The Ninja 1000 SX with its racetrack roots has been developing some of its own roots now for touring and weekend trips. Yoshimura is here to refine performance.

With a solid base 1043cc inline 4 cylinder engine, this new Ninja is radically smooth! One of the areas we focused on was to give the Ninja more giddy up on top and our Alpha slip- on delivered! With an increase of 4% max horsepower and 4.7% max torque, it's safe to say the Kawasaki Ninja 1000 SX is even more fun to ride.

The sound note that the Alpha delivers has even been taken into consideration. Nobody wants a big drone sound in their helmet after a nice ride. The Alpha is ear pleasing while letting others know you're there. We saved some weight too! The Alpha carbon sleeve version removes almost 6 pounds of weight from the back of the new Ninja 1000!

The Alpha slip-on system is proudly made in the U.S.A.

  • Stock muffler: 11.4 Lbs. VS Yoshimura carbon fiber Alpha Slip-on: 5.5 Lbs.

Eva W. ★★★★★

The carbon fiber muffler looks incredible on my Ninja 1000SX, and the stainless mid-pipe gave it a much cleaner profile than the stock can. Sound is deeper and more aggressive under throttle, but it's not obnoxious on long rides—exactly what I wanted for weekend trips.

Victoria ★★★★★

Lost a bit of weight off the rear, and the carbon fiber muffler looks fantastic against the silver frame. The tone is deep and rumbly without being obnoxious on long highway stretches.

George ★★★★★

I mounted this on my 2021 1000SX in about 20 minutes with basic tools—the carbon fiber muffler looks incredible and the sound is deep but not obnoxious on the highway.
