Removing the O2 sensors from the header because of the use of Rottweiler Performance fuel dongles or a Power Commander V?
RALLY-MOTOR created the Titanium 12mm O2-sensor plugs specially for the KTM 690-1050-1090-1190-1290 and Husqvarna 701 bikes. No cheap stuff, but specially designed and produced for the bikes mentioned. They have a lenght of 15mm and include a crushring. Also they received a special blue-flamed treatment that looks really cool.
Do you awn a KTM 950-990 or RC8? Please buy the 18mm O2-sensor plug.
