Protect this bike
Insurers often ask for security rated by Sold Secure or Thatcham. These are the layers that make a bike slower and noisier to take.
Ground anchor and chain
Locks the bike to something that can't be lifted into a van.
Alarmed disc lock
Stops it being rolled away and makes noise if someone tries.
GPS tracker
Helps police find it if it does go. Some insurers ask for one.
Cover
Thieves pick bikes by sight. A cover hides the model.
How this score works
We take Harriers recorded stolen in national records and divide by the average number licensed, then rank that rate against 932 motorcycle families with enough data. The likely range is 66–97.
It compares models. It isn't the chance that your bike will be stolen, which depends on where and how you keep it.
Recent reports
Stolen-bike reports from riders and forums. They show what's happening now, but they're a sample, not the official count, and they don't change the score.
Compared with similar bikesNot enough datatoo few reports to compare
We don't show this comparison until there are enough reports for similar bikes.
How we count theseReports by month
Not enough dated data yet.
Months with no reports show as zero. This month isn't finished, so it's left out.
Where they were reported
Not enough reports to show areas yet.
Reading these figures
The official national record, the number on the road and recent reports are three separate sources. Some comparisons are hidden when there isn't enough data. The national record can count the same bike more than once, and recent reports aren't a national total. The method page explains more.
