2018 KTM 300 EXC SIX Days TPI 18 0.3L Petrol · WM67 RCX

A recurring mechanical theme runs through the recorded DVSA history of this 2018 KTM 300 EXC SIX DAYS TPI, centred on the rear wheel bearing. Slight play in that bearing was flagged as an advisory at the 2022 MOT and was repeated as an advisory at the 2023 MOT, indicating a persistent rather than resolved issue across a near two-year span. The intervening test on 18 March 2026 produced a clean pass with no advisories or defects recorded, which is positive on the surface but means the bearing status is now unverified rather than confirmed remedied. Given the duplication of the same advisory across consecutive tests, a prospective buyer should treat the rear wheel bearing as a live concern that may have finally progressed beyond a minor advisory threshold, or alternatively been replaced without being captured in the MOT record. The recorded mileage data is insufficient to calculate a meaningful annual accumulation rate or to identify any unusual gaps or sharp increases in usage. What can be observed is the testing cadence itself, with entries in March 2022, October 2023, and March 2026, showing an irregular pattern of MOT submission rather than a continuous annual testing sequence. For an enduro machine of this type, where usage is likely to be seasonal and tied to off-road riding conditions, this irregularity is not necessarily concerning from a mechanical standpoint, but it does mean that the vehicle has spent appreciable periods off the public road and therefore uninspected by DVSA. Any mechanical degradation occurring during those lay-up periods would not be reflected in the available record. Given the duplicated rear wheel bearing advisories, particular attention should be paid to the bearing condition during a physical inspection. Symptoms to look for include lateral movement or rocking at the rear wheel when it is lifted off the ground, any roughness or notching as the wheel is rotated by hand, and grease contamination around the bearing seals or on the rear hub. On a test ride, any humming, grinding, or rumble that rises and falls with road speed, or a slight wander from the rear end, would suggest the bearing play has progressed. Given the off-road intended use of this model, it is also worth checking for water ingress damage or impact-related distress to the bearing, both of which can accelerate wear. The brake-related advisories, which appeared on the front in 2022 and on the rear in 2023, suggest that pad wear is being monitored but has not yet reached a failure threshold. On inspection, the remaining friction material thickness on both front and rear pads should be measured, and the corresponding discs checked for scoring, warping, or excessive wear, particularly the rear disc given the near-limit pad advisory. As this is a two-stroke enduro platform with TPI fuel injection, any test ride should also be used to listen for unusual engine noises, check for oil leaks around the lower frame and suspension linkages, and confirm smooth clutch action. The absence of a recorded mileage history and the irregular testing pattern mean a pre-purchase inspection by a specialist familiar with KTM off-road machinery would be prudent to supplement the MOT data.
