The California Superbike School was great! I did level one and can honestly say I am a better rider as a result. Training is based on the physics and mechanics of why a Motorcycle handles the way it does. Classroom session followed by track, each session builds on the previous with a coach review after each session. Their rental bikes are newish BMW RRs. 403 lbs, 200 HP! I was late to register and the rentals were all spoken for so I rode my 650V.
My objective was not speed but simply to become a better rider with more confidence. While I would have loved to ride the BMW, I am glad I rode my V. She handled beautifully and the chicken strips on the rear tire are all but gone. I now have more confidence in myself and the V.
I highly recommend this training, go as fast as you are comfortable to go on a race track, 50 foot wide track no oncoming traffic. Parking lot training classes are great for what they teach, but this training is totally different. You can read books and watch videos but actually practicing at speed on a track makes all the difference.
