My love for the KTM 790 Duke has been well documented on MO, but the reality is that had KTM been a little less tight-lipped when I was laying down my hard-earned cash for the bike, I might never have owned it. Instead, an 890 Duke R would probably be parked in my garage. That doesn’t lessen my attachment to the 790, but it helps to explain my desire to squeeze as much power out of the parallel-Twin as I can, while maintaining its social acceptability on exhaust sound. (OK, maybe being mocked in the comments when the Akrapovic slip-on resulted in slightly lower peak power has a little to do with my search for power, too.) Regardless, my unspoken goal for my performance modifications has been to get as close as possible to a stock 890’s mid-range power. From the moment Rottweiler Performance released its Rally Edition Full Intake System for the 790/890 Adventure, I’ve been salivating at the prospect of installing an adapted version on my Duke. Well, with the release of the Rottweiler Performance Intake System for the KTM 790/890 Duke, that wait is over, and man, does it kick some butt. 

Back in the era of my misspent youth, things used to be so much simpler. You’d take your new motorcycle home, bolt-on a “Closed Course Only” aftermarket exhaust, and (if you were smart) install a jet kit in the carburetors. The result was significant power gains and weight loss. Today, things are a little more complicated. Carburetor jet kits are illegal in some states, and the OEMs are making it tougher for EFI piggyback systems to alter what the EPA dictates your air/fuel tuning should be. Additionally, it is much more difficult to get aftermarket exhausts in some places.
