The 1999 Yamaha XJ600 passes its MOT just above the UK average at 82.4%, which is solid, but nearly a quarter of these bikes (22.6%) have recorded a dangerous defect at some point—a genuine buyer concern worth investigating on any used example you're considering. With an average of 2.06 failures per vehicle and 7.0 advisories, these machines aren't troublesome, but they do need attention to stay roadworthy.

At 24,483 miles average for a 25-year-old bike, these are typically well-used machines, yet they're holding up reasonably well mechanically. Before buying, have a pre-purchase inspection done by a specialist mechanic, and ask the seller specifically about the service history—this model rewards consistent maintenance and will likely cost you more to fix if neglected.

The 1999 Yamaha Xj600 passes its MOT first time at roughly the UK average rate (82.4%) — 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 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 845 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.
