Responding to Regulations

All the approved products are developed with each regulation.

In recent years, emission regulations have been tightened for aftermarket mufflers on motorcycles on public roads, as well as for noise. The regulations also vary depending on the year, displacement and destination.
Yoshimura Cyclone is developing products that not only improve performance, but also meet the strict regulations as part of its efforts to address environmental issues, and the JMCA plate is proof of this. All Yoshimura cyclones currently manufactured for use on public roads are fitted with this plate.
