2017 Yamaha MT-10 SP MTN1000D 1.0L Petrol · AX17 CKF

The most recent DVSA test recorded on 13 May 2026 resulted in a Pass with no advisories, although notably the same date also shows a Fail with a Major defect for an excessively loose drive chain. The combination suggests the chain adjustment or replacement was carried out and a re-test was immediately recorded. Looking at the broader trend, the vehicle has accumulated defects over successive tests that point to consumables and chassis wear being addressed reactively rather than preventatively. The 2025 test recorded a Major failure for excessive play in the front wheel bearing alongside an advisory for rear brake pads approaching minimum thickness, and the 2023 test flagged a worn drive chain and rusty front brake pads. The trajectory is one of a machine that is generally being kept roadworthy but showing classic wear progression in the drive line, braking system, and front wheel components. Against a calendar age of approximately nine years, the recorded 38,880 miles equates to a very modest annual average of around 4,320 miles, which is low for any motorcycle and particularly for a high-performance naked machine such as the MT-10 SP. There are noticeable gaps in the MOT history, with tests recorded in 2021 and 2020 but none in 2022, suggesting either a period off the road or simply test inactivity. Low annual mileage of this nature typically implies extended periods of standing, which carries well-documented consequences for battery state of charge, brake disc surface corrosion, hydraulic fluid ageing, internal corrosion of the exhaust system, and potential drying or perishing of rubber components such as fork seals and suspension bushes. Given the recurring drive chain advisories and the failure for excessive chain slack, a prospective purchaser should closely inspect the chain, sprocket, and countershaft sprocket for elongation of the sprocket teeth, uneven wear patterns, and adequate remaining adjustment range within the swingarm. If adjustment is already at or near its limit, a chain and sprocket replacement should be budgeted for. On a test ride, listen for chain slap under deceleration, watch for missed engagement on the rear sprocket, and feel for any jerking under steady throttle which could indicate worn or stiff chain links. The 2025 advisory for rear brake pads being close to minimum limit means they have likely now been renewed, but the caliper should be checked for free operation, the slider pins for seizing, and the rear disc for lip formation or hot spots. The front wheel bearing failure is a serious safety item; after replacement the new bearing should be checked for play, and the front brake disc inspected for warping which can present as a pulsing or shuddering sensation under heavy braking. Beyond the documented defects, the low usage profile warrants a thorough standing-age inspection. The 12V battery should be load-tested, as a nine-year-old battery or one that has sat discharged will almost certainly require replacement. Brake discs, particularly the front, should be examined for severe surface rust or pitting which may necessitate machining or replacement if deep enough to affect braking efficiency. Tyres, despite possibly having ample tread due to low mileage, must be inspected for sidewall cracking and perishing caused by age, as rubber compounds degrade with time regardless of wear; the DOT stamp should be checked, and any tyre over five or six years old considered for replacement. All fluids, including engine oil, coolant, brake fluid, and clutch hydraulic fluid, should be treated as time-expired and renewed as part of the purchase, as brake fluid in particular is hygroscopic and will have absorbed moisture over nine years. Finally, verify the service book stamps and ensure the valve clearance inspection and spark light renewal have been carried out at the manufacturer-recommended intervals, as these are particularly important on the CP4 cross-plane engine.
