Kawasaki's H2 Superbike

Help Support Ducati Forum:

Now that I've seen the teaser pics, I think the H2 will weigh at least 30 pounds more than the H2R....


Street H2


H2R vs. H2
 
Interesting if true. This would translate to $80k and $40k USD respectively.

"According to sources at Kawasaki, only 10 'R' models and 15 street-legal H2s will reach UK shores at a cost of £50,000 and £25,000 respectively. Both will be available in March next year." Viserdown Link

Visordown recently speculated on the prices of the Ducati Scrambler upper models in the USA and then later reported the actual UK prices, saying UK taxes are a big factor. The Full Throttle, Enduro and Classic are $9,995 here and £7,995 there. That equates to a .80 multiplier difference and working backwards from the £50,000 and £25,000 prices equates to $62,500 and $31,250, respectively - the former US number being the same as what was purported to be a manufacturer's invoice for an H2R posted a few pages back in this thread.
 
Here's an interesting thought I calculated just for grins. Let's assume that the H2R will put about 270 hp to the rear wheel (10% drivetrain loss from 300 hp at the crank - a bit less than usual for motorcycles). Let's also say that the H2R's SSSA, supercharger and associated plumbing makes the bike weigh about 20 pounds more than a street-legal ZX-10R, despite the carbon fiber bodywork and no lights, at about 460 pounds. Put on a 165 pound rider with 15 pounds of helmet and safety gear, and compare the following chart of Power-to-Weight ratios (with minimum weights provided by each racing series and rwhp estimated from reliable sources):







If these assumptions are anywhere close to reality, then the H2R is actually going to accelerate faster than Tom Syke's Championship Winning ZX-10R WSBK, but nothing on 2 wheels that can make a U-turn on the road is going to come close to a MotoGP Prototype (thank goodness!).



The last column makes some predictions about the street H2. With lights/signals and non-exotic bodywork, it should weigh at least another 20 pounds more. With a 10% drivetrain loss of the estimated 250 crank hp to the back wheel, it still will provide an other-worldly level of acceleration compared to the current paradigm of sport motorcycles. I think I might be interested after all...


And that 20 lb difference will drop once that huge exhaust is gone!!

Good information regarding Viserdown's speculation on the scrambler, and the corresponding $62,500 to the leaked (though still suspect) invoice seems to be either a confirmation of the invoice or a cleverly orchestrated attempt to appear so. If that is indeed the dealer price, I'm curious how much more the M.S.R.P. will tack on.

A few notes on the numbers...the SBK and MotoGP weights should be higher, the minimum weights you have are wet without fuel i.e. how the bikes arrive at the end of a race. Also SBK rwhp is a bit lower. Both of these adjustments mean that the H2 will be even more impressive, if it arrives with these specs!

You left one out (mine lol):

1987 Carrera Cab 2612
Rider/driver 180
Total weight 2792
Wheel HP 485
ib/HP 5.75
 

The street trims displayed in these pictures look better than what I was expecting. This bhp figure, however, will be quite disappointing if true - especially if the H2 is to be priced at ~$30k.

Two things I would say here....A bike costing 20k in the Uk does not automatically translate to $30K here..(Case in point 1199s in Uk is over 20k Pounds).. Secondly the figure they quote is Bhp not Hp..therefore you should probably add 20hpish to that number for a true comparison....So..If the bike is circa $22k and has 220Hp..I am very interested....:)

Not quite enough for your needs ?

You may be confusing bhp (brake horsepower) with rwhp. BHP is essentially measured at the flywheel, and although it is a more accurate measure of horsepower than theoretical horsepower in that it accounts for frictional losses within the engine, it does not account for the substantial frictional losses within the transmission or those losses which occur during transfer of power from the output shaft to the ground.

If the H2's bhp truly is 200, then its rwhp will likely be closer to 180-185, which doesn't place it comfortably above the competition from my perspective; particularly when considering the likely added weight as well as the possible lack of maneuverability when compared to other similarly powered, and possibly similarly priced, NA liter bikes.

Good point regarding the price correlation - I'll try to remain optimistic that the US price won't reflect current exchange rates, although if these power numbers are accurate, I'm not sure it would be worth $22-25k.
 
I saw a pic today of the race version in carbon inside an issue of Australian Motorcycle News and it looked nice.

I normally do not like black or white on a bike but the H2 looked spectacular.
 
That doesn't sound stock?? :D

Ha, not hardly. 217 was stock when I bought it new (930 was 282). Back in '94 I bored it to 3.4, turbocharged it, added Electromotive, twin plugs, etc. It was a turbo-look, so same body/suspension, just no turbo :)

Nice! Post pics! Love the older 911!
