Comprehensive coverage pays for damages caused by an event other than a collision, such as fire, theft or vandalism. However, just like collision coverage, your insurance company will pay for damages, minus your deductible, and will cover only the book value of the motorcycle.
Collision coverage pays for damage to your motorcycle if you are involved in an accident. Your insurance company pays for damages, minus your deductible, caused when you collide with another vehicle or object. Collision insurance usually covers the book value of the motorcycle before the loss occurred. (If you finance your motorcycle, you will have to provide proof of collision coverage to your loan company)
Keep in mind that there are limits to the amount of medical payments that your motorcycle insurer will pay, and that this coverage is also subject to a deductible. Most insurance contracts also limit payment for medical expenses to one year after an accident. If you have health insurance, the motorcycle insurance company may seek to apportion payments to the limit of it's liability as compared to all applicable coverage. (Yes, it's complicated)
Additionally, if you are injured because of the fault of another, and you recover money damages from the other driver's insurance policy, you may be required to reimburse your insurer a portion of the money paid for your medical treatment. This is known as subrogation
. Look for a subrogation clause in your policy to determine if you have such an agreement.
Bottom Line: Protect your motorcycle, yourself and your future. Get appropriate coverage, with sufficient limits to protect yourself and your family. Some motorcycle policies allow for lower premiums during the off-season, which saves some money - but you may have to ask for this. However, make sure that you still have comprehensive and collision coverage during the off-season --- just in case --- shit happens
