Cyclone developed for the 2017 CRF250RALLY / L / M which complies with the new regulations by reviewing the intake and exhaust.
The silencer design is based on US Yoshimura's motocross "RS-4" which is used in AMA Supercross etc. and adapted to Japanese standard.
This Slip-On Cyclone is designed to be used with the stock exhaust system.This exhaust is designed to meet the stringent Japanese regulations and provides a significant increase in power output in the low to mid RPM range for a more powerful acceleration.
The sound quality is also pursued so that you can experience the joy of manipulation with your sense of hearing.The single engine's crisp exhaust sound is combined with a mild sound quality to provide a light acceleration feel.
The cone end is made of carbon material to reduce weight and create a sport design.
On the front side of the silencer, laser marking of "RS-4J" is applied with the emblem, and on the back side, the emblem is also applied.
In addition, by using the same mounting position & diameter of the exhaust pipe and tail pipe as the stock exhaust, customers who have a slip-on exhaust can purchase the Yoshimura exhaust pipe only and change the specifications to the full exhaust type which is characterized by increased power in the mid to high RPM range.
