# 1990 KAWASAKI KMX125-B4

The KMX125-B4 is a lightweight trail bike from the early 1990s, and it does not appear in the DVLA's light-vehicle MOT database—this cohort likely reflects a small sample of machines that have been registered on the road, or the data may be incomplete for this era and class. As a 125cc motorcycle, it would fall under different testing and classification rules than standard cars, and many such bikes are tested under separate regimes or have patchy historical records. What matters for a buyer is that these machines are now over 30 years old: at an average mileage of 22,659 and median of 18,676, they are relatively low-mileage survivors, often garage-kept classics or occasional-use machines rather than hard-worked commuters. If you're considering one, focus on frame condition, corrosion, and whether it has full service history, since parts availability and specialist servicing are the real concerns with a bike this old—not MOT pass rates.

MOT statistics not available

We have 278 1990 Kawasaki Kmx125 B4 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
