Brock dyno tests the new Z H2!!

Post by Steve Smith » Thu Mar 19, 2020 5:46 pm


This new video came out a day or two ago on YouTube. A friend of his delivered his own personal Z H2 to Brock for use as a "test mule" in developing an ECU flash program (from Don Guhl), dyno tests and performance parts.
Stock, it made 184 RWHP and 94 ft lbs of torque! More than the ZX10R and quite a bit more than the H2 SX. This thing is gonna be an awesome street bike/ racer and a monster at the drag strip after Brock has the proper bolt on goodies available.
I should be getting mine in the next couple weeks. :cheer: You can bet a slip-on, reflash , swingarm extenders and a small windshield are already on my short list.

The dyno compared to the H2SX looks like they just didn't restrict the top RPM range as much in the stock programming. I would like to see the final tuned numbers and would expect them to match the SX numbers.

This is exactly right. The Z H2 is just less ECU restricted from the factory at the top. I guess they assume a younger, more wild consumer might by the Z. But it's the same engine as the SX so it should make roughly the same rwhp after tuning. It even has the exact internal gear ratios, and a 46/18 sprocket combo vs a 44/18 on the SX. Nearly identical.

The wheelbase is about 1" shorter and it's lighter, so it will be more flickable and the front wheel will come up a little easier. That's about the only difference other than looks.

I understood that the torque hits it's peak 1000 rpm sooner than the SX versions too. According to Kawasaki's web site, the Z H2 is 50 lbs lighter.

I saw the video as well. It is interesting and for sure there will be a market for this beast, but I still like the SX much better.

50lbs is 50lbs but we also have a fairing so at higher speeds the SX should be more stable and more comfortable to manage.

I'm not in the market for a $25,000 sport tourer. I'm looking for a street bike that'll kick some butt not just on the street, but mostly when I drag race it at my local drag strip.
Basically comparing red apples to green apples. Also, list price vs list price, well, do the math.
Not looking for a top speed bike either. Kaw already offers a decent windshield for the bike to tuck behind when racing , and I'm sure many aftermarket companies will eventually do the same.
