How many WK Bikes SX motorcycles are left?

At the end of 2026 Q1, DfT recorded 168 licensed and 155 SORN vehicles in the UK within the WK Bikes SX generic-model group.

Is the SX disappearing?

Licensed numbers peaked at 383 in 2023 Q1 and stand at 168 in 2026 Q1, down 56%. That is up 380% in the five years since 2021 Q1. A further 155 are declared SORN — 1 in 2 of the 323 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 and when it shows up in the statistics

DfT codes every vehicle in the WK Bikes SX generic-model group as petrol.

WK Bikes SX first appears in the published DfT series in 2020 Q4. Earlier quarters in this file do not include it, so that quarter is not a production start date.

Before you buy

• Ask why it was off the road — Of the 323 SX vehicles still on the DVLA record, 1 in 2 is SORN (155 at 2026 Q1). A car that has been laid up needs a closer look at brakes, tyres and the MOT history.
• Budget for a shrinking fleet — Licensed numbers are down 56% from the 2023 Q1 peak of 383. Fewer cars on the road usually means fewer donor parts and fewer specialists.
• Check the actual SX — These figures describe the model group. Enter the registration for that vehicle's free MOT, tax and mileage record before you pay a deposit.
