Giannelli was born from the passion of founder Giorgio Giannelli, an experienced motocross racer and motorsport enthusiast, who wanted to create a company specialising in the construction of race exhausts for motorbikes. In just a few years, production grew to an industrial level, covering a wide range of exhausts for 2-stroke and 4-stroke engines. Today, the catalogue includes exhausts for road, sport, touring, off-road and scooter motorbikes. Thanks to numerous successes in world championships (over 40 world and national titles), Giannelli has become the leading manufacturer of motorbike sports exhausts.
Giannelli products are made from high quality materials, such as stainless steel, titanium and carbon, and are developed in specific test rooms to guarantee maximum performance, power, emissions, carburetion and engine operation. All production is carried out entirely in Italy, in the town of San Giustino in Umbria.
