1979 Honda CB900 0.9L Petrol · GGJ 720T

The most recent MOT test on 13 October 2022 resulted in a pass with no defects recorded. Looking back through the history to 2016, the maintenance trend is exceptionally stable, showing a consistent pattern of clean passes. Aside from a single failure in 2016 regarding rear tyre tread depth, there have been no recorded advisories or defects for several years, which indicates a vehicle that has been meticulously maintained or kept in a preserved condition. The recorded mileage of 16,869 miles is remarkably low for a vehicle of this vintage, averaging approximately 359 miles per year over its 47 year lifespan. While this suggests minimal wear on the internal engine components and the gearbox, such low annual usage often implies long periods of inactivity. This pattern of standing can be more detrimental to certain components than regular use, as it leads to the degradation of seals, the accumulation of moisture in fluids, and the potential for stagnation in the fuel system. Given the lack of recent defects and the low usage profile, the prospective buyer should focus on time based degradation rather than wear based failure. It is critical to inspect the tyre sidewalls for signs of perishing or weather cracking, as rubber hardens and loses grip over time regardless of remaining tread depth. The braking system requires close scrutiny for binding calipers or surface corrosion on the brake discs, which are common symptoms of a vehicle that has stood for extended periods. A thorough check of the 12V battery health and the charging system is also advised to ensure the vehicle starts and runs reliably. Further attention should be paid to the fluid integrity and rubber components. The buyer should verify when the engine oil and brake fluid were last replaced, as these fluids degrade over time due to oxidation and moisture absorption. Inspect the fuel lines and carburettors for signs of varnish or gumming caused by old fuel, and check all rubber boots and hoses for splitting or shrinkage. Finally, a review of the service book stamps is essential to confirm that the vehicle has received calendar based maintenance even during periods of low mileage to ensure long term mechanical reliability.
