Product Information
R-77S delivers a race-derived sound quality with a comfortable and powerful sound
The R-77S is a downsized version of the R-77 used for US Yoshimura racers and has the functional beauty of a race-derived silencer. It has both high sound deadening performance and high performance, and it has a comfortable and powerful exhaust sound that complies with the strict volume regulations. With dry carbon end caps and black anodized aluminum silencer bracket, it achieved both high performance and low cost, while paying close attention to detail.
With ease performance that continues until the rev limit
The R-77S Cyclone effectively draws on the output of the Ninja 250/400 twin-engine to deliver a sporty engine and exhaust sound with powerful acceleration and a sporty response to stimulate the sporty spirit of the rider, while complying with volume regulations.
Furthermore, along with the engine output that exceeds the STD in almost the entire area and extends to the rev limit with ease, the weight reduction (*) of 49% for the Ninja250 and 51% for the Ninja400 brings riding performance better than the power graph.
