Moderate sample. 464 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1997 Honda ST1100 passes its MOT at 81.3%, marginally above the UK average of 80%, which is a solid result for a 27-year-old motorcycle. However, nearly a quarter of these bikes (23.3%) have recorded a dangerous defect at some point, which is notably high and worth investigating during a pre-purchase inspection.

These ST1100s are running at a modest 45,348 miles median—reasonable for their age—but they're averaging 1.73 failures per test and 6.8 advisories, suggesting wear is catching up with age. Before you buy one, get a full mechanical inspection focusing on the areas flagged most often: check the service history carefully and budget for addressing any advisories that have accumulated, as ignoring them tends to compound into MOT failures on the next test.

The 1997 Honda St1100 passes its MOT first time at roughly the UK average rate (86.3%) — solid but worth checking this vehicle's history carefully.

⚠️ 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.

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.
🔧 Expect consumable spend. An average of 6.8 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 464 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.

What tends to go wrong

Across 464 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 73.4%
Front Tyre worn close to the legal limit · Rear Tyre worn close to the legal limit · Front 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.
Brake wear 50.9%
Rear Brake pad(s) close to minimum limit · Rear Brake disc(s) slightly worn · Front Brake pad(s) close to minimum limit · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 30.7%
Steering movement slightly 'notchy'
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Exhaust & emissions 20%
Exhaust is leaking but is not excessively noisey
Lighting 13.9%
Exhaust slightly deteriorated
Usually cheap to fix. Worth confirming all lights work before collecting.
