The 2004 Suzuki GSX1400 is more reliable than average, with an 89.5% first-time MOT pass rate well ahead of the UK's 80%, and only 15.1% of examples have ever recorded a dangerous defect—a manageable concern for a 20-year-old sports bike. The 1.65 average failures per vehicle suggests occasional issues, but the 6.3 advisories per test reveal that wear and tear accumulates steadily, particularly on ageing components.

At 14,726 miles median, these bikes have been genuinely well looked after for their age, which directly explains the strong pass rate; this isn't a high-mileage workhorse, it's a cherished enthusiast machine. Before buying, ask for full service history and have any bike with multiple advisory items inspected by a specialist—the pattern indicates electrical, rubber, and brake components need close attention on older examples.

The 2004 Suzuki Gsx1400 passes its MOT first time at roughly the UK average rate (89.5%) — solid but worth checking this vehicle's history carefully.

⚠️ 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.

For context
Good baseline reliability. A 89.5% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 6.3 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 636 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.

Exhaust & emissions 81.8%
Exhaust noisy
Tyre wear 65.1%
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 · …

Brake wear 38.4%
Front Roller brake test indicates slight fluctuation of brake effort · Rear Brake pad(s) close to minimum limit · Front Brake indicates slight fluctuation of brake effort · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
