As GSX-R125/S125 carry super sports DNA, Yoshimura developed GP-MAGNUM with our race experience and know how.

Our GP-MAGNUM brings maximum performance for this little monster.
Comparing stock exhaust, torque and HP increases in most of ranges especially mid to top range.
The engine runs to rev without stress.

Weights are reduced by 2.1kg* that is about 45% weight of the stock silencer (*Carbon cover type).
