Should I check the MOT history before buying a 1998 Yamaha Xj 600 S Diversion?

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 Xj 600 S Diversion?

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 Xj 600 S Diversion?

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 1998 Yamaha Xj 600 S Diversion reliable?

Based on MOT data from 181 vehicles, the 1998 Yamaha Xj 600 S Diversion has a first-time MOT pass rate of 83.6%, 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 1998 Yamaha Xj 600 S Diversion?

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.

The 1998 Yamaha XJ 600 S Diversion has a first-time MOT pass rate of just 34.7%, less than half the UK average of 80%, signalling that age and condition are working against these bikes. With only 3.9% recorded dangerous defects, safety isn't the primary concern—instead, this is a machine that needs work to meet emissions and wear thresholds.

At a median mileage of 27,796 for a 26-year-old bike, these examples have been ridden moderately but have likely spent time in storage or seen inconsistent maintenance. The average of 0.35 failures and 1.3 advisories per vehicle suggests common niggles rather than catastrophic problems, but any buyer should budget for sorting brakes, lights, and exhaust systems before passing the test.
