At DMG Motorsports, we present the YOSHIMURA RS-3 Full System Exhaust — a race-bred, purpose-built exhaust engineered specifically for the Honda Monkey 125 platform. This Race Series system (SKU 960-2272 / UPC 0840025907744) pairs Yoshimura's legendary RS-3 muffler design with a stainless steel header and tail-pipe to deliver a meaningful jump in performance along with the unmistakable Yoshimura look and sound. Yoshimura reports the full system boosts max HP by 7.3% and max torque by 3.1% over stock, while the complete RS-3 stainless full system weighs just 5.5 lbs compared to the stock full system's 11.2 lbs — a significant weight savings that sharpens handling on this compact platform. Proudly made in the USA, this system was custom developed to fit the details of the Monkey, right down to a dedicated core baffle and heat shield. Built as part of Yoshimura's Race Series lineup, these exhaust systems are designed with nothing but power in mind and are developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide. This system is intended for closed-course competition use only.
