Ya thats what i would of guessed for a stock bike Low to Mid 40's. If you put a Bigger Carb, Pipe, Impeller, and intake grate talk about a whole different machine. That's what has been done to mine and I'm going to bring the GPS out with me this summer. It has already been up to 80'F last week but its cold and raining again and the lake is still only 57'F so the only ski i have been getting out is my GTX.i might be pulling this out of my butt but i seem to remember reading a Kawi factory manual for one of those and 41mph stands out in my mind.
anybody out there to back me up/prove me wrong?
