In 2008, Yamaha's street lineup is a tweaked YZF-R6S. The '08 version of the 600cc mount features a modified steering geometry, with rake decrease by a half-degree to 24 degrees even. The change in steering head angle has resulted in a shorter trail figure, with '08 measuring 0.3-inch less at 3.4 inches. The overall length and height of the new R6S have changes as well, with height 0.6-inch shorter (42.9 inches) and length 0.8-inch more petite (79.7 inches). The wheelbase is also exhibits a slight 0.2-inch decrease to 54.3 inches. The other noticeable change on the 2008 R6S is an increase to the front brake rotors from 298mm to 310mm. The $8,299 MSRP remains unchanged.
