keep note that the factory speedometer reading is about 7% off on a 2003 cbr954rr. Hence if your speedometer says your doing 107mph your really only doing 100mph. This can be fixed... go to www.bluegauges.com, they sell something called a speed correction box($100) that can be adjusted to correct your speedometer... detailed instructions are on the site...or you can just have someone with a radar gun clock you(you can buy one of those from a sports store for about $130) i´ve hit about 183mph on mine but it wasn´t topped out...I plan to soon, but safety is an issue...gotta do it somewhere with no traffic... and at least a mile staight-a-way.
