Should I check the MOT history before buying a 2004 Hyosung GT 125 Comet?

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 Hyosung GT 125 Comet?

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 Hyosung GT 125 Comet?

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 2004 Hyosung GT 125 Comet reliable?

Based on MOT data from 122 vehicles, the 2004 Hyosung GT 125 Comet has a first-time MOT pass rate of 73%, 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 2004 Hyosung GT 125 Comet?

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 2004 Hyosung GT 125 Comet is a genuine reliability concern: only 45.5% pass first time against the UK average of 80%, meaning buyers should expect serious repair bills before getting one through MOT. Nearly 15% of these bikes have recorded dangerous defects, which is a meaningful safety risk on a 20-year-old machine.

At just over 16,000 miles on average, these are relatively low-mileage examples for their age, yet they're still failing at nearly double the typical rate—suggesting design or build quality issues rather than wear and tear. With 1.34 failures and 4.6 advisories per vehicle, budget for persistent mechanical problems, and always have a pre-purchase inspection by a specialist in older Asian sports bikes before committing.

We have limited data for the 2004 Hyosung GT 125 Comet — treat the figures below as indicative rather than definitive.
