The 1999 Yamaha TDM850 passes its MOT first time at 87.3%, which is comfortably above the UK average of 80%, suggesting these machines are generally well-maintained and reliable. A dangerous defect rate of 14.7% is moderate and not a major concern, though it's worth having a pre-purchase inspection focus on brake and suspension systems.
At nearly 27,000 miles on average, these bikes have covered reasonable distances for their age, and the 1.67 failures per vehicle indicates most issues are minor and fixable. The high advisory count of 6.9 per bike points to the wear you'd expect from a 25-year-old motorcycle—check lighting, cables, and exhaust condition carefully before buying, and budget for consumables in your first year.
