The numbers, and where they come from
Datatool, a UK vehicle security and tracking company that tracks theft data from DVLA records, reported over 16,500 motorcycles registered stolen with the DVLA in the twelve months to mid-2026. London alone has accounted for over 9,000 stolen motorcycles, scooters and mopeds in a single recent year according to the same reporting. Separately, the BBC has reported that almost 90% of motorcycle thefts in England go unsolved, underlining that recovery, not just prevention, deserves real attention alongside locks and alarms.
These figures move year to year and shouldn't be treated as fixed, but the consistent theme across UK theft reporting is worth taking seriously: theft is concentrated, both by location and by time of day, far more than random chance would suggest.
Why overnight hours matter most
Datatool's own theft data points to the overnight window, particularly midnight to around 4am, as the period when a large share of thefts happen, especially for lightweight, easy-to-lift commuter bikes and scooters that can be carried into a van rather than ridden away. This lines up with simple logic: fewer people about, fewer witnesses, and more time for a thief to work on a lock undisturbed.
For riders who park on the street overnight, this is the single window worth the most attention - a bike left in the same spot every night is a known, predictable target in a way one moved or checked periodically isn't.
Location matters as much as time
Theft is heavily concentrated in dense urban areas with high bike ownership and easy escape routes, which is exactly why cities report disproportionately high numbers. Off-street parking, even a driveway or a shared residential compound, meaningfully changes the odds compared to consistent street parking, simply because it removes the easy, low-risk approach a thief relies on.
Commuter bikes and scooters face a different risk profile
Datatool's reporting has specifically flagged lightweight, easy-to-lift commuter machines, popular models like the Yamaha NMAX 125 and Honda PCX-class scooters among them, as disproportionately targeted, since they're light enough for two people to lift straight into a van without needing to defeat the ignition at all. A disc lock alone doesn't stop a bike being carried rather than ridden away, which is exactly why a ground anchor or immovable object matters more for this category of bike than for a heavier machine a thief would struggle to lift.
What this means for security choices
None of this means street parking is unsafe by definition, but it does mean the overnight hours deserve the strongest layer of security you have, since that's when opportunity is highest and witnesses are lowest. A ground anchor or disc lock earns its keep specifically in that window. A recovery layer such as Recovery Tag Pro matters most for the roughly half of bikes that, per Datatool's recovery figures, are never seen again once taken - giving a finder or the police a scannable way to confirm ownership if the bike does resurface.
Understanding the pattern doesn't prevent theft on its own, but it does tell you where your effort and budget are actually best spent, rather than spreading equal attention across every hour and every parking spot.
