SPARK black titanium exhaust silencer with carbon end cap for the 2019–2023 BMW R 1250 GS.

+ 2.5 HP
62% weight reduction

 The result of Spark R&D’s extensive research into combining aesthetics and design with the volume and technical specifications required by the latest regulations on pollutant emissions was tested for months by Stefano Sacchini of Adventure School.
The durability test was easily passed thanks to a carefully selected combination of extremely lightweight materials, such as carbon fiber for the end cap and titanium used for all other components, for a total weight of 1.9 kg for the complete slip-on, resulting in a 62% weight reduction.
Performance is optimized exactly where it is needed in the mid-range, with +2.5 hp at 4,500 rpm simply by installing the Spark silencer on the original header, with the motorcycle in completely stock configuration.
