Should I check the MOT history before buying a 1998 Yamaha Yn50?

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 1998 Yamaha Yn50?

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 1998 Yamaha Yn50?

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 203 vehicles, the 1998 Yamaha Yn50 has a first-time MOT pass rate of 76.1%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

The 1998 Yamaha YN50 passes its MOT first time just 76.1% of the time, trailing the UK average of 80% and suggesting these 26-year-old scooters need more remedial work than typical vehicles. Dangerous defects show up in 13.8% of them—not extreme, but worth a pre-purchase inspection to verify brake and suspension integrity.

At nearly 9,800 miles average, these machines have seen typical use for their age, yet they're averaging 1.36 failures and 2.8 advisories per test, pointing to wear on consumables like tyres, controls and lighting rather than engine problems. If you're considering one, budget for a pre-MOT service and plan on replacing brake pads, cables and lights before the test—that'll significantly improve your chances of a clean pass.

We have limited data for the 1998 Yamaha Yn50 — treat the figures below as indicative rather than definitive.

What tends to go wrong

Across 203 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 27.8%

Rear Tyre worn close to the legal limit · Front Tyre worn close to the legal limit · Front Tyre valve stem slightly damaged · …

Brake wear 19.7%

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

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
