ThunderMax Testimonial Received 6/13/2012
"I finally bought a new Throttle-by-Wire ThunderMax® and, within two Auto Maps, my bike at 900 pounds will pull the front wheel off the ground with no hesitation. All I can say is, if you never had a ThunderMax®, GO GET ONE and don't look back unless you want to see all your buddies faces as you blow by them. I couldn't be happier."
