The 1999 Kawasaki GPZ500S passes its MOT slightly above the UK average at 82.8%, which is reassuring, though one in six examples (17.5%) have recorded a dangerous defect at some point—enough to warrant a pre-purchase inspection. These machines are running relatively light at just over 19,000 miles median (suggesting many are weekend riders rather than commuters), yet they still rack up 1.71 failures and 7.2 advisories per test on average, indicating wear-related issues creep in despite modest usage.

The high advisory count suggests ageing electrics, cables, and consumables are the real maintenance story here rather than catastrophic failures. Before buying, get a pre-purchase inspection and specifically ask about brake condition, wiring integrity, and whether the bike has been stored properly—these older middleweights reward conscientious owners but punish neglect.

We have limited data for the 1999 Kawasaki Gpz500s — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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 211 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 36.9%
Rear Tyre worn close to the legal limit · Front Tyre worn close to the legal limit · Rear Tyre tread depth is below minimum requirements of 1.0mm
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Exhaust & emissions 28.8%
Exhaust is leaking but is not excessively noisey · Exhaust is leaking and excessively noisey
Lighting 25.8%
Drive chain slightly loose
Usually cheap to fix. Worth confirming all lights work before collecting.
Brake wear 25.2%
Rear Brake pad(s) close to minimum limit · Front Brake pad(s) close to minimum limit · Rear Roller brake test indicates slight fluctuation of brake effort · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Other issues 19.6%
Drive chain worn but not considered excessive · Drive chain sprocket carrier worn but not considered excessive
Suspension & steering 14.3%
Steering movement slightly 'notchy' · Rear suspension bush has slight free play
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
