Can i change the vehicle on my insurance policy?

I currently ride a Yamaha ybr125 motorbike and I've been looking at a Honda cbr125r. I want to get the cbr but the insurance on my ybr was paid for the full year. Is there any way I can get the cbr to replace it on the same policy?

Contact your insurer

Yes, it can be done and it is very easy. Simply have the dealer fax your agent the finfo about your new bike, and it will be taken care of You should follow up with phone call, and yoju will be mailed an endorsement in a few days

Of course you may. Simply notify your insurer. They will make the switch for you.

Why wouldn't you ask your insurer this question, instead of asking strangers on the internet?

That's called a vehicle substitution, and insurance companies all do them.
