The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

UK

This 1999 Yamaha DT 125 R is a severe reliability concern: only 9.2% pass MOT first time against an 80% UK average, meaning nine out of ten fail their test. The dangerous defect rate of 1.2% is mercifully low, but the underlying problem—that nearly every bike needs work before it can pass—suggests these machines are either heavily worn, neglected, or both.

At 13,849 miles average, these aren't high-mileage machines, yet they're still failing at an extraordinary rate, which points to systemic issues rather than simple age-related wear. With only 0.11 failures and 0.4 advisories per vehicle on average, the data hints that problems cluster in a small number of bikes rather than affecting all equally—so if you're buying one, get a pre-purchase inspection done by a specialist mechanic, because this is genuinely a lottery.

MOT statistics not available

We have 402 1999 Yamaha Dt 125 R vehicles on record, but none have light-vehicle MOT history in our data source.

There are a few reasons this can happen:

  • Heavy commercial vehicle — trucks, buses and coaches over 3.5 tonnes are tested under the DVSA annual HGV/PSV regime, which uses a separate database not included in our data source
  • Imported vehicles — vehicles registered abroad and recently brought to the UK may have no UK MOT history yet
  • MOT-exempt — vehicles manufactured before 1986 qualify under the 40-year rolling exemption; some specialist and agricultural vehicles are also exempt
  • Never used on public roads — some vehicles are registered but kept off-road and have never required an MOT
