1991 Yamaha RD350 Ypvs 0.3L Petrol · J804 JCW

A 1991 Yamaha RD350 YPVS carrying four consecutive DVSA MOT test entries from 2022 through 2025 has produced a clean roadworthiness record, with all tests resulting in a pass and only one advisory issued across the entire documented history. That solitary advisory, recorded on 29 June 2023, noted a rear tyre worn close to the legal limit under Section 5.2.3 (e) of the inspection manual, a finding that was clearly addressed before the subsequent 2024 and 2025 tests, both of which returned with no defects recorded. The latest assessment on 12 June 2025 was again a clean pass, confirming a stable trend and demonstrating that the motorcycle has remained compliant with statutory testing requirements year on year. For a machine of this vintage, a record free from advisories relating to corrosion, structural integrity, lighting, or braking is notable, although it must be emphasised that MOT testing for motorcycles of this age evaluates only a defined subset of roadworthiness criteria. Against an age of approximately 35 years, the recorded mileage of 42,933 miles equates to an annual accumulation of roughly 1,227 miles, a figure considerably below what would be expected for a road-going motorcycle and consistent with either limited seasonal use, intermittent storage, or a combination of both. The relatively close spacing of the four MOT tests, all falling within a three-year window between 2022 and 2025, suggests the machine has been kept on the road and presented for testing regularly, with no extended gaps implying a long period off the road. Mechanically, this low-mileage profile carries specific implications for a two-stroke of this era, as prolonged standing periods can affect carburettor calibration, fuel system seals, two-stroke oil pump operation, and the condition of internal crankcase bearings that rely on regular oil circulation to remain free from corrosion. Even with no defects recorded under test, the buyer should be aware that low annual mileage on a 35-year-old two-stroke does not automatically equate to preserved mechanical health. Given the advisory concerning rear tyre wear in 2023, particular attention should be paid to the current rear tyre condition, including tread depth across the full width of the carcass, any flat spots indicative of prolonged standing, and the age of the rubber itself, as tyres fitted to low-mileage machines can harden and lose grip long before the legal tread limit is reached. On a test ride, listen for any binding or irregular feel from the rear brake, as calipers that have remained partially engaged during storage can cause noticeable pull or judder under braking. Check for signs of two-stroke oil residue around the crankcases, exhaust joints, and expansion chambers, which can point to deteriorating seals or failing crank bearings, both of which would be consistent with the age of the unit regardless of mileage. Finally, verify that the carburettors respond cleanly and synchronously to throttle inputs, as stale fuel residues in float bowls and pilot circuits are a common concern on machines that see only modest annual use, and confirm that the YPVS power valve system operates smoothly across the rev range without hesitation or irregular surging.
