Should I check the MOT history before buying a 1992 Yamaha Tdm850?

The 1992 Yamaha TDM850 passes its MOT on the first attempt 81.8% of the time, marginally above the UK average of 80%, suggesting these older bikes are generally reliable workhorses—though the 12.9% that have recorded dangerous defects means you should ask for full service history and have any purchase inspected by a specialist. These machines have typically covered around 38,000 miles, which is reasonable for a 30-year-old motorcycle, and owners encounter an average of 1.45 failures per test and 5.4 advisories, pointing to minor wear items and maintenance rather than structural problems. Check the exhaust, electrics, and brakes carefully at purchase, as these are common advisory areas on aging bikes.
