so then what's your guess for the realistic top speed on an unrestricted 300hp bike?

The 300hp+ version is a halo vehicle that isn't even street legal. Its a trailer queen to bring to dragstrips and maybe to the occasional trackday (So you can watch the 600's and maybe even a couple of 250's lay down better times)

The street version is probably replacing the ZX14 in the lineup resulting in the same performance jump we saw going from the ZX12 to the ZX14.
Considering the ZX-14 is a nice sport tourer with a nice side bonus of being a natural on a drag strip, the H2 street version will probably continue that trend.

Since Suzuki and Kawi love to have top dog status, expect a new Hayabusa next year with a twin turbo 2.0 V12.

huh?

as jules said....bolded...not accurate

there are a number of bikes in the 190hp range these days
None of what you said challenges what he said. The most recent Busa only does 170ish to the rear wheels. So nothing about that statement was wrong or corrected with your last comment.

You don't need 300hp to do 200mph on a bike.

Japanese bike manufacturers have agreed to limit the top speed to @186mph since 2001+ to prevent import bans. The Suzuki Hayabusa only has @155-162hp depending on year, and it can do 185-196mph depending on whether or not it is restricted.

The fastest a MotoGP bike has gone to date is 217.2 set in free practice this year at the Italian GP on a Ducati GP14. They won't reveal true HP numbers, but 235+ is the official rating.

I think the discussion is mixing Crank HP with Wheel HP creating confusion.

Busa makes 160ish at the wheel and weighs around 540lb.

In comparison, the BMW HP4 which is currently the top dog makes about 175hp at the wheel and weighs less than some Busa and Harley riders.

Manufacturers do limit bikes 186.
The last year of non restricted bikes was 99 (I think. Haven't looked it up. Just going by memory)

Gearing matters. And the faster you go the more aero comes into play.

I have a ZX-11D. At most it put out a lowly, antiquated 127 RWHP (145 at the crank).
Its been tested up 175mph.
The fairings really do help once you start getting into the triple digits.

I have a CBR1000rr as well. High 170's at the crank. Mid 150's at the wheel.
Tested top speed is usually high 170's, 180. 30+ hp bought 5 mph at best

On the old, rickity ZX-11 (back when I actually took it out of the garage), I could cruise at 120mph and comfortably run it up to 150mph+ speeds. I've had that thing showing mid 180s indicated (once when I first got the bike on a empty stretch of highway, other times on the runway at the old Grumman place.)

On my CBR, one it hits around 150-160 it just gets messy. Brute forceof the motor fighting it out with aerodynamics to much

Hey guys, I really love bikes since I was a kid and thinking about getting into riding. I just got back from a deployment to Afghanistan and have a big combat paycheck coming to me. Do you think the H2R is a good bike to learn on? I know I know, I'll take it easy at first until I get the hang of things.

140mph is about the top speed of my bike. Not sure I'd want to go any faster than that on a naked bike. I've had it up over 120mph a couple times. That is fast enough for me.

LOL!

Back before I entered the wonderful world of fairings, I rode an 83 CB750 in all its federally mandated 85MPH speedo glory.
The fastest I ever went on that bike was exactly "Peg that was a little past 85MPH"

Yeah but the H2 doesn't seem to me that it will be a natural on the drag strip. Short (looking, I don't know the number) wheelbase means its going to have a lot of trouble even with all the techno wizardry.

Nothing a stretched swing arm wouldn't cure. :ninja:

I want one of these so bad and I am in no way experienced to ride one. I envy bikers.

In 1982 I had a 1979 CB750SS and I was arrested for "speeds in excess of 125 MPH".
I had a jailer waiting to talk to me when I was brought in to find out what I was riding. :biggrin:
