Should I check the MOT history before buying a 2004 Suzuki Gsf 600 Sk4?

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 Suzuki Gsf 600 Sk4?

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 Suzuki Gsf 600 Sk4?

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 Suzuki Gsf 600 Sk4 reliable?

Based on MOT data from 113 vehicles, the 2004 Suzuki Gsf 600 Sk4 has a first-time MOT pass rate of 86.4%, 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 Suzuki Gsf 600 Sk4?

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 2004 Suzuki GSF 600 SK4 is a real concern on the MOT bench: just 49.5% pass first time, nearly 31 percentage points below the UK average of 80%. While dangerous defects are relatively uncommon at 7.1%, the consistently poor pass rate suggests systemic maintenance issues across this cohort.

These bikes are running low mileage for their age (median 14,694 miles), which paradoxically often correlates with neglect rather than careful stewardship—and the numbers bear that out, with an average of 0.65 failures and 2.4 advisories per test indicating accumulated wear and deterioration from standing. If you're considering one, budget for a full pre-purchase inspection and expect to address multiple defects before it'll pass its next MOT.

We have limited data for the 2004 Suzuki Gsf 600 Sk4 — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 20 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.
