The 1999 Honda ST1100 passes its MOT first time at 82.4%, which is slightly above the UK average of 80%—a solid result for a 25-year-old machine. However, nearly a quarter of these bikes (22.9%) have recorded a dangerous defect at some point, which is a legitimate concern for any prospective buyer and warrants a thorough pre-purchase inspection.

With a median mileage of 45,302 miles for a model this age, these are relatively low-mileage examples, suggesting many have been cherished rather than worked hard. The average of 1.59 failures per test and 6.3 advisories tells you these are aging machines with accumulated wear, so budget for maintenance items and always get a full mechanical check before committing to a purchase.

The 1999 Honda St1100 passes its MOT first time at roughly the UK average rate (87.5%) — 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

✅ Good baseline reliability. A 87.5% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 6.3 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 878 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.
