So I assume you now know what a Busa is. For the rest of you, Busa is short for the Hayabusa, I own a Suzuki Hayabusa, the fastest motorcycle ever made and that ever will be made. Well, maybe I can't
guarantee that no motorcycle will ever be made to be faster than a Hayabusa let me explain. In 1999 the Hayabusa was first manufactured by Suzuki. It would exceed 200 MPH but the public said "No motorcycle should ever go that fast. There should be a law". Before such a law was ever enacted Suzuki voluntarily speed limited to 186 mph or 300 kph (yes I know you are all thinking that's much safer than driving 200 mph). My 2004 Hayabusa is one of those speed limited models. The fuel injector cuts out at that speed.
Now all motorcycle and performance car manufactures voluntarily speed limit their vehicles to 186 mph. There are some exceptions. The extreme high end performance cars that cost about a million dollars don't abide by that rule. BTW my Busa has the speed limit and won't go any more than 186 mph (not that I've ever gone that fast anyway)
So I've got a motorcycle that is built to go fast and a jeep that's built to go very slow. When I'm in my CJ5 on the highway up into the mountains I often pull over because I am thinking I am driving too slow for the other traffic. If I am on my Busa then it's the other way around, I never hold up anyone else.
