Should I check the MOT history before buying a 2002 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 2002 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.

How are tyres and brakes typically on a 2002 Yamaha Yn100?

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.

This 2002 Yamaha YN100 falls slightly below the UK average with a 77% first-time pass rate versus 80%, and nearly one in five have recorded a dangerous defect at some point, which warrants closer inspection on any used example you're considering. The median mileage of 7,268 miles is low for a 22-year-old machine, suggesting many have been gently used or stored, though the average failure rate of 1.71 per vehicle indicates these scooters do develop issues when tested.

With almost three advisories per vehicle on average, expect wear-related niggles rather than catastrophic problems—typical for an older commuter bike at this age. Before buying, have any prospect inspected by someone familiar with Yamaha scooters, and specifically ask for full service history to understand whether the low mileage reflects genuine light use or long periods of inactivity.

We have limited data for the 2002 Yamaha Yn100 — treat the figures below as indicative rather than definitive.
