The 2004 Aprilia SR50 falls short of the UK average with a 75% first-time pass rate compared to the national 80%, suggesting these scooters face slightly more reliable headwinds than typical—though the 13.6% rate of dangerous defects isn't alarming, it's worth noting as a buyer concern. These machines are running relatively low mileage at an average of 15,475 miles, which is modest for their age and suggests many have been garage-kept or used sporadically.

The average of 1.33 failures and 3.0 advisories per vehicle indicates routine wear items and minor issues rather than systematic problems, pointing to normal maintenance rather than hidden structural weaknesses. Before purchase, get a full pre-sale inspection focusing on the ignition and fuel system—the bread-and-butter failure points on aging two-strokes—since you're buying into a scooter that's already slightly below average on first-pass reliability.

The 2004 Aprilia Sr50 passes its MOT first time at roughly the UK average rate (75%) — 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
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 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 530 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 530 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 35.7%
Rear Tyre worn close to the legal limit · Rear Tyre tread not clearly visible
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Lighting 22.8%
Rear reflector on motorcycle missing · Headlamp aim too high · Rear position lamp does not illuminate immediately when it is switched on
Usually cheap to fix. Worth confirming all lights work before collecting.
Brake wear 19.3%
Front Brake pad(s) close to minimum limit · Rear Brake pad(s) close to minimum limit · Front Brake pad(s) less than 1.5 mm thick · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 16.3%
Steering headbearing has excessive free play · Steering headbearing has slight free play · Nearside Front shock absorber has light misting of stanchion · …
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Exhaust & emissions 9.6%
Exhaust noisy
