SEFIS Exhaust Reduction from 51mm to 61mm

The SEFIS MOTO exhaust reducer connects a 51mm exhaust downpipe to a silencer with a 61mm inlet diameter. This adapter is designed for installing specific R-Tech exhaust models. It creates a precise and tight seal between the downpipe and the silencer, which is crucial for the correct operation of your motorcycle's exhaust system. The reducer is designed for the R-Tech RK, RP and ST models.
