Looking at a SX 125?

Population figures cannot tell you whether one particular car is taxed, MOT-valid or safe to buy.

Check its registration free for the official tax, MOT and mileage record. If the car is still worth pursuing, the optional £9.99 full history check adds outstanding-finance, stolen and insurance write-off checks.

Wondering whether one particular SX 125 is off the road? A free SORN check shows whether it is currently SORN, taxed or untaxed.

Is the SX 125 disappearing?

Licensed numbers peaked at 531 in 2025 Q3 and stand at 506 in 2026 Q1, down 5%. That is up 109% in the five years since 2021 Q1. A further 274 are declared SORN — 1 in 3 of the 780 still on the DVLA record is off the road, laid up, part-restored or waiting to be sold.

A falling population is worth knowing before you buy: it usually means fewer donor cars, fewer specialists and slower parts supply, and it is why a good example of a scarce model can hold its price while a neglected one is hard to sell at any price.

Fuel

DfT codes every vehicle in the Aprilia SX 125 generic-model group as petrol.

Before you buy

  • Ask why it was off the road — Of the 780 SX 125 vehicles still on the DVLA record, 1 in 3 is SORN (274 at 2026 Q1). A car that has been laid up needs a closer look at brakes, tyres and the MOT history.
  • Check the actual SX 125 — These figures describe the model group. Enter the registration for that vehicle's free MOT, tax and mileage record before you pay a deposit.
