, and a compression test may be prudent to verify internal engine health if the leak is severe. Additionally, the front brake disc, caliper, and pad condition should be inspected carefully, as the 2022 failure recorded front brake pads below 1.0 mm thickness and the 2019 test recorded an advisory for nearside front inner brake pads approaching the minimum limit, indicating that the front braking system has historically experienced accelerated wear and would benefit from close inspection for disc lipping, pad material remaining, and caliper slide pin freedom. Given the low recorded mileage and the age of the motorcycle, the buyer should prioritise checks associated with time-related degradation rather than distance-based wear. The tyres, despite potentially retaining legal tread depth given the low mileage, should be examined for sidewall perishing, cracking, and weather checking consistent with thirteen years of UV exposure and ageing rubber compounds, which can compromise integrity regardless of remaining tread. The 12-volt battery should be load-tested or replaced prophylactically, as batteries of this age frequently fail without warning and can cause starting difficulties and electrical faults. Brake discs should be inspected for standing corrosion, particularly on the edges of the front disc where rust pitting can occur from infrequent use, and the calipers should be checked for freedom of movement and seized pistons, which are common after prolonged standing. Drive chain and sprocket condition warrants close attention in light of the chain looseness recorded at both the 2023 and 2019 tests, with the buyer checking for tight spots, excessive slack, stiff links, and worn sprocket teeth. Finally, all service items should be confirmed as current, including engine oil and filter, brake fluid, coolant, and fork oil, as low annual mileage does not prevent the degradation of these fluids over time, and verifying the service book stamps and history will provide assurance that calendar-based servicing has been diligently observed.
