The UM DSR 125 is an UM off-road model with a 125cc displacement, built between 2018 and 2023.
On this page you'll find sport exhausts for the UM DSR 125 from GPR and Arrow.
A sport exhaust replaces the stock silencer with a lighter component, often in stainless steel, titanium or carbon fibre, reducing the bike's weight and freeing up the engine's power delivery compared to the original system.
GPR is based in Cerro al Lambro, near Milan, and makes its titanium and stainless steel silencers and headers in-house; it races in MotoGP, Moto3 and the World Supersport Championship. Arrow, founded in 1985 by Giorgio Giannelli, builds its exhausts in stainless steel, titanium and carbon in San Giustino, Umbria, backed by more than 40 world and national titles.
