I'm selling my banshee. It has a 4 cylinder 1000cc 4 stroke Yamaha R1 engine in it. The engine has a Nitrous Oxide system installed on it. It's set up to shoot in automatically when you have the throttle floored. The bike also has an air shifter to make all of your shifts in a mili second. I used this bike for ATV drag racing and was sponsored by Yamaha. I have way too much money put into this thing, but it is scary fast. I usually don't even us the NOS. I think I've used it a total of 3 times. I've seen times of Under 4 seconds in 300 feet using this bike. No 4 stroke ATV can match it at all. It has dominated that class recently without nitrous. I've put well over 15k in it easily, but I've lost count after that. I'm asking 10k for it, but will consider trades. E-mail me for pics.
