A stunt-bike, as you may know, is a motorcycle built to run on one wheel without effort and to get wheelies with a simple throttle turn, independently by the horse power. How can it do that? With the proper transmission, of course!
We re-projected it to have the maximum torque at low rpm with a new 18 teeth-9mm offset pinion to center the new 180mm rear tyre, together with a 65 teeth sprocket and 525 chain.
To complete our work we fitted our dinamic chain tensioner.
Wheels are 17” Kineo (http://www.in-motion.it/main.php) super lightweight elements.
