I've had very positive claims experiences with Allstate also, both moto and car. But, several years after my last claim (long enough that I was confident that wasn't the reason, it was just the customer churn that insurance companies like to do), they jacked my premiums up so high I really had no choice but to switch. I could've bought a new bike (motorized or non) just with what I've saved in premiums. Progressive has a good reputation, but I was and still am nervous about switching to a company that I don't have any claims experience with.

Anyway it sucks it had to happen, but enjoy the bike shopping.
