Should I check the MOT history before buying a 2008 Yamaha Xt 660 X?

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 2008 Yamaha Xt 660 X?

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 2008 Yamaha Xt 660 X?

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 2008 Yamaha Xt 660 X reliable?

Based on MOT data from 123 vehicles, the 2008 Yamaha Xt 660 X has a first-time MOT pass rate of 87.9%, 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 2008 Yamaha Xt 660 X?

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 2008 XT 660 X has a first-time MOT pass rate of just 59.4%, well below the UK average of 80%, which suggests these bikes accumulate meaningful wear issues by the time they reach test. The good news is that dangerous defects are relatively uncommon at 13.8%, so serious safety failures aren't the primary concern here.

The median mileage of 8,924 miles is quite low for a 16-year-old bike, indicating many examples have been lightly used or stored—yet they're still failing MOT at higher rates, pointing to corrosion, fuel system, and electrical gremlins rather than high-mileage fatigue. With an average of 0.94 failures and 3.2 advisories per test, expect minor repairs to be routine; budget for brake fluid checks, chain maintenance, and rust remediation before purchase, and have a pre-buy MOT inspection done by a specialist.

We have limited data for the 2008 Yamaha Xt 660 X — 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.
