2012 Suzuki DL 650 AL1 0.6L Petrol · SP12 MME

The defining mechanical story for this DL650 is a repeating pattern of drive chain and braking component wear flagged across multiple consecutive tests, interspersed with two outright failures and several advisories. The most recent test on 17 September 2025 returned a pass but recorded a registration plate lamp defect, continuing a trend of minor lighting issues first noted at the 2022 failure and again at the 2023 retest. More significantly, the 2023 test produced two dangerous failures relating to the rear stop lamp and an excessively tight nearside rear drive chain, both of which represent immediate safety concerns. Across the recorded history there are advisories on the same rear brake hose, rear brake pads, a binding front brake, and repeated tension issues on the nearside rear drive chain, which collectively suggest chronic wear on consumable running gear and brake hydraulic components rather than an isolated incident. With 42,058 miles spread across approximately fourteen years, annual accumulation averages roughly 3,004 miles, which is low for a motorcycle of this type and suggests either modest seasonal use or extended periods off the road. The MOT history confirms annual testing from 2020 onwards with no multi-year gaps, indicating the vehicle has remained in use throughout this period despite the low annual mileage. Lower mileage accumulation typically reduces wear on internal drivetrain components such as the engine, gearbox and bearings, but it does not eliminate the need for regular chain adjustment, tyre replacement, brake fluid renewal and corrosion prevention on exposed steel components. The repeated chain tension advisories, in particular, are consistent with a machine that has been ridden regularly enough to need frequent adjustment, but the consistent annual testing pattern indicates the bike has not been left standing for prolonged periods. For a prospective buyer, the priority inspection areas should be the final drive chain and sprockets, as the nearside rear chain has been flagged as slightly tight or excessively tight across four separate tests between 2021 and 2023. On inspection, verify that the chain slack is within manufacturer specification at both the tightest and loosest points of swingarm travel, and check the rear sprocket teeth for hooking, shark-finning or uneven wear. The front brake was noted as binding in 2021, so during a test ride the front brake should be applied progressively from cold to confirm the caliper slides release cleanly without residual friction, and there should be no judder or pulsing through the lever that might indicate warped discs. The rear brake hose recorded ferrule corrosion in 2024, which warrants a close visual inspection of the unions for any seepage of brake fluid, and the caliper should be checked for seized pistons particularly given the rear pad advisory from 2022. On a test ride, listen for any metallic knocking or clonking from the rear suspension area over uneven surfaces, as worn swinging arm bearings or chain slider degradation can accompany chronic chain tension irregularities on this model. Confirm that both front and rear brake levers operate the corresponding stop lamp correctly, since the 2023 dangerous failure for the rear lamp on front brake application suggests a possible switch or wiring fault that may not have been fully resolved. The lighting defects at the registration plate lamp recorded in both 2022 and 2025 should be checked by operating all lighting positions and confirming every bulb or LED illuminates as designed. Finally, given the bike's age and low mileage, close attention should be paid to general corrosion on the swinging arm, subframe mounting points and any exposed steel fasteners, and the tyres should be inspected for cracking or hardening of the sidewalls as these can deteriorate with age even where tread depth remains adequate.
