Should I check the MOT history before buying a 2005 Suzuki Gn125?

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.

The 2005 Suzuki GN125 passes first time just under the UK average at 79%, but nearly a quarter of the bikes tested have recorded a dangerous defect at some point, which is a genuine concern for safety-critical systems. Petrol versus diesel isn't relevant here, so the middling pass rate is the main reliability flag.

These machines average just over 14,000 miles, which is quite low for a 19-year-old bike and suggests many have been lightly used or stored—a positive sign for wear. With 2.17 failures and 6.2 advisories per vehicle on average, you're looking at recurring minor issues rather than catastrophic failures, but before buying one, get a full independent inspection focused on brakes, lights, and suspension to rule out that dangerous defect risk.

We have limited data for the 2005 Suzuki Gn125 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 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.

What tends to go wrong

Across 216 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Lighting 65.1%

Drive chain slightly loose · Rear Drive chain sprocket slightly worn · Headlamp aim too high · …

Usually cheap to fix. Worth confirming all lights work before collecting.

Tyre wear 54.5%

Rear Tyre worn close to the legal limit · Rear Tyre tread depth is below minimum requirements of 1.0mm · Front Tyre worn close to the legal limit

Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.

Other issues 47.7%

Drive chain worn but not considered excessive · Drive chain excessively loose · Drive chain worn to excess

Brake wear 12.3%

Front Brake lever is bent but brake can still be readily applied

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.

Suspension & steering 11.5%

Steering movement slightly 'notchy'

Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
