The answer to the limiting exhaust valve is here. The 2017 KTM Super Duke 1290 R and 16+ Super Duke GT both contain a flapper valve in the exhaust system that can make things extremely difficult when wanting to install the aftermarket exhaust of their choice. Even worse, if you attempt to remove the servo and cables from the bike physically, the computer will realize this through it's series of checks when the bike is keyed on and put it into a limp mode which will not allow the rider to accelerate past 6000 RPM.
With our billet aluminum 'Servo Stopper', you can remove all of the cables and valve from the system by simply installing this small device that fools the servo when going through it's initial checks that the cables are still attached and everything is functioning perfectly.
Now you are free to install the exhaust system of your choice! (Click the link to see what is available)
Note: The 2017 Super Duke 1290 WILL work with the current and past models of exhaust systems. While the muffler mount was moved rearward, they simply made a new passenger peg for that and the 13-16 threaded mount location is still on that bike and available for use on the 2017 Super Duke R with pre 2017 exhaust systems that used that mount. Low mounted shorty exhausts do not need this mount at all.
