Been there - my last THREE bikes have all been stolen, one from right outside my front door after a Sunday ride like yours then two from my garage which was VERY organized (they broke into two cars to move them back from the garage door, cut off the padlock from the garage door, drilled and slide hammered out the other lock, cut off the the thick chain threaded through the wheels then drilled and slide hammered out the steering locks.
The insurance company only paid out on one of them on a technicality - even though they took £1000 of me for a rider policy covering any bike I rode they said as one of them wasn't yet registered I couldn't ride it so it wasn't covered.
The cops (well one) did come and told me with a smirk on his face that I should have been more careful about security and "bet you were sorry now".....
Almost a year later my bike (A GSXR !!00R) - well parts of it were scraped up off the road together with another with which it had collided. The rider said he bought it from "a bloke he met at a race meet" who he couldn't remember.
It came to court and he got sent down for handling stolen goods but got off on a conspiracy charge (there were many, many other bikes involved) so if the police find your bike or even identifiable parts of it then they can and do prosecute so sometimes they do their job and for that reason I never get angry when they stop me to check engine/frame numbers etc.
Since then Norwich Union say they won't insure me at my current address (they all but accused me of stealing my own bikes) so despite being £8,000 out of pocket and bikeless for several summers I can't have a bike because I can't get insurance.
To add insult to injury, the thief who crashed my bike and whom I gave evidence against in court appeared on TV - he was a record setting stunt rider Gary Rothwell who gave stunt shows at bike meets including the IoM, bike shows and race meets (no doubt whilst his mates were stealing the bikes of the people watching him). When you think about it, you have to crash an awful lot of bikes to get that good - better if its bikes other people have worked hard and saved for than your own,
When an article about this thieving scumbag twat appeared in Bike magazine I wrote and complained and got an apology from them - it made me so mad that due to him the closest I could get to bikes was reading about them in that magazine and here they were venerating the person responsible for depriving me of my bike!
So - I share your loss - it's the worst feeling looking at the empty space were you bike was....
PS - I regularly get calls from people who withold their number asking about "the bike I have for sale" even though I have no bikes so I guess NU are right not to cover me at this address - bike crime here in the UK is highly organised with 70% never recovered. One bike is stolen every 15 minutes with 25 out of every 1000 taken. Bikes less than 1 yr old are twice as likely to be stolen (mine

) and 50% of bike thefts are perpetrated by opportunists.
