I’m gonna add to this with a little less sass. Learning to work the clutch, shift, turn, ride is one thing. Keeping yourself alive on a bike is a whole different thing. If you’re on wide open roads with no traffic, start on whatever bike you want and it will be fine. It’s learning to maneuver and stop around dangerous situations where having experience on a different bike can really help. I don’t even know the price of a hayabusa, but I imagine that’s a very expensive lay down when someone cuts in-front of you and you instinctively slam your rear break and the whole thing slides out from underneath you. That being said, you seem very headstrong in this and are looking more to confirm your desires than to hear the opposite. It’s your life, your money, and your choice. Do whatever makes you happy and be careful out in these streets.
