After a day of listening to blown harleys and NoS busa, the KX5 sounds especially sweet!
Let me know if you have any questions!

p.s. Really read and re-read the section of the rulebook regarding rider safety equipment. Specifically items like dampers, solid panel leathers, SNELL helmets. The bike prep is pretty easy and there are so many classes to run that the bike will sure to fit somewhere.
also... Just thought of one more thing to consider....pretty sure that you need to run tires that are rated equal to the record speed for the class you entered in, not the speed of your bike. Maybe run TO only?
