Do I need motorcycle to take MSF course

No, they will provide you with one. But if you already have one then you may use it too but for that your motorcycle needs to be preapproved. They will also have spare helmets but you may want to contact them directly for details.

If you are taking the beginners class they have bikes available. If you have your own 350cc or less i believe they will let you ride yours if it passes inspection. The more advanced classes require you to bring your own bike and pass inspection. They do require you to wear long pants, boots that cover the ankle, long sleeves, and gloves. They have helmets but if you have your own bring yours. I cannot remember if they require a full face or not. If you already have your own safety gear bring it. If that is what your going to ride in you want to know how it's going to feel for you on the bike.
