Should I check the MOT history before buying a 2001 Yamaha Yn100?

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.

What corrosion should I look for when inspecting a 2001 Yamaha Yn100?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2001 Yamaha YN100 passes its MOT just below the UK average at 78.4%, suggesting slightly more wear than typical for its age, though the 15.9% rate of dangerous defects isn't alarming for a 20-year-old scooter. Petrol versus diesel comparisons don't apply here since this is a petrol-only 100cc commuter bike.

These machines have covered modest mileage—a median of just under 8,000 miles—which hints at light use over two decades, yet they still average 1.49 failures and 2.9 advisories per test, pointing to age-related deterioration rather than hard work. Check the condition of the fuel system, electrics, and tyres closely on any example you're considering, and budget for routine maintenance to keep one roadworthy.

We have limited data for the 2001 Yamaha Yn100 — 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.
