Produces a heart-pounding sound even when idling!
The GP-MAGNUM features a traditional round silencer that blends in with the styling of the CT125 Hunter Cub. It is assembled with unique parts throughout, such as Yoshimura’s original dimple rivets and hollowed-out rivet bands.
This muffler delivers ample torque from the moment you open the throttle, providing a relaxed ride feel in the mid-to-low speed range while contributing to sporty riding up to the high speed range.
It also produces a pulsating sound even when idling. The higher the rotation speed, the more dynamic and explosive the exhaust note becomes. The silencer cover and glass wool can be remade to support the user’s motorcycle lifestyle. There are four types of silencer covers to choose from to suit your preferences and budget.
[What is EXPORT SPEC?]
The EXPORT SPEC is a specification that meets the requests of discerning overseas users. While prioritizing performance, it is characterized by the artisanal TIG (welding) burnt color and processing marks that remain in the original finish.
By using highly durable stainless steel as the material, Yoshimura’s unique design and style are realized while also achieving a price that offers excellent cost performance.
