Not all new just refined. The 2020 KTM Super Duke R with its massive 1290cc v-twin engine was begging to let more ponies and torque rip. That's where we come in.
We could not wait to roll up our sleeves and get the brand new AT2 slip-on system on this beast. Available only in titanium, the new edgy look and tuned sound of the AT2 is perfect for the new Super Duke and compliments it in every way. With its faceted titanium inner cap, matte carbon fiber end cap and heal guard, saving 3.7 pounds, the AT2 delivered.
In the performance department the 1290cc engine breaths fire now thanks to the AT2 adding a nice boast of 4.75% gain in max HP and 7.2% gain in max torque. This new AT2 checks all the boxes for those that really want something special for their Super Duke. Now you have the power!
The AT2 is proudly made in the U.S.A.
