After a not-so-unexpected beat-down aboard Dan 2’s Z H2 in bone stock trim, by Mike on his 200hp, 100% Brock’ed out 2016 ZX-10R (w/ Penta Carbon Full Exhaust, Sprint Filter P08 F1-85, PCV with Brock’s mapping, Brock’s-Guhl ECU Flash, and Brock’s Front End Lowering Kit — regeared for roll-ons and sporting beautiful BST Rapid Tek Carbon Fiber wheels with World Wide Bearings Ceramic bearings,) Brock requests a rematch on the derestricted and now-stout (227 RWHP) Z H2 in lush, green ‘Mexico’.
Watch as Brock explains the new mods to the Z H2, including the amazing derestriction flash (no fuel tune) from BT Moto AKA Bren Tuning Moto, which was responsible for most of the amazing gains in the higher rev range. Note that Brock was worried about using all of that new-found power in the real world, so he tried to prepare the best he could, given the fact that the owner is a street rider that’s not really interested in turning the Z H2 into any type of race bike (roll-on or drag,) but is primarily interested in learning to ride his newfound powerhouse in stock/bolt-on form.

In Part 6.2 of the 2020 Kawasaki ZH2 Project Bike Series, Brock demonstrated the individual power gains produced from adding various high-performance aftermarket components to the once tame Z H2 now sporting the Bren Tuning Moto ECU derestriction flash.
In Part 6.3, using the Brock’s Performance Dynojet Model 250I rear-wheel dyno with eddy current brake, used in conjunction with the C3 Tuning Software with Tuning Link, Brock explains the process of fine-tuning the fueling by allowing the dyno to communicate directly with the Power Commander PCV to precisely match all of these components together. This advanced tuning technique not only to produces more average and peak power across the board, but also increases drivability and smoothness as well as quickening acceleration across all RPMs and throttle openings. As always, Brock does his best to break down this rather technical episode into bits that beginners and experts alike can ingest and enjoy.

Continuing from Part 6 of the 2020 Kawasaki ZH2 Project Bike Series, Part 6.2 demonstrates the power gains from the addition of performance-enhancing mods such as installing a Sprint Filter P08 F1-85 high flow polyester air cleaner and a Brock’s Performance Penta-Carbon Full Exhaust System. A Dynojet PCV was also added to adjust the fueling in conjunction with the Bren Tuning Derestriction Flash and Brock goes into detail on proper installation and tuning of this powerful combination on the Brock’s Performance Dynojet Model 250I rear wheel dyno, with eddy current brake, used in conjunction with the C3 Tuning Software with Tuning Link.

The video that took 527 days to create IS HERE!
In Part 6 of the 2020 Kawasaki ZH2 Project Bike Series, Brock takes you along, recorded live, as he and his team finally test the 2020 Z H2 in derestricted form thanks to the work of Brendan Griffin and his team at Bren Tuning Moto. Because the original Z H2 project bike, delivered in March of 2020 by Dan (aka: oldkawboy) is living a comfortable life in the twisties of Tennessee, Brock borrows a local 100% stock Z H2 to handle the task at hand – owned by naturally, another Dan (no confusion here).
In an attempt to demonstrate proper before/after performance results Brock heads out for a spirited ride in neighboring “Mexico” with fellow enthusiast Mike on his 2016 “Brock’ed Out” ZX-10R to gauge side-by-side performance before heading back to the dyno to test various power-freeing combinations on the dyno.

“Happy Birthday To You….”
Brock says goodbye to Dan Millholland’s Z H2 that he dropped off mid-March 2020 and now owns the distinction of being the longest delayed project in Brock’s Performance history.
Instead of harping on the “c-word” Brock explains what was able to be accomplished, during this crazy time in American history, and details the end results. During the process of installing a Brock’s Performance clutch conversion into the Z H2, Brock takes the time to explain the operation of this new and ‘growing more popular with the OEM’s’ clutch configuration and looks back at some of the history that led to the slipper/assist clutch development over the years.
Complete with Z H2 configuration and dyno charts, this video has something for most enthusiasts.

2020 Kawasaki Z H2 Supercharged Streetfighter Product Development Update: Bolt-on Swingarm Extensions Installations Video with Additional Considerations Discussion.
Bolt-on swingarm extensions are a quick/easy/economical what to safely increase the wheelbase of most motorcycles so as to increase high-speed stability and decrease wheelies for quicker E.T.s at the drag strip – BONUS… stretched bikes look MUCH COOLER!
Now, before we hear from the “OMG…why-Why-WHY would you ruin the look and handling of such a fantastic machine?!” Gallery, please remember this video is not intended for you. We will address riding a 220+ RWHP sportbike with a 57” wheelbase soon enough.
For those interested in the benefits of a longer wheelbase, regardless of which make/model you ride, please watch on as Brock not only discusses the proper installation techniques in regard to bolt-on extensions, but he also outlines additional considerations to address while doing so. Having all of your “ducks in a row,” as they say can help alleviate frustration as well as additional downtime.

Where do new motorcycle products come from? Most enthusiasts go online or to their local dealer, make their purchase, and call it done. Using his friend Dan’s brand new Kawasaki Z H2 2020 Supercharged Streetfighter, Brock demonstrates why it’s a bit more challenging to create #stupidfast parts promptly than it is to drive up to a speaker and request a ‘Big Mac, hold the pickles.’
Brock gives a glimpse into the development techniques that designers, engineers, and manufacturers use behind the scenes to create cool parts for your ride… while also answering the inevitable questions that pop up before, during, and after you make your purchase decision such as…
‘What are the advantages of adding a slip-on exhaust to an otherwise stock machine? Are there any disadvantages? What happens to the air-fuel ratio when a high flow Penta-Carbon slip-on is installed, especially when combined with the addition of an ultra high-flow air cleaner like the groundbreaking Sprint Filter P08 F1-85? With no means currently available to tune the air-fuel ratio to match these components to the bike…are we risking engine damage by installing these parts? The bikes dash lights up like a Christmas tree, blocks the ability to adjust some parameters, and disables the quick shifter after a few moments on the dyno – Is that a ‘limp mode’? Is the bike hurt? Can we remove the lights/clear the codes on our own, or do we need to slowly make our way to the nearest dealership?’
Find out the answers to these questions and MANY more in the epically long and detailed: Kawasaki Z H2 Supercharged Streetfighter Product Development
“240 HP Ninja H2 SX with a slip-on…what will it make with a full system on race gas?!”
You asked, Brock delivers. After installing the new Brock’s Performance Penta-Carbon™ Full Stainless Exhaust and working some ECU Flash magic with Don Guhl, our friend Charles’ H2 SX cranks out an astounding 260 RWHP on VP MRX02 race fuel.
As an added bonus Brock compares the specifications and power potential of the 2018 H2 SX with the new 2020 Z H2 supercharged street fighter and his personal 2015 Ninja H2, since they were all just chilling out together – a comfortable 6 feet apart.

A streetfighter is a sportbike that is customized by removing the fairing and making other changes that result in an overall more aggressive look.
A hyper naked streetfighter combines the definition above with even more aggressive styling with a more powerful engine and brakes.
A #stupidfast hyper naked streetfighter combines both of the above definitions… along with Brock’s ability to take an already strong supercharged platform and extract mind-bending performance from it.
The Japanese claim that streetfighters emerge from the “darker/unconventional side of a vibrant non-conformist sub-culture”. We are pretty sure they haven’t seen Brock’s idea of darker, unconventional and especially, non-conformist just yet! Our Z H2 streetfighter will ingest enough #stupidfast steroids to gain the respect of even the toughest most powerful in the game.
Updated (11/12/21): Kawasaki Z H2 (2020) Dragstrip Performance
Dan and Chad Millholland are back at the Beech Bend Raceway Park with the ‘Stock-2-Brock’ Z H2! After being rained out on their last attempt to show real performance numbers, they were ready to put the rubber on the track and the numbers on the board!
Equipped with a Penta-Carbon exhaust, Sprint Filter P08 F1-85 air filter, BST Rapid TEK carbon fiber wheels, a Bren Tuning Moto Stage 2 ECU flash with Brock’s Stage 2 PCV mapping, and Brock’s Performance swingarm extensions, it didn’t take long for the Millholland’s to drop their previous best of 9.257 down to a 9.02 in the quarter-mile!
As you can see from the image of the little Z H2 wheelieing-away from a nitrous GSX-R1000, some additional gearing and chassis adjustments still need to be made to keep the bike moving forward instead of UP!
Eight-second passes are on the horizon, stay tuned!
Update (10/26/21): Dan Millholland and his son Chad take their ‘Stock-2-Brock’ Z H2 to the dragstrip (Beech Bend Raceway Park) for a performance update.
Already equipped with a Penta-Carbon exhaust, Sprint Filter P08 F1-85 air filter, and BST Rapid TEK carbon fiber wheels; the Millholland’s take the next step in performance with a derestricted Bren Tuning Moto ECU and Brock’s Performance Swingarm Extensions.
The pair planned for a day of stellar testing before mother nature came in and dashed their hopes. But before the rain fell, they were able to squeeze in an off-the-trailer pass with an improved 9.257 ET from their previous best of 9.614.
First Pass: Dan Millholland and his son Chad take their Brock’s Performance equipped Z H2 to their local dragstrip (Bristol Dragway) to see what it’s made of.
