Sport Rider Cover Story: Ninja H2 Goes 226.9 MPH with Bolt-On Mods
Wednesday, August 10, 2016

 


We take a street-legal Kawasaki Ninja H2, bolt on some Brock’s Performance
Stage II Kit parts, and blast to 226.9 MPH...


After taking Kawasaki’s groundbreaking supercharged Ninja H2R last year and running it against some modified supercars (“Showdown,” Aug./Sept. 2015), I have to admit we’d kind of forgotten about the streetlegal Ninja H2 brother to the racetrack-only H2R. We had the opportunity to ride the H2 around Auto Club Speedway’s road course in California for a press day a few months prior to racing the H2R at the No Fly Zone speed contest, but to tell you the truth, while the H2 certainly had some serious power and was a blast to ride for a day, pulling the trigger on the H2R on that airport runway made the H2 fade into distant memory.


That is, until I noticed that venerated speed merchant Brock Davidson of Brock’s Performance was doing a lot of R&D work on parts for the Ninja H2. Being specifically marketed as a street-legal motorcycle means that Kawasaki has sold far more H2s than H2Rs, and the vast majority of H2 owners have been going to Brock’s Performance looking to unleash the power and speed potential of their “blown” bikes. When I met up with Davidson at the annual AIMExpo in Orlando back in October of last year, he gave me a quick overview of the H2 his company used a month before to set a speed record of 219.40 mph at the Ohio Mile with veteran land speed racer Zack Millholland.


My interest was piqued because an H2 testbike had been previously offered to Sport Rider by Kawasaki. For some time after their debut, Kawasaki USA was keeping a tight rein on the single Ninja H2R and handful of H2 units available and only released them for special circumstances like the “Showdown” story. Those rusty old gears began to turn in my head: Why not build the ultimate "bolt-on" project bike?


Davidson fanned the imagination flames when he informed me his Ninja H2 Stage II Performance Kit boosted power from a stock 208 rear-wheel horsepower to more than 274 hp on the Brock’s Performance dyno (and, no, we have yet to see a Ninja H2R come anywhere near the claimed 310 hp on any dyno…). But it was when Davidson read off the list of parts he used to get that power that I was left slack-jawed and utterly stunned.



The list of parts reads like this: a Brock’s Performance Alien Head 2™ Performance Package including a Brock’s Flash Package (a Guhl Motors re-flashed ECU and Dynojet Power Commander V), and a DNA Air Filter; a Ceramic Front Wheel Bearing Set, Fully Adjustable Window Links™, and a Steering Damper Riser Kit (to allow the fork tubes to be raised without interference issues) are also included. In addition to the performance package we added a Clutch Mod Kit and Rotobox Carbon Fiber Wheels. To think that the simple combination of full exhaust, re-flashed ECU and PCV, plus an air filter could result in a 30-percent boost in power is unheard of in these modern times. Granted, the starting point is a supercharged Ninja H2, a $25K motorcycle; regardless, it’s still an astonishing power increase no matter which way you look at it.


Components like the DNA air filter and ceramic bearings might not seem like they add much to the performance at first glance, but rest assured they make a difference. Brock’s Performance is one of the scant few speed shops that actually tests everything before they agree to sell it. “Oh, I could surely make a lot more money selling all sorts of knickknacks and doodads,” Davidson says matter-of-factly. “That’s not how I work. I won’t sell anything that doesn’t make your bike go faster.”
