2010 Triumph Sprint 1.1L Petrol · OU59 FMC

A recurring drive‑chain slack advisory defines the mechanical narrative of this 2010 Triumph Sprint; the chain was flagged as slightly loose in both the 2022‑05‑30 and 2023‑04‑22 MOTs, yet the vehicle has cleared every subsequent test, including the most recent 2026‑05‑09 inspection, without further defects. The pattern suggests a persistent adjustment issue rather than a sudden failure, and the absence of new failures indicates that the problem has not escalated in the past three years. With only 20,233 mi recorded over sixteen years the annual accumulation averages roughly 1,260 mi, well below typical usage for a sport‑bike of this age. Such low mileage often points to prolonged periods of inactivity, which can allow components such as rubber hoses, seals and the drive chain to stiffen or settle. While the mileage itself reduces wear on consumables, the extended idle intervals may have contributed to the chain slack noted in the MOTs, and could also predispose ageing elastomers to cracking. Prospective buyers should give the drive chain immediate attention during a test ride. Listen for a faint rattle or metallic clatter at low to moderate revs, feel for any excess play when the rear wheel is turned by hand, and inspect the chain tensioner for proper positioning and wear. Examine the sprockets for uneven tooth wear or glazing, and verify that the chain is adequately lubricated and free of oil ingress, as excess oil can accelerate wear and exacerbate slack. Any noticeable increase in chain noise, sudden jumps in rear wheel speed, or difficulty maintaining a steady throttle could indicate that the chain tension is beyond the advisory level and may require adjustment or replacement. Beyond the chain, a comprehensive pre‑purchase inspection should confirm the condition of the surrounding drivetrain bearings, rear suspension bushes and linkage points, and the frame for any hidden corrosion that the MOT would not capture. Given the low mileage, pay particular attention to the integrity of rubber components such as fuel lines, coolant hoses and boot seals, looking for cracks or brittleness. While the MOT history shows no outright failures, the combination of low usage and the recurring chain advisory makes a focused evaluation of these areas essential before committing to purchase.
