The Arrow Pro-Race Racing full exhaust for Yamaha R125 2025-2026 is a system developed to deliver the highest level of racing performance, lightweight construction, and sporty sound for Yamaha’s lightweight supersport motorcycle. Directly derived from Arrow’s MotoGP and Supersport racing experience, this complete exhaust system is one of the most aggressive and exclusive upgrades available for riders looking to completely transform the character of the Yamaha R125.
The system combines a racing stainless steel header with an Arrow Pro-Race muffler featuring a compact MotoGP-inspired design. The Pro-Race line was developed from technology used in top-level motorcycle racing and combines a conical body with a cylindrical 98 mm outlet section, creating a distinctive racing appearance.
The muffler features a refined stainless steel end cap, adding both technical value and premium racing aesthetics. The lightweight construction significantly improves:
The decat racing configuration allows the Yamaha single-cylinder engine to express a much more aggressive character compared to the stock exhaust system.
The system produces an incredibly deep, metallic, and aggressive exhaust note, directly inspired by MotoGP racing machines. The distinctive Pro-Race muffler shape creates a highly recognizable and engaging racing tone.
The compact dimensions and conical-cylinder layout make this exhaust perfect for enhancing the supersport styling of the Yamaha R125, visually lightening the rear section while delivering a true high-end racing appearance.
As this is a non-homologated racing exhaust system, Euro5+ motorcycles may trigger the MIL / Check Engine warning light after installation.
