State

With any motor vehicle you'll need your bike or yourself licensed from the Department of Motor Vehicles (DMV) http://www.nysdmv.com

A listing of the DMV's motorcycle information (license, registration, manual, mopeds, etc) can be found here http://www.dmv.org/ny-new-york/motorcycles.php

The DMV has established a rider-funded motorcycle safety program as required by legislation. Taking the safety class exempts you from the road test in getting your motorcycle license, it also gives you a discount on insurance. The motorcycle program also has lots of great information on their web site http://www.dmv.org/how-to-guides/motorcycle-safety.php

The DMV also has a bunch of other motorcycle guides at http://www.dmv.org/how-to-guides/other-vehicles.php
