Should I check the MOT history before buying a 2004 Yamaha Bt1100?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

The 2004 Yamaha BT1100 passes first time at 88.2%, meaningfully better than the UK average of 80%, which is a solid endorsement of its baseline reliability—though the concerning figure here is that 22.3% of these bikes have recorded dangerous defects, putting safety concerns on the buyer's radar. Petrol motorcycles inherently wear differently than cars, and this model's 1.59 average failures per test suggests structural issues crop up once problems begin.

These machines average 16,900 miles with a median of 13,645, indicating moderate use for a nearly 20-year-old bike, so age rather than hammering is the typical wear story. The 5.6 average advisories per vehicle reveal that while major failures are relatively uncommon, minor maintenance gaps and ageing components are routine—so budget for consumables and get a pre-purchase inspection focused on the fuel system, electrics, and brake condition before committing.

We have limited data for the 2004 Yamaha Bt1100 — treat the figures below as indicative rather than definitive.

⚠️ 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.
