It is worldwide that there is a thing to lose if there is a thing to get.
However, the Yoshimura developed Muffler for Monkey 125 had qualities that exceeded normal with every element.
The engine breathes smoothly and pleasantly
Speaking of Yoshimura, a large displacement sports. Although the world may have such images in the world, the company has been actively involved in 4 stormi since '70' s, in recent years the parts corresponding to Monkey 50, Ape, Grom, etc. are good sales over the long term Are recorded.
Of course, regarding Monkey 125 which began selling this year, Yoshimura plans to release various parts, the development of which is progressing as the first step is the GP magnum which we introduce on this page.
Pursuing 'Yoshimura' as sound and looks
Structurally, if the exhaust pipe draws a U shape beneath the engine, against the normal of the upsilencer, the GP Magnum is a straight down type of exhaust pipe. When saying what kind of impression I took in comparative test drive with these two cars ... ....
•GP-MAGNUM
As a result of pursuing Yoshimura's exhaust sound and looks against the normal type of up type, the company's first muffler selected the down type. Measured weight is 5.04 kg of steel normal, whereas the GP magnum of stainless steel + carbon / titanium is 2.3 kg. It seems that this difference is related not only to the material but also to the length of the exhaust pipe.
•NORMAL
Release monkey's original character
•We introduced taper pipe considering exhaust pulsation between φ 32 mm exhaust pipe and φ 50 · 8 mm tail pipe. Structure different from STD Unlike STD (pipe used is φ22.2 / 25.4 / 28mm) earning pipe length under engine, GP-MAGNUM adopts a straight structure.
Structure of an evacue different from STD
•Unlike STD (pipe used is φ22.2 / 25.4 / 28mm) which earn tube length under the engine, GP-MAGNUM adopts a straight structure.
It exceeds normal over the whole area
•Although the difference on data is less than 1 ps, GP-MAGNUM demonstrates the power surpassing STD in the whole area.
•Laser marking the product name to the silencer end of φ 90 mm × 250 mm. After examining several kinds of inner pipe, φ 50.8 mm was chosen.
• The T-shaped stay made of stainless steel lost wax fixes the silencer to the car body. Yoshimura 's logo is also engraved on its surface.
It was a victory of Yoshimura. Even if it says, normal is also not bad for a single ride. However, after experiencing the beauty of GP Magnum, such as heavy and crisp exhaust sound, good response to throttle operation, sharp and pleasant elongation in the high revolution range, vibration lessening throughout the area, normal It seems as if he is suppressing the original qualities, especially around the high speed range. In other words, Yoshimura car breathed smoothly in every area, the engine seemed comfortable.
The reason why I was surprised at the GP Magnum was that in spite of the structure that seems to be important for the high revolution range, the torque in the low and middle revolution range was secured exactly and the throttle opening was kept almost constant, chilling It was a pleasant cruise. In this area, Yoshimura betrayed the prediction greatly though I thought that the narrow and long normal was more advantageous.
Among them, I was interested in the pleasures of cruising, and this characteristic that I can enjoy the sense of beating beyond 125 cc is sure to be able to keep running for long distances without getting tired.
Not only can you enjoy running more sporty than normal, you can taste better quality feeling. That is my impression of the GP Magnum, as I who witnessed Yoshimura's technological capabilities in the first step, I am very looking forward to developing the parts for the company's Monkey 125 in the future.

Correspondence to tuning has also been incorporated
While pursuing absolute performance, our muffler develops in mind that everyone can enjoy it with ease. Especially when pursuing performance for a single cylinder, it tends to be a thoroughly impressed feeling, so for the monkey 125, I was conscious of the kindness and mildness considerably. Of course, as with existing monkey 50, it is designed considering correspondence with tuning engine.
•Production is in Thailand! The muffler for Monkey 125 was produced in Yoshimura Asia in Thailand, which began operation from September 17th. The company is the third base for the Yoshimura group, following Japan and the United States.
"Up Type" is also under development!
Yoshimura releasing a variety of 4 stomini parts, but Monkey 125 is considering similar development, and now is developing an up type muffler. Slip-on (photo) and full-fledged are going to appear.
