Should I check the MOT history before buying a 2005 Yamaha Yfm 660?

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 2005 Yamaha Yfm 660?

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 2005 Yamaha Yfm 660?

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.

Is the 2005 Yamaha Yfm 660 reliable?

Based on MOT data from 249 vehicles, the 2005 Yamaha Yfm 660 has a first-time MOT pass rate of 85.7%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2005 Yamaha Yfm 660?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

This 2005 Yamaha YFM 660 is a significantly weaker performer than the UK average, with a 59.9% first-time pass rate sitting well below the 80% national benchmark—meaning nearly 4 in 10 fail their MOT. The 13.7% dangerous defect rate is a notable concern and higher than you'd typically see, suggesting potential safety issues that need careful attention before purchase.

These quads are averaging 3,020 miles despite their age, which isn't unusually high for a machine of this type, but the 0.86 failures and 2.9 advisories per vehicle indicate persistent mechanical wear. If you're considering one, budget for repairs and have any prospective purchase inspected by someone who knows these machines well, particularly around the areas flagged as dangerous defects.
