Should I check the MOT history before buying a 2004 Yamaha Yq100?

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 2004 Yamaha Yq100?

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 2004 Yamaha Yq100?

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.

Based on MOT data from 233 vehicles, the 2004 Yamaha Yq100 has a first-time MOT pass rate of 75.8%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

This 2004 Yamaha YQ100 falls slightly short of the UK average with a 75.8% first-time pass rate versus 80%, suggesting these scooters need a bit more attention than typical vehicles—though the 14.6% rate of dangerous defects isn't alarming enough to be a deal-breaker for most buyers. The median mileage of just 14,216 miles for a 20-year-old machine is remarkably low, hinting these are either garage queens or very lightly ridden, which actually works in your favour for finding a well-preserved example.

Averaging 1.61 failures and 3.3 advisories per MOT tells you these scooters tend to pick up minor wear issues rather than catastrophic problems, typical of older small-displacement machines. Before committing, get a pre-purchase inspection focused on the exhaust system and brake wear—the most common MOT culprits on aging scooters—and verify full service history to confirm the low mileage claim.

We have limited data for the 2004 Yamaha Yq100 — 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.

Brake wear 37.3%

Front Stop lamp does not illuminate immediately a brake applies · Front Brake pad(s) close to minimum limit · Front Brake pad(s) less than 1.5 mm thick · …

Usually cheap to fix. Worth confirming all lights work before collecting.

Exhaust & emissions 16.6%
