There are "guidelines". Technically any lapse in coverage will set you back. If sticking with the same insurance company, they may take your circumstances into consideration. They don't have to. But they could.
If you switch to another company and there is a lapse in coverage, they will likely start you at square one. But that also depends on your broker and selling capability and also the insurance company's desire to earn your business.
It's sometimes best to keep fire and theft coverage until you purchase something new. Even if you don't own the bike any more.
A broker or agent knows the current climate best since it's more of an underwriting question than a policy per say.
