A scarf to unleash your potential! Yoshimura “Mechine Curved Titanium Cyclone Duplex Shooter”

▲for SUZUKI KATANA

The dimensions of each part are of course specially designed. However, the newly developed cyclone for the KATANA/Z900RS by Yoshimura was designed to muffle sound and Both mechanisms use a sub-silencer and bypass pipe to achieve both power.

You can fully enjoy the inherent qualities of the engine.

When I interview people who love old bikes, it's not uncommon to hear them say, "Today's bikes are boring. I don't necessarily agree. It's not fair to talk about modern motorcycles, which were born under the premise of emission control, on the same scale. I don't think so. Nevertheless, after experiencing the two bikes we tested, I'm sure it will change the way you look at bikes nowadays, even if you're an old-school fan. There is none. KATANA and Z900RS that Yoshimura worked on are both based on the GSX It's as exciting a ride as the 1100S Katana or Z1! From.

What is Duplex Shooter?

The "Duplex Shooter" has a sub-silencer that also exhausts air from the sub-silencer. Unique mechanism. The Z900RS's hand-curved straight cyclone was used for the first time on the Z900RS, and the two new models follow suit. The black painted stainless steel sub-silencer measures 105mm in diameter by 230mm in diameter and is designed primarily to muffle sound But it also has a significant effect on the power characteristics.
Exhaust from the expansion chamber too!

The reason I felt that way is because I was able to use the X-Tread step, which is very responsive, and the latest aftermarket parts The most important element is the muffler. On the other hand, the newly developed Yoshimura machine-curved titanium cyclone Duplex Shooter ( Cyclone) experience, STD's have suppressed their true potential, and the capable hawk hides its claws. Specifications..........

That said, the sound of the cyclone while idling and cruising is surprisingly subdued, rather than the STD's. It's enough to make me feel wild. How to understand this area is different for each person, but for me, I think that titanium, a material with a disadvantage for sound deadening, is a good choice. I am amazed that he was able to build such a gentle sound while using a short silencer. I think so. By the way, according to the development team, the sub-silencer and the exhaust pipe were designed to have a good balance between noise reduction and power. They say the bypass pipe plays a big role.

So when do you get a better feel than the STD, that is, of course, the throttle This is when you open and close the throttle aggressively. Although there is not an extreme difference in the power curve, the Cyclone-equipped vehicles have a higher blow up speed than the STD. It's much faster, and in the area before the red zone, it accelerates so fast that you can't follow it. You can feel it. Zuvah at low rpm! The high-pitched, high-pitched tone of the Cyclone is something you just can't get with an STD.

In addition, the smoothness of the engine's emblems when decelerating and the lightness of the car's handling are other benefits of the Cyclone-equipped vehicle, but what impressed me the most during this test drive was how the engine responds to the way it opens the throttle.

The engine responds to the way you open the throttle with a little bit of force and the way it reacts to the way you open the throttle with a little bit of force. The same is true for Cyclone-equipped cars. But the response of the Cyclone-equipped car is gentler than the STD when you open it up, and it's not as easy as the STD. When you open it up, the torque is sharper and more powerful than an STD, and this is a true parallel 4-cylinder! You can feel the roar of the rider. I thought to myself, "I guess Yoshimura knows how the rider feels.... I'm seriously impressed.
The response of the engine to the operation became obedient, so when entering a corner, the body is lowered forward. It's easier to control the attitude with the throttle work, such as by doing, or by raising the body slightly while turning. This is one of the beauties of the Cyclone-equipped cars. In case you're wondering about the elements mentioned at the beginning of this article, we'd like to add a note of caution: the Yoshimura KATANA and Z The 900RS doesn't look like an old car. Nevertheless, the engine's original qualities can be enjoyed to the fullest, as if the ostracism had been removed. The Cyclone-equipped vehicles have a similarity to the older vehicles in that they offer a full range of sport riding experience. You can feel the atmosphere.

The photo shows the Z900RS. Both cars have the 1/2 and 3/4 exhaust pipes connected. The aim of this mechanism is to improve the sound deadening and output characteristics as well as the sub-silencer. The outer diameter of the pipe is 25.4/27mm.

Yoshimura's first full extractor for KATANA was initially developed with a simple, old-fashioned configuration. Start. Nevertheless, in order to meet emission and noise regulations while achieving the ideal output characteristics and sound quality, a huge He said he needed a silencer, and the looks in that state were not flattering. . The solution to these problems is a sub-silencer and bypass pipe.

The power curve (red) of the Cyclone-equipped vehicles exceeds that of the STD in all areas. The biggest difference is in the mid RPM range.

You can also choose from a selection of hardened exhaust pipes.

The color of the exhaust pipe and tailpipe is titanium, but you can also choose the Fire Spec option for 16,500 yen more.

The straight cyclone on sale is said to be slightly less than an STD in the mid-range, but the new The cyclone outperforms the STD in all areas, with a 38mm diameter exhaust pipe and 54mm diameter tailpipe. The Z900RS has the same specifications as the KATANA, but is slightly longer. The specifications and price are the same as KATANA.

Full of parts under development, with more to come!

Although we focused on the muffler in this article, the current Yoshimura is designed for the Katana/Z900RS. We are developing a variety of parts. The X-CONTROL low handlebar kit for KATANA, which is about to go on sale, and FRP cowl and tank cover, created in collaboration with ETEC to enhance the quality of the Z900RS. The carbon fiber exterior is sure to attract a lot of attention.

YOSHIMURA KATANA - no interference even with a low handle!

FRP Exterior

If you install the X-CONTROL on the STD, it will make contact with the exterior, but you can avoid the handlebars' trajectory and We are developing the original cowl and tank cover to have the same cut-off angle as the STD. The ducts and "Yoshimura" embossed letters are sharper than the STD.

Handle KIT X-CONTROL

▲We can cut to the full lock!

The X-CONTROL has an original structure, which makes it difficult to install a separate handle on the KATANA. This part is designed to reproduce the ride quality of the former GSX1100S Katana. Exquisite angle of squeeze and the angle of drop is a characteristic of Yoshimura who knows everything about katana and katana. The upper body leaning forward is not so tight.

The carbon fiber parts for the Z900RS, which are scheduled to go on sale in the near future, have all been jointly developed with Altec This is a good example. There are many different manufacturing methods used to make Atech's carbon parts, but Yoshimura's carbon parts are made with a very high degree of weaving. Larger setting. It builds a creative texture that is different from existing carbon covers.
