Exhaust Muffler BMW R 12 NINET / R 12 2025 Slip-On Line (SS) S-B12SO25-HISSS

With its neo-retro styling, this exhaust features black-coated conical dual mufflers constructed from high-quality stainless steel with a lightweight titanium link pipe. The exhaust's design and lines have been specially developed to integrate with the motorcycle, and the system is finished with a sandblasted stainless steel heat shield to protect the rider's gear and a laser-etched Akrapovic logo on the muffler for a sleek, refined look. During development, engineers focused on throttle response and rideability, with improved performance thanks to a power increase of 0.9 kW (1.2 hp) and a torque gain of 1.6 Nm, both at 6,200 rpm, compared to a BMW R 12 nineT equipped with a standard system and tested on the in-house dyno. Weight is reduced by 10.6% compared to the standard exhaust, and the Slip-On Line (SS) delivers a deep, sporty sound that meets EC/ECE certification requirements. This exhaust is a plug-and-play installation that requires no remapping. The exhaust system also fits the standard BMW R12.

Optional manifolds for the BMW R12 nine T / R 12 will be available soon.
