The Rieju MRX SMX is a Rieju off-road model with a 125cc displacement, built between 2002 and 2008.
On this page you'll find sport exhausts for the Rieju MRX SMX from GPR and Giannelli.
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. Giannelli, born in 1985 from the passion of Giorgio Giannelli and made in San Giustino, Umbria, produces exhausts for 2-stroke and 4-stroke motorcycles and scooters.
