2012 Royal Enfield Bullet Classic EFI 0.5L Petrol · AE12 BZF

The most recent MOT on 2022-04-11 shows a failure with critical issues: a major exhaust leak, an insecure lambda sensor, and a rider’s seat bolt that was not properly tightened. These defects pose safety risks, particularly the exhaust leak, which could affect engine performance and emissions, and the loose seat bolt, which might compromise rider stability. A separate pass on the same date noted the same fuel hose damage (perished and cracking) but no other issues. This inconsistency suggests possible incomplete repairs or conflicting test outcomes. Recurring issues include fuel hose degradation (perished and cracking), first recorded in 2022 and likely present earlier. This indicates potential neglect or exposure to harsh conditions, as fuel hoses degrade over time regardless of mileage. The exhaust system and lambda sensor failures in 2022 highlight a more severe mechanical concern, possibly linked to age-related wear or improper maintenance. No other major defects were recorded in earlier MOTs (2018–2021), suggesting the vehicle was previously well-maintained. The trend appears to be worsening since 2022, with more serious issues emerging compared to earlier years. However, the low mileage (7,263 miles over 14 years, ~519 miles/year) complicates interpretation.
