| Kawasaki H2 look |
This article is about a supercharged 4-cylinder motorcycle announced in 2014. For the 1970s three-cylinder motorcycle, see Kawasaki H2. The Kawasaki Ninja H2 is a supercharged supersport bike in the Ninja sports bike series manufactured by Kawasaki and is equipped with a variable speed centrifugal supercharger.
Its name is the 750cc Kawasaki H2 Mach IV, an in-line triple introduced by Kawasaki in 1972 to "disrupt the sleeper market."
The track-only Ninja H2R is the fastest and most powerful production motorcycle on the market, producing up to 310 hp (230 kW) and 326 hp (243 kW) in Ram Air.
The H2R has 50% more power than the fastest street-legal motorcycle, while the road-legal Ninja H2 has less power with 200 hp (150 kW)[21] - 210 hp (160 kW) ram air. .
design
Rather than continue with the high-displacement Ninja ZX-14 hyperbike, Kawasaki chose a liter bike platform for its top-tier Ninja H2.
Cycle World's Kevin Cameron explained that the liter bike class is "at the heart of the high-performance market", attracting the best developments in racing due to the best chassis and suspension designs. So it makes sense that Kawasaki would create a machine that could take advantage of this.
The H2 is the first supercharged production motorcycle, although turbocharging was available on some models in the early 1980s.
Information box specs are from Kawasaki unless otherwise stated.
manufacturing
The road-legal Ninja H2 has mirrors instead of the track-only H2R's winglets, and plastic body panels instead of the H2R's carbon fiber panels. The road-legal H2 is said to make 200 horsepower (150 kW), possibly with reduced turbocharger boost compared to the H2R.
The H2 and H2R share a supercharger (H2's lower boost level) and many other components, but head gaskets, cam profiles, ECU-mapped timing, exhaust system, and clutch (the H2R's clutch has two There are additional ones). plate).
For 2017 Kawasaki created a limited edition model with 120 built worldwide:
An individually numbered Kawasaki Ninja H2 Carbon with a custom paint job and carbon fiber upper cowl. In 2017, the classic Ninja H2 was also updated.
For 2018 Kawasaki built a new sport-touring version of his H2, the Kawasaki H2 SX. An option on the base model H2 SX, the feature comes standard on the Kawasaki H2 SX SE with a claimed wet weight of 260.0 kg (573.3 lbs). Throttle bodies, camshafts, crankshafts, pistons, cylinders and cylinder heads have been revised and a new exhaust system aimed at increasing midrange torque.
The intake system and compressor wheel have also been redesigned. A new larger fuel tank, rear trellis frame and panniers add 8.6 kg (19 lbs) to the weight of the bike.
For 2019, the H2 received an update with 15% more power, especially with updates to the intake, spark plugs, ECU and air filter. It also adds a new LED lighting scheme and a special top coat that is said to be self-healing and smooth out minor scratches in warm conditions.
Also new are lighter and smaller Brembo Stylema brake calipers, a new TFT dashboard, smartphone connectivity that provides information on GPS routes, speed, RPM, current gear, fuel consumption, fuel level and odometer. Additionally, the 2019 Ninja H2 SX SE+ features electronically controlled suspension.
engine and compressor
The H2's engine is a 998 cc (60.9 cu in) four-valve in-line four with dual overhead camshafts and a two-speed centrifugal supercharger.
The supercharger is driven by a series of gears and shafts that connect the flywheel to a planetary gear train, ultimately turning his two-speed dogbone-type shaft attached to the impeller. The throttle control is electronically controlled. Centrifugal superchargers have the advantage of generating less heat than other designs, especially scroll or screw superchargers.
Without an intercooler (not on the H2), excessive heat in the intake charge can cause pre-ignition and damage or destroy the engine.
Electronic aids
Electronic rider aids include an anti-lock braking system (ABS), Kawasaki Traction Control (KTRC), Kawasaki Engine Brake Control (KEBC), a Kawasaki Quick Shifter (KQS), an electronic steering damper (ESD), and Kawasaki Launch Control Mode (KLCM).
Aerodynamics
Chassis
The H2 and H2R have a tubular, thin-wall steel trellis frame and a single-sided swingarm, with a traditional sportsbike wheelbase of 1,450 mm (57 in).
Explaining the advantages of Kawasaki's approach to exploiting aerodynamics instead of lengthening the wheelbase, a South African writer said, "It's easy to build stability into a hard-accelerating drag machine with a long wheelbase... but Kawasaki wanted a track-day machine, one that would also go round corners." High speed motorcycles often have long wheelbases. Extra length is added by the extended swingarm on a typical drag motorcycle, and a typical land speed record streamliner has a meters-long wheelbase (3.7 meters for the current record holder, Ack Attack).
