Moderate sample. 344 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2004 GSXR 600 has a first-time pass rate of just 37%, well below the UK average of 80%, which signals significant reliability concerns for a bike now 20 years old. The good news is that only 4.7% have suffered dangerous defects, so safety-critical failures are rare, but nearly two-thirds of these machines are failing their MOT on the first attempt.

With a median mileage of just over 10,500 miles, these bikes are lightly used for their age, yet they're still generating an average of 0.38 failures and 1.2 advisories per test—mainly suspension wear, lighting issues, and brake component deterioration typical of stored or neglected sportsbikes. If you're considering one, budget for pre-purchase inspection by a Suzuki specialist and expect remedial work on brake lines, tyres, and electrical components before it passes its next MOT.

The 2004 Suzuki Gsxr 600 K4 passes its MOT first time more often than most UK vehicles (86.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

For context
Good baseline reliability. A 86.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

These stats describe 344 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
