2015 Honda CBR 0.6L Petrol · ST64 NFZ

A motorcycle of this vintage showing only three recorded MOT tests over a decade, with the most recent DVSA examination on 17 August 2023 returning a pass but flagging a brake effort fluctuation, presents a usage profile that is far more relevant than the test outcome itself. The single advisory relating to front brake effort fluctuation under the 1.2.1 (e) category is a comparatively minor entry on a motorcycle of this age, and the two prior tests in May 2022 and September 2019 recorded no defects at all. However, the sparsity of the testing record means there are large unverified intervals, and the front brake system noted in 2023 has had no subsequent MOT to confirm whether the fluctuation has progressed, stabilised, or been rectified. The overall pattern is one of largely clean roadworthiness on the limited occasions the bike has been presented, but with too little recent data to call the trend stable. The recorded mileage of just 124 miles across an eleven-year vehicle life equates to roughly 11 miles per year on average, which is exceptionally low for any motorcycle, particularly a sports-oriented machine such as the CBR. Such minimal usage raises legitimate concerns about the mechanical condition of components that suffer from prolonged standing rather than active wear. Brake calipers, particularly on a front assembly that has already shown effort fluctuation, are prone to piston seizure when stationary for extended periods, and flexible brake lines can degrade internally even without mileage accumulation. The fuel system, battery, drive chain, and clutch plates on a low-use motorcycle of this age are all candidates for deterioration through lack of operation rather than wear. Equally, the substantial gaps between tests — for example, the absence of any recorded MOT between September 2019 and May 2022 — suggest periods where the bike was either off the road, exempt, or simply not used, and these dormant intervals are themselves relevant to the assessment. A prospective buyer should pay close attention to the front brake system flagged in the 2023 advisory. On a test ride, the front lever should feel firm and progressive; any sponginess, uneven pull, or a lever that travels further than expected under repeated application would suggest caliper binding or hydraulic issues consistent with the recorded fluctuation. With the bike off the centre stand and on level ground, the front disc should rotate freely without resistance or scraping, and the calipers should not appear to be gripping when the lever is released. Given the very low mileage, the brake fluid itself should be inspected for age-related degradation, and any visible moisture or discolouration noted, as fluid left undisturbed for years will have absorbed moisture regardless of how few miles the bike has covered. Beyond the brakes, the rest of the inspection should focus on the consequences of long-term standing rather than mileage accumulation. The battery should be load-tested or at minimum checked for cranking speed, as a chronically discharged or sulfated unit is common on a motorcycle of this usage profile. The drive chain and sprockets should be examined for surface corrosion and stiffness, and the chain should be checked for free movement at the rear sprocket area, as even a thin layer of rust from disuse can cause tight links and premature wear once the bike is ridden again. Tyres manufactured more than a few years ago will have hardened and lost grip regardless of tread depth, and the sidewalls should be checked for cracking. Finally, all fluids should be verified for condition and age rather than assumed serviceable based on the MOT record alone, as MOT testing does not cover the freshness of oil, coolant, or hydraulic fluid, all of which are critical on a motorcycle that has clearly spent the majority of its life stationary.
