The 2001 Yamaha YN50 passes its MOT just below the UK average at 78.6%, suggesting reliability that's respectable but not outstanding for a scooter of this age. One in six of these machines (16.2%) has recorded a dangerous defect at some point, which is worth factoring in if you're buying used.

With a median mileage of just under 8,000 km, these scooters typically haven't been thrashed, but the average of 1.48 failures per test hints at wear accumulating in specific areas—most likely suspension, brakes, and lighting on a machine this old. Get a pre-purchase inspection focused on the electrical system and any rust spots, as the 3.1 advisories per vehicle suggest corrosion and minor component fatigue are common.

The 2001 Yamaha Yn50 passes its MOT first time at roughly the UK average rate (78.6%) — 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 3.1 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 643 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 643 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 36.8%
Rear Tyre worn close to the legal limit · Front Tyre worn close to the legal limit · Front Tyre valve stem slightly damaged · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Brake wear 28.8%
Front Brake pad(s) less than 1.5 mm thick · Front Brake pad(s) close to minimum limit · Front Stop lamp does not illuminate immediately a brake applies · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Exhaust & emissions 13.5%
Exhaust is leaking and excessively noisey · Exhaust is leaking but is not excessively noisey
Lighting 13%
Headlamp aim too low · Headlamp aim too high · Exhaust slightly deteriorated
Usually cheap to fix. Worth confirming all lights work before collecting.
