Extra Info

Our Exhausts are manufactured to give maximum power without the need to alter the fueling but, if you have an aftermarket air filter and/or a de-cat, then having the bikes fueling looked at will always compliment the engine’s performance and efficiency.

To Make sure that you are shopping for the correct Model exhaust here is some information about this model.

Below is information on the related Sportsbike Ninja H2R

The Kawasaki Ninja H2 is a “supercharged supersport” class motorcycle in the Ninja sportbike series, manufactured by Kawasaki Heavy Industries, featuring a variable-speed centrifugal-type supercharger. The track-only variant is called Ninja H2R, and it is the fastest and most powerful production motorcycle on the market; it produces a maximum of 310 horsepower (230 kW) and 326 horsepower (243 kW) with ram air. The H2R has 50% more power than the fastest street-legal motorcycles, while the street-legal Ninja H2 has a lower power output of 200 hp (150 kW)–210 hp (160 kW) with ram air.

H2R top speed

2015
In June 2015, TT race competitor James Hillier rode a Kawasaki H2R as an inter-race demonstration lap, at near-race speeds, using normal Superbike slick race tires, around the 37​3⁄4-mile road course, leading to a roads TT record of the highest top speed attained in the Isle of Man by a motorcycle. The top speed of “over 206 mph” (332 km/h) on the Sulby Straight was recorded on Hillier’s personal Strava GPS smartphone app for cyclists.

2016
On June 30, 2016, Kenan Sofuoglu, a five-time world champion Supersport circuit-racer, made a top speed attempt. Kawasaki supplied a stock H2R, other than special-formula rubber tires developed by Pirelli for the top speed attempt to withstand extremely high speeds, and the bike was supplied with race-grade fuel. Sofuoglu was supplied with a special one-piece leather suit to enhance aerodynamics for his record attempt.

This attempt, with the Turkish president in attendance, was made across the then-newly completed Osman Gazi Bridge, the fourth-longest in the world at just over a mile and a half. Kawasaki quoted the H2R maximum speed to be 380 kilometers per hour (240 mph). After training and preparing for four months, a speed of 400 kilometers per hour (250 mph) in just 26 seconds was claimed by a video-recording of the bike’s dashboard display.

The speed was not officially confirmed or independently verified. No fixed point optical sensors for distance/speed calculations, chronometers, or hand-held devices were used, and later with a theoretical calculation,[29] of the distance, he traveled in 26 seconds on the 8,799-foot-long (2,682 m) bridge. Cycle World’s Kevin Cameron had calculated two years earlier than with the right gearing, the H2R’s engine power could theoretically overcome aerodynamic drag up to 250–260 miles per hour (400–420 km/h).

The street-legal Ninja H2 has rear-view mirrors in place of the track-only H2R’s wings. It also has plastic body panels in place of the H2R’s carbon fiber. The street-legal bike is said to make 200 horsepower (150 kW), probably with reduced supercharger boost compared to the H2R. The H2 and H2R share the supercharger (with a lower boost level on the H2) and many other components, with the exception of the head gasket, cam profile, and timing with ECU mapping, and exhaust system, as well as the R’s clutch, has two additional plates.[1] Cycle World recorded a
1/4 mile time of 9.62 sec. @ 152.01 mph (244.64 km/h) with a 0 to 60 mph acceleration at 2.6 seconds and a top speed of 183 mph (295 km/h). Kent Kunitsugu, editor for Sport Rider magazine, competing in a land-speed racing event in Mojave, California at the Mojave Air and Space Port airfield in the Mojave Magnum land-speed racing, took a Ninja H2 with just a few bolt-on performance parts adding over 70 horsepower and achieved a top speed of 226.9 mph (365.2 km/h).

For 2017, Kawasaki made a limited-edition model with 120 units produced globally: the individually-numbered Kawasaki Ninja H2 Carbon with special paint and carbon-fiber upper cowl. For 2017, the standard model Kawasaki Ninja H2 is also updated
For 2018, Kawasaki made a new sport touring version of the H2, the Kawasaki H2 SX, with a claimed wet weight of 256.1 kg (564.5 lb). Features that are options on the base model H2 SX come standard on the Kawasaki H2 SX SE, which has a claimed wet weight of 260.0 kg (573.3 lb). With revised throttle bodies, camshafts, crankshaft, pistons, cylinder, and cylinder head as well as a new exhaust system aimed at increasing mid-range torque. The intake system and supercharger impeller were also redesigned. A new larger fuel tank, rear trellis subframe, and panniers increase the bike’s weight by 19 pounds (8.6 kg).

For 2019, the H2 received an update with 15 percent more power from updates to the intake, plugs, ECU, air filter, and more. There is new all LED lighting and a special topcoat on the paint that is claimed to be self-healing, which in warmer conditions, is able to smooth over small scratches. Also new are lighter and smaller Brembo Stylema calipers, a new TFT dash, plus smartphone connectivity that gives vehicle information about GPS route information, speed, rpm, gear position, fuel mileage, fuel level, and odometer. In addition, the 2019 H2 SX SE+ version features Electronic Control Suspension.

Speed record
On August 12, 2018, rider Shigeru Yamashita with an unofficial team of Kawasaki employees (known as Team 38) set a 202.743 mph (326.28 km/h) speed record in the Southern California Timing Association (SCTA) P-PB 1000 class for under-1,000 cc displacement production supercharged motorcycles with limited modifications at the Bonneville Speedway. On August 15, he broke his own record with a new speed of 209.442 mph (337.06 km/h).

Construction
Kawasaki selected the literbike platform for its top-of-the-line Ninja H2-H2R model, rather than continuing with the higher-displacement hyperbike Ninja ZX-14. Kevin Cameron explained that the liter-class is “the center of the high-performance market”, attracting the best development in racing, with the best chassis and suspension design, so it made sense for Kawasaki to create a machine that could leverage this.

Engine and supercharger

The H2-H2R engine is a 998 cc inline-4, four-valve, dual overhead cam design with a two-speed, centrifugal supercharger. The supercharger is driven by a series of gears and shafts connecting the flywheel to a planetary drive, finally spinning a dog-shifted two-speed shaft attached to the impeller. Rider control is throttle by wire.

It is the first production motorcycle with a supercharger, although turbochargers were available on some models in the early 1980s.

A centrifugal supercharger has the advantage of generating less heat than other designs, especially scroll-type or screw-type superchargers. Excess heat in the intake charge can cause pre-ignition that will destroy the engine.

Electronic aids
Electronic rider aids include an anti-lock braking system (ABS), traction control (KTRC), engine braking control (KEBC), Kawasaki quick shifter (KQS), electronic steering damper (ESD), and launch control (KLCM).

Aerodynamics
The front fairing of the Ninja H2R incorporates stub-wings which are made of carbon fiber, just like the rest of the H2R-exclusive bodywork. They may be aerodynamic devices designed to create a low-pressure zone to help move cooling air through the engine bay,[56] or to produce downforce at high speed, or to provide straight-line stability in a short-wheelbase sportbike chassis.

Chassis
The H2 and H2R have a tubular, thin-wall steel trellis frame and a single-sided swingarm, with traditional sportbike wheelbase.

Explaining the advantages of the Kawasaki 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 bike; a typical land speed record streamliner has a meters-long wheelbase (3.7 meters for the current record holder,
