The 1999 Aprilia Sonic passes its MOT on the first attempt about 77% of the time, slightly below the UK average of 80%, suggesting middling reliability for a vehicle of this age. The 11.8% dangerous defect rate is manageable, though worth noting when inspecting a used example.

These machines are typically showing around 9,800 miles on the clock at test, which is quite low for a 25-year-old bike—a sign either of careful ownership or limited use. With an average of 1.05 failures and 2.0 advisories per vehicle, expect minor wear items and maintenance issues rather than structural problems; have any candidate checked over by a mechanic familiar with older Aprilias before purchase.

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

⚠️ About 1 in 12 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 102 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Suspension & steering 30.5%
Steering headbearing has excessive free play · Steering headbearing has slight free play · Offside 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.
Tyre wear 22.6%
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.
Brake wear 13.8%
Front Brake pad(s) less than 1.5 mm thick · Front Stop lamp does not illuminate immediately a brake applies · Front Brake disc(s) slightly worn · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Exhaust & emissions 10.5%
Exhaust is leaking and excessively noisey · Exhaust is leaking but is not excessively noisey
Lighting 9.2%
Rear reflector on motorcycle missing · Headlamp aim too high · Exhaust slightly deteriorated
Usually cheap to fix. Worth confirming all lights work before collecting.
