Motorcycle insurance companies know most of us don't ride our bikes in a snow storm in January so your policy is priced and your premium is earned based the typical riding season. This means how much premium you've earned if you are looking to cancel mid-term is determined by when you started your policy and when you are looking to cancel your policy, not just by how many days it was in force.
Most insurance companies use the table bellow to calculate your earned premium. When it comes time to cancel they will calculate how much premium you have earned by the time of year you have had your policy active and subtract your payments from the total earned premium. If you started your policy at the beginning of September and cancelled at the end of march you would have earned 20% of your total policy premium. If your annual premium was $2400 and you are paying it in 12 equal installments with your first installment in September, and you 7th installment in March you would have paid a total of $1400. Your earned premium would be ~$480, so you would get a refund of ~$920. Most companies will charge a minimum retained premium so if you start a policy in January and cancel in January which has a 0% earned premium you would still be responsible for a small payment to cover the costs of setting up your policy.
If you are looking to cancel be sure to ask your company about their specific motorcycle cancellation policies and how they calculate your earned premium before you cancel, but hopefully the table bellow will give you a better understanding of how motorcycle policies differ from a regular auto policy.
