SPARK black titanium exhaust silencer with carbon tip for BMW R 1250 GS from 2019 to 2023.

+ 2.5 HP
62% weight reduction

The result of Spark R&D's extensive research to combine aesthetics and design with the volumes and technical features required by the latest emissions regulations was tested for months by Stefano Sacchini from Adventure School.
The durability test was easily passed thanks to a carefully crafted combination of extremely lightweight materials such as the carbon fiber tip and titanium used for all other components, totaling 1.9 kg for the complete slip-on, allowing a 62% weight reduction.
Performance is optimized exactly where needed at mid-range, with +2.5 HP at 4,500 rpm simply by fitting the Spark silencer on the original collector, on the bike in completely original configuration.
