Should I check the MOT history before buying a 1990 Yamaha Rxs100?

The 1990 Yamaha RXS100 has a first-time MOT pass rate of 76%, slightly below the UK average of 80%, which suggests these bikes are a bit more prone to minor issues than the typical vehicle. The dangerous defect rate of 16.3% is reasonably low, so structural or safety problems aren't a major concern with this model.

Most examples are running around 25,000 miles on average—quite moderate for a 30-plus-year-old bike—and tend to pick up an average of 1.38 failures and 2.9 advisories per test, pointing to gradual wear rather than catastrophic problems. When shopping for one, budget for routine work on small components and fluids, but these machines have proven they can soldier on; check the service history and have a pre-purchase inspection focus on the fuel system and electrics, which are common weak points on classics of this era.

We have limited data for the 1990 Yamaha Rxs100 — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
