Dean is correct. I intentionally lowered the front end by not using any extentions. After my accident, I adjusted the rear lower and dropped the fork tube about 1/4 of an inch in the triples to raise the front end. As it sits right now, using an unscientific manual angle gauge on tapered forks. The rake is 25°. Fortunately Casper has the exact same GSX-R1000 forks so I can compare Apples to Apples. I measured the angle on Casper and the rake is 27°. The 25° rake on the Streetfighter is not exceptionally steep. The OEM rake on my VFR800 is 25.5°.
I added the steering stabilizer as a safety measure to make the steering input a constant at max input force.
