Kawasaki H2R (High-Class Racing Touring Bike) is one of the most sought-after motorcycle models in the Japanese Superbike racing circuit. With its advanced twin-cylinder engine and four powerful bikes (two of which are street legal) built on Superbike design criteria, the H2R is a highly advanced model for riders seeking high-class performance. With a claimed maximum capacity of 128 kilos (dry), the bike's dry weight is one of the lightest on the market. The Kawasaki H2R is also a “smarter” class bike in the Ninja series, being powered by a variable-frequency, single-piece crankshaft that has variable timing control through a hydraulic clutch. The result is increased corner speed, smooth riding and powerful acceleration.
In reality, the H2R is more of a superbike with an superbike engine. Kawasaki claims that the H2R's dry weight is higher than the street-going version of the Ninja. This is achieved in part by using a two-stage wet fly casting process, a key development for Kawasaki. Wet casting means the H2R's airbox has a larger airfoil and greater clearance, which allows for a larger tire. The result is that the bike weights less than the Ninja's high-performance street version.
Kawasaki claims that the H2R offers up to five times the peak power of its Ninja sibling, thanks to variable valve timing and variable valve spacing. However, we do not know what the peak power figures are. The real test is to find out what the RPMs are, and how fast the bike can go. It has been said that the H2R is capable of achieving up to six horsepower per liter, which is about double the Yamaha's 2021 peak power of 5 horsepower per liter. If true, this would make the H2R the fastest two-stroke motorcycle in history.
Tested at the Japanese Harley Davidson Club track, the H2R claimed a surprising victory over the Ninja, despite having only a third of the total horse power. The Kawasaki H2R performed best out of all the models tested, but fell just short of the record set by the Yamaha. The reason for this is that the testers, who had no access to the dyno data, had to average about seven percent lower speeds than the official record set by the club. With this in mind, we can say that the record might have been beaten a little bit more by the Kawasaki.
Testing of the Honda Civic allowed the Kawasaki H2R to compare its performance with that of the Ninja, which was found to be faster at low revs and faster at higher revs. Of course, the Civic was found to have less top speed than the Ninja. In contrast, the Kawasaki h2r offered a smooth transition from cruising to high speed, but seemed to lack any noticeable gains when going from highway driving to city driving. This seems to indicate that while the engine is capable of providing good power, it may lack the ability to provide reliable performance on the highways.
The performance of the Kawasaki H2R is assisted by its two main components: the inverted fork and the foot-operated clutch-based automatic transmission. The gear shift on the H2R is gear-active; this is assisted by a foot-operated button that allows the rider to shift gears using their foot instead of engaging a clutch. This feature, coupled with the ability of the rider to shift gears using their foot, makes riding the bike much simpler and allows them to focus on other components of the bike, such as the fairing. The fairing, or'seat,' is the part of the bike that protects riders from debris and other parts of the road during off-road rides. The fairing also helps reduce pressure on the body and the control system at the back of the bike, which improves handling and stability.
In contrast, the Ninja's gearbox is mated to the engine. The motorcycle is fitted with seven gears including a forward-only reverse gear. It has been noted by critics that while riding the motorcycle, the rider does not need to engage or disengage the foot levers, which makes the motorcycle easier to control when negotiating tight maneuvers. The only real disadvantage of the Ninja's gearbox is that it lacks an automatic shift. Instead, riders must be manually shifting gears, which can prove to be inconvenient during long distance rides and during race conditions where speed and precision are paramount. Kawasaki claims that future models of their H2R model will incorporate an automatic gearbox.
For riders who are seeking greater maneuverability, the Kawasaki H2R offers great news: the motorcycle comes with a number of aftermarket solutions. A popular item is a rear wheel strut brace, which is designed to improve steering response and handling. Other aftermarket additions include a hydraulic clutch pump, front and rear leaf Springs, and a strengthened chassis. Regardless of what features you choose for your bike, the Kawasaki H2R will give you and your passengers a real sense of speed and adventure as you cruise along the open road.
