The 1981 Yamaha SR250 passes its MOT first time in 83.4% of cases, which is a solid 3.4 percentage points above the UK average and suggests these machines are holding up reasonably well. The dangerous defect rate of 8.2% is mercifully low, so major safety issues are uncommon.

At an average mileage of 25,231 miles for a 43-year-old bike, these are being ridden regularly rather than mothballed, which makes the pass rate more impressive. With an average of 1.05 failures per vehicle and 3.5 advisories, expect minor wear items to crop up—typical of classic bikes—but nothing alarming; if you're considering one, get a pre-purchase inspection to flag any hidden corrosion or fuel system problems before committing.
