2018 Harley-Davidson Flsl Softail Slim 1745 18 1.7L Petrol · CH17 ALK

A pattern of unblemished roadworthiness defines this 2018 Harley-Davidson FLSL Softail Slim, with five consecutive MOT passes logged between 2022 and 2026 and not a single advisory or failure recorded across that span. The most recent test on 3 September 2026 was a clean pass with no defects noted, reinforcing a trend of consistent compliance rather than a gradual decline or sudden improvement. The complete absence of recorded advisories means there is no MOT-derived evidence of component wear, corrosion, or deterioration in any testable area, which is notable for a motorcycle of this vintage. The mechanical picture drawn from official testing is therefore one of stability and absence of flagged concerns, though the test record alone does not validate the condition of items that fall outside the MOT scope. With 9,556 miles recorded against an age of roughly eight years, this machine has averaged around 1,194 miles annually, which sits firmly in low-mileage territory for a motorcycle. Such modest accumulation can reflect occasional leisure use, seasonal riding, or extended periods of storage, and the absence of any recorded testing gaps suggests the vehicle has remained on the road continuously rather than being SORNed for multi-year stretches. Mechanically, low annual mileage on a big-twin Harley tends to place greater stress on certain consumables through standing rather than wear: oil seals, gaskets, and rubber components can harden or weep from prolonged inactivity, brake discs and pads can suffer surface corrosion even when pad material remains generous, and battery health can deteriorate without regular charging cycles. The 1745cc V-twin drivetrain itself is unlikely to have accrued significant internal wear at this mileage, but the peripheral systems benefit from closer inspection than the MOT record can provide. For a prospective buyer, a focused physical inspection should target the areas most likely to betray low-mileage storage rather than active service. Check the underside of the engine and primary cover for any oil misting or weeping from the gaskets, rocker box seals, and the classic Softail area around the compensator and front of the crankcase, as a slow seep can develop from temperature cycling rather than high mileage. Examine both front and rear brake discs for lipping and surface rust scoring, and confirm the calipers release cleanly without binding, as seized caliper pistons are a common storage-related issue on low-use bikes. Inspect the tyres carefully for sidewall cracking, flat-spotting from stationary loading, and check the production date, because rubber compounds perish with age regardless of tread depth. Finally, confirm the battery holds charge under cranking load and ask for evidence of recent servicing, particularly oil and filter changes, as low mileage does not exempt a Harley big-twin from annual fluid maintenance. On a test ride, listen specifically for any clonking or knocking from the rear suspension linkage and check the Softail monoshock for smooth damping without harshness, as the hidden shock is not directly examined at MOT but can deteriorate from disuse. Feel for any vibration through the handlebars that suggests worn headstock bearings, and confirm the steering moves freely without notches. Test the brakes progressively from low speed to higher speed to ensure there is no judder or pull indicating warped discs, and verify the gear change is positive and clutch engagement is clean without slipping under load. Any misfire, rough idle, or difficulty starting from cold would warrant closer scrutiny of the fuel system and ignition components, given the bike's low annual use, while a clean cold start and steady running would strongly corroborate the fault-free MOT history on record.
