I want to learn to do stoppies, wheelies on my Kawasaki 636..?

Im sure my 2005 Kawasaki 636 is not a goo starter for learning freestyle stunning on .. What motorcycle would be almost perfect to practice freestyle motorcycle stunts on? I only have 1 chance in life of living and I want to make best of it by doing what I want to do ... So please keep the negative comments to yourself and help me with this ... Thanks on advance
