Compare the quotes you actually got.
Start with a quick two-bike check. If you need to understand what changed the price, continue into the controlled experiment.
Already have two quotes?
Enter like-for-like annual premiums. Add total theft excess to compare what could leave your pocket if a covered theft happens.
No quotes yet—or want to test mileage, security or excess? The advanced lab below creates a controlled plan. You still submit each insurer form yourself.

Best for a real shortlist of two or three bikes. Hold your truthful rider facts still, change one genuine policy choice at a time, and record only usable cover.
Set one baseline
This configuration is copied to every motorcycle so the first comparison stays fair.
Add the real shortlist
Registration is optional and remains only in this browser.
Generate one identical baseline run for every motorcycle.
Run the controlled plan
Submit each scenario yourself, then capture up to three usable quotes.
Read the signal
Premium and theft excess stay separate. A cheap headline can still leave more cash exposed.
Paired runs can reveal the local price penalty for a motorcycle, use class, mileage choice, security device or excess within your profile.
Underwriter appetite, live portfolio limits and claims models can move without anything about you changing.
Use the same truthful details for each run so the differences remain meaningful.
