No, you shouldn't cancel your motorcycle insurance in the winter–even if you don't plan to ride. Canceling your insurance means you won't be protected against risks like theft, fire, and other potential damage that can occur while the bike is stored. Additionally, canceling your insurance might lead to higher premiums when you reinstate it due to the lapse in coverage. However, some insurance companies offer "lay-up" policies or seasonal adjustments, which reduce coverage during the off-season to lower premiums while maintaining some form of coverage.
