Description

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.

    Amazing slip on!

    I was a little nervous purchasing this exhaust for my bike because it says its for a 20-21 and my Duke 890 is the 2023, but this pipe fit like a glove and was about a 5 minute install. and with the initial cold start it sounds amazing not to mention I put it on the Duke with 25 miles on the bike! then after installing I took a ride around town and put 10-15 miles on it and thoroughly enjoyed the sound it made it drastically made the bike sound like the old KTM Super duke 990! Great Job Yoshi R&D I hope the fender eliminator goes on just as smooth!

    2023?

    Can it be fit on a 2023 ? Only 2020, 2021 are mentionned on your website.

    Sorry.... We have not verified if it fits 2023 yet.

    It Works!

    Looks great, sounds great, and improves performance substantially! I'm running RP power plate, Coober LM device, and the AT2 on my 890 Duke base model. Rolling start drag 40mph to 80mph in third WOT improved by .7 seconds vs. stock silencer. 4.45s vs. 3.74s. Average of seven runs with each setup. Times measured with GPS Race app, same day, same location, same conditions. This has far exceeded my expectations, I did not expect to see a consistent measurable difference in performance. Highly recommended.

    Question on passenger footpegs

    I have this installed without the passenger foot pegs in my 890 duke R. Can this be installed together with the passenger foot pegs? Thnx

    Just confirmed this should fit with OE foot pegs.
