MIVV STR-1 Exhausts

The MIVV STR-1 exhaust is a slip-on silencer made only for the KTM 690 Enduro R and 690 SMC R, the brand's single-cylinder enduro and supermoto bikes. It has a body in AISI 304 stainless steel, natural or black, and a 3K twill carbon end piece.

There are two versions by year, one for 2019-2023 and another for 2021-2024, so check yours on the product page. According to MIVV, the ECU does not need remapping, and the sound-deadening packing can be replaced by undoing the screws at the front, which helps if you ride a lot off-road. To be Euro 5 approved it must be fitted with the ACC.041.A1 catalyst, available among the MIVV catalysts, and it does not suit Euro 5+ bikes with the lambda sensor after the catalyst. The 690 also has Oval versions in titanium and black, under MIVV.
