Should I check the MOT history before buying a 1998 Yamaha Xj900?

The 1998 Yamaha XJ900 passes its MOT on the first attempt 84.7% of the time, which is comfortably above the UK average of 80%, suggesting these bikes are generally well-maintained. However, 20% have recorded a dangerous defect at some point, which is a meaningful safety concern worth investigating on any used example you're considering.

At 26 years old, these machines typically show around 33,700 miles on the clock—reasonable mileage for their age—but they average 1.85 failures and 7.1 advisories per test, indicating that while major issues are relatively uncommon, minor wear and accumulated niggles are the norm. Before buying, have a pre-purchase inspection specifically check the brake system and suspension, as these are where the failures are concentrated on aging bikes of this generation.

The 1998 Yamaha Xj900 passes its MOT first time at roughly the UK average rate (84.7%) — solid but worth checking this vehicle's history carefully.

⚠️ Over 1 in 5 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.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 7.1 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 515 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
