I've been to Freddie's School. His techniques are completely suited for street riding. That's part of the "gist" of the class.
I alternate between trail braking/body steering and countersteering depending on what kind of riding I'm doing. If I'm canyon carving on familiar terrain, I use Freddie's technique. If I'm just loafing around, I am likely countersteering. But, if I get into trouble, without thinking, I change to Freddie's technique. They drill you like the military in his school so that the techniques are second nature. Freddie's technique isn't just about going fast. It's about going fast safely. He'll teach you how to stay up and correct errors in mid-turn (speed too fast for turn, decreasing turn radius, etc), and how to avoid or ride through road hazards that appear suddenly, such as water, gravel, etc, without going down. He's already saved my bacon on quite a few occasions. His techniques also help you get the most out of any given lean angle, and the busas run out of lean angle quick. Hell, his techniques also work on my cruiser (VTX1800C). This is going to sound hokey but, I actually got away from someone on a 600cc sportbike in the canyons recently, on the cruiser! Yes yes I know, had it been a skilled rider on the 600 the VTX wouldn't have had a chance. It is fun to surprise folks that think that they can't be beat on whatever they're riding because of what they heard on the internet or in a sportbike mag. It's not the bike, it's them that needs improvement. That is another of the tenets of Freddie's training. As part of his training you'll be a passenger on the back of his VFR800 whiles he's knee dragging and passing other students in the class who are on 600s (yes, I've ridden bitch with Freddie Spencer...).
If you ever have the time/money to attend his training, you're really missing out if you don't. It's not the same as other track schools.
