With the GPR Deeptone, the name says it all! Especially with this version, with carbon rear silencer, the sound is very dull and dark due to the special design. In addition, the GPR Deeptone offers a simply unique look on the Yamaha MT 125. As with all other exhausts, GPR has incorporated all the experience from the Moto GP and SBK racing series. In addition, the exhaust offers an unmistakable high quality at a fair price. All metal parts are either aluminium or AISI 304 stainless steel. Everything is of course rustproof!
