this dip shit got me thinking.

So i was approached by a guy today who was talking to me about my 51, he was talking about his brothers who "regularly hits 200 mph" i began to educate him but it was impossible. then he began to tell me how the r1 is the fastest production bike out there at 230 mph. so i ended the conversation and walked off.

this got me thinking about the fastest bike out there. so according to sport rider the fastest bone stock motorcycle to date is still the 99 busa at 189.6 after that every other big bike has the gentlemans agreement 186 limiter.

ive been looking at it seems they are right so far. now remember i mean bone stock/showroom stock.

The main limit of speed is wind drag.
Aerodynamic resistance increases with the cube of the speed.
Double the speed, triple the wind resistance.

The less aerodynamic the vehicle, the more power is yet needed.
At 200 MPH or better, it takes a lot of power to push through the air.
The fastest MotoGP bike went around 219, and that took around 250 HP and a narrow bike frontal area.

This is the reason for the shape of the Hayabusa.
It wasn't a styling exercise. It is actually one of the most aerodynamic bikes on the market.
I'm sure it might go a bit faster than 193 MPH ('99 unrestricted model) if it was narrower.
The bike is wide to accommodate the engine, which adds more drag.

I believe this is why the BMW S1000RR reaches or may slightly exceed the '99 Busa's speed, as its engine is a narrower design and has less drag, even though its bodywork is less aerodynamic overall.

yeah from what im looking at most of the literbikes and up will exceed the 186 mark by a decent margin when de-restricted.

I hear story's like that all the time from kids at the Q steak and lube bike nites.
In my area its the gixxer guys that talk all the smack and say those bikes rule on every aspect.
I have looked at their tires and seen the huge chix strips and well that just settles it with me. Kinda funny to just go along with them to seen just how far they stretch it. But once they claim they break the sound barrier than I'm done.

No Novels!

Fricken GOLD battery!

it's kinda funny how the OPs conversation reminds me of my 12yo son's same question everytime he sees a fast-looking car or bike,

"is it faster than your bike?"

"No son, I have yet to find another bike that can rip your arms out of your sockets."

Stunned amazement and silence...

I too find it funny how so many riders talk crap about how good they are and they take these corners at break neck speeds and drag their knee all the time. And all you have to do is look at their back tire for confirmation. The evidence is right there yet they still brag n boast.

While those guys are annoying to me too, you also have to consider not many people drag knees on the street, even if they are capable. Look at my Pilot Road 2 rear for example, I've got obvious strips and a center that is squaring off. That's because I don't try to drag knees or put my bike at that limit on the street. Some guys I ride with do and I've seen too many of them wreck at high speeds or lose their licenses. I can't afford to do either (see my post about my son above).

Then look at my Q2s takeoffs I sold at the end of the last track season. Trust me, they were used right up to the edges. I'm no racer, rather a casual trackday enthusiast who can keep pace in Nesba I group.
