Introducing Yoshimura AT2 (Alpha Taper 2) muffler! An iconic muffler profile with original design cues.

We couldn't think of a better bike to debut our new AT2 than the new KTM 890 Duke R. With its edgy lines, its compact naked bike stance and an all new thrilling torque monster motor, the AT2 is a perfect match.

A cousin of the Alpha Taper muffler, AT2 has new styling with an all-new matte carbon fiber end cap and heal guard and stainless boot guard as well as an all new faceted inner end cap assembly. It just looks fast standing still!

The exhaust note that the AT2 delivers is second to none. One crack of the wrist and the 890cc twin thunders like it's ready for playtime. Power and torque are up considerably to give the DUKE even more prowess when things get sticky.

Proudly made in the USA!

  • Stock muffler weight: 7.4 Lbs. vs Yoshimura AT2 Slip-on weight: 4.8 Lbs.

William ★★★★★

This AT2 slip-on gave my Duke a much deeper, more aggressive bark without being obnoxiously loud on longer rides. The install was straightforward, and the tapered stainless muffler looks sharp against the bike's lines.

Aurora ★★★★★

The AT2’s stainless finish is holding up great after a few hundred miles, and the sound is deeper than stock without being obnoxious on the highway. Install was straightforward on my 890 Duke R, but the taper design really stands out in person.

Julian N. ★★★★★

The taper on this muffler gives the bike a really aggressive look that matches its character perfectly. It sounds deeper than stock without being obnoxious on longer rides, and I noticed a solid improvement in throttle response.
