For a better response, Why is the company giving you good rates for next year? (turning 25, getting M...)
If you look in the stickies in the insurance section it has SF and TD premium %'s per month. Use that and call an ask if they charge anything for cancellation charges.....
Looking at your last post I dont think you understand motorcycle insurance.....
You dont want to pay insurance all winter.... That goes towards your premium, As stated with TD you use 0% of your premium during the winter and 100% in the rideable months.
So if you started paying now you would have fire and theft over the winter and a chunk of your premium already paid off and a better chance at getting a refund when you do cancel compared to owing hundreds of dollars just to cancel your policy.
