Well, there is such a fan for T1's and T4's, but it's for racing only. They use them in europe, and I have seen them in the states as well. It's a good thought, but you would still have to run a alternator of some sort for street use. This will take about the same horse power to run just like the current fan/alternator set-up that everyone uses. So, the only thing you would gain is a cool factor. There is a picture of one somewhere in the members rides.
