I don't know where all they offer them, but the Yamaha group offers a riding school. They offer several actually, throughout the US.
Id give google a try and see what all is available where you live and by whom? Again, Big names like Yamaha, BMW, etc are probably going to be much better schools then Zoomie Zoom's Speed World of Racing. Don't always believe the feedback you get on google / etc about companies, as leaving fake reviews is about as old as the internet itself, but look for consistency, and if there is a problem, how it is handled. Be wary of a company that has tons of reviews and NONE of them negative. People cry, often, there is always someone who will find something to boo hoo about, the chances of a company NEVER making anyone upset about anything EVER are very low. If I see that, it immediately gives me alarm bells that someone is harvesting reviews. Again, how was the negative instance handled speaks TONS about the company. Even if the complaint is petty, just having it there / leaving it there, add's a lot to the perceived legitimacy of the comments.
Also look at the companies policy on refunds. Stuff happens, can you get your money back if something goes wrong? This is VERY important if you are plunking down a few grand for a course!
Finally, and this sounds wrong but here goes. If this is your first experience on a track etc, if they offer rentals of bikes, Id seriously look into it. NOBODY wants an accident, but if one is going to happen, wreck their bike, pay the 50 dollar insurance deductible and be done with it, why wreck yours? Even a slight brushup could cost you thousands in repairs, these things are not cheap! Get comfortable with the whole track thing, learn it, get a bit of confidence up THEN bring your machine to fine tune your skills.
When you take driver's ed classes, they provide the car, so why not let them provide the bike for the same thing essentially?
You know on that. Lets say you took your bike onto a track to run it. If you did tear it up, would your insurance cover that? Im thinking not, and in fact they'd probably drop you like a bad habit on your policy as well because you used the bike for that!
Do they offer racing insurance? If so how bad is it? is it worth it?
