Just got my 900 cc. But the two day class the state of Texas requires. Once you take the course which is classroom and written testing then next day obstacle course and driving test. Once those two days are done you simply take your certificate to department of motor vehicles, show them your certificate, and they give you a three wheeled endorsement. But all the classes near me are full. Think I am going to have to travel 4 to 5 hours away to do it. Luckily they supply the bikes. ( spyders) for the class. But it will be hotel plus 300 dollars for class, meals, etc.
