Once you get into it, it will be addictive. It is an expensive hobby. Don't hit the track pipe unless you want to keep coming back for more.
If that $200 doesn't include instruction, walk away.
It's a lot more than "just riding around."
Here's a great vid by our own HoPMiX which I love love love.... Stay tuned for the middle section where the guy explains it in very simple terms. He makes it sound like it's just "riding around" - but there's reasons why it's different and better than the open road, and one that he doesn't touch on is instruction.
And... to get a first person view of the action... Watch Stewy tear it up...
But if the expense of the track days themselves make you think twice, consider the fact that you'll need better gear than you're probably wearing now, and depending on the track and organizer, there may be certain changes that need to be made to your bike (usually those would be things like special non-glycol coolant, safety wire on your oil cap and drain, etc... not all require it, but some do).
Again. if the price does not include instruction, find another organizer.
