Should I check the MOT history before buying a 2002 Yamaha Yn 100?

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.

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.

AI Analysis Reliability Overview Check a Specific Reg Buyer's Checklist Pass Rate by Fuel Mileage Distribution MOT Averages Compare Models

This 2002 Yamaha YN100 is a reliability concern: only 22.6% pass their MOT first time, versus the UK average of 80%, and nearly a quarter of these bikes have required repairs before passing. The good news is that dangerous defects are rare—just 1.7% of vehicles have ever had one—so safety-critical failures aren't the primary issue here.

At under 10,000 miles median mileage, these are lightly-used machines, yet they're still failing MOTs at an alarming rate, which suggests age-related decay rather than abuse or high miles. With an average of 0.25 failures and 0.4 advisories per vehicle, expect corroded electrics, perished seals, and fuel system problems typical of 20-year-old bikes that have sat idle. If you're considering one, budget for a pre-purchase inspection by a specialist mechanic—these aren't reliable commuters without serious recommissioning work.
