The new Kawasaki ZX-4RR sport bike is one special machine. Engineers at Kawasaki set out to develop a 400cc inline four-cylinder engine built for high performance, and they delivered.
For this special machine, we used our AT2 muffler to develop a Street Series Works Finish slip-on, giving power to the 16,000 + RPM's of the new Kawasaki powerplant. The AT2 came through in performance, sound, and weight savings. An increase of 3% bumped up HP and torque was bumped up as well, adding 4.3%. Our mission of adding power and torque throughout the entire spectrum was accomplished. Our AT2 Slip-on removed 4.5 pounds from the stock formation.
The sound of this inline four at 16,000 rpms with our AT2 is simply something that must be experienced in real life. True music! Finally, the styling of the AT2 can't be beat. It's now iconic matte carbon fibre end cap and heat shield complement the lines of the ZX-4RR to perfection.
All Street Series systems are Slip-on / Bolt-on applications that do not require tampering with the vehicle's emissions control system yet still deliver that special spirit the world has come to expect from the legendary company known as Yoshimura. Street Series applications cover all of the iconic profiles that Yoshimura has become famous for. From the legendary tri-oval profiles to the refined ALPHA mufflers, and even our R-55 angular masterpieces. Our Street Series exhausts offer street-legal options for almost everything on two wheels.
New Yoshimura Works Finish takes on a unique colouring after it goes through a heat cycle on the motorcycle that looks much like the titanium works components our factory racers use.
