2005 Yamaha FZ6 0.6L Petrol · RX55 AGV

The latest recorded DVSA MOT test took place on 14 April 2023, at which the vehicle was presented and passed, with two advisories raised against the final drive chain and rear sprocket. The previous test on 12 April 2022 also resulted in a pass, again with advisories regarding drive chain condition and, on that occasion, slight chain slack. Although the motorcycle has not failed an MOT in the available records, the recurrence of final-drive advisories across consecutive tests indicates a maintenance trend that is best described as gradually worsening rather than deteriorating rapidly. The progression from a slightly loose chain in 2022 to noted wear on both the chain and rear sprocket in 2023 suggests that the drivetrain is reaching the latter stage of its service life and should not be overlooked prior to purchase. The recorded mileage of 32,867 miles over approximately 21 years equates to an average annual usage of around 1,565 miles, which is notably low for a motorcycle of this age. This level of use suggests the vehicle has either been ridden relatively sparingly or has spent considerable periods standing, both of which carry their own mechanical implications. Low annual mileage does not necessarily equate to a well-preserved machine; prolonged standing can lead to corrosion of unmasked steel components, drying and cracking of rubber and elastomer parts, and degradation of lubricants and the battery, whereas genuine low use with regular servicing can be entirely benign. The relatively short interval between the two recorded tests is consistent with light, intermittent use rather than heavy commuting. Given the advisory history relating to the final drive, particular attention should be paid to the chain, both sprockets, and the chain slider during any physical inspection. The chain should be checked for uneven plating, stiff links, and inadequate slack, while the rear sprocket should be examined for hooked or asymmetrical teeth and the front sprocket for similar wear patterns. On a test ride, listen for any chatter or roughness from the transmission under load, and observe whether chain tension fluctuates excessively as the suspension works. Because the chain and sprocket set are now worn in tandem, it is strongly advisable to budget for a complete replacement chain and sprocket kit, which is the correct approach when one component of the set is at the end of its service life. In addition to the drivetrain concerns, the age and low usage profile of this motorcycle warrant a number of standing-related checks that may not be apparent from a brief viewing. The tyres should be examined closely for perishing or cracking of the sidewalls and tread, as rubber degrades with calendar age regardless of tread depth, and the date code on the sidewall should be reviewed to confirm they are within a safe service life. The brake discs should be inspected for surface corrosion and the calipers checked for free operation, as seized calipers are common on lightly used machines and can manifest as uneven braking or a dragging sensation. The 12 volt battery should be load tested if possible, as motorcycle batteries typically last only three to five years and may be near the end of their functional life. Finally, the brake fluid should be checked for moisture content and the brake hoses examined for surface cracking, as these items degrade with time rather than mileage, and confirmation of regular oil and filter changes, fork oil replacement, and coolant servicing would provide valuable reassurance that the machine has been correctly maintained throughout its standing periods.
