Proximity exhaust noise: 87db/4250rpm Noise at acceleration: 74db
■Is stock CYGNUS X too slow? The CYGNUS X is highly popular as a commuter bike and for modifications No matter where you accelerate from, it accelerates smoothly and is easy to ride, but in other words, it lacks punch. It's been listed as one of the top modified vehicles in moped magazines, and its sporty riding style is appealing, but it is said that CYGNUS X is slow Many users seem to feel that way when they look at review sites on the Internet. Don't get me wrong, CYGNUS X is slow in stock form. The reason why you feel the Cygnus X is slow is because of its slow start. Compared to its rivals such as the Address V125 and the PCX, it has a noticeably slower start, and when waiting at traffic lights, it will always fall behind.
■Having focused on the total balance. The theory behind sports exhausts is to make it easier for the exhaust to escape and to improve acceleration at high rpm. However, in the case of CYGNUS X, as mentioned above, the exhaust is slow to start out, so a exhaust that follows the theory will be difficult to ride. Therefore, World Walk focused on the total balance of the exhaust, and aimed at the exhaust which can run comfortably in the town where there are many stop & go, instead of the race specification exhaust which runs without dropping the rpm.
■It is a exhaust that increases power in all areas. The data of the power graph is the power data which World Walk borrowed from the chassis dynamo machine at Driver's Stand Wako on 2013/11/13. The vehicle used was CYGNUS X 3rd.*This is the newer SE44J. As you can see, the power curve of the red Power Silent exhaust is superior to the stock exhaust in all areas. The result of the dynamo is one of the confidence of World Walk, but the most important thing for us is "feeling". When the Power Silent Exhaust for CYGNUS X is installed on the vehicle, the first thing you will notice is the improved response. When you open the accelerator pedal, the vehicle accelerates quickly and the response is very good, which is much easier to drive than the stock condition.
The Cygnus X is equipped with a device called AIS.
When installing an aftermarket exhaust, some exhausts are recommended to be removed easily because they have no effect on the exhaust gas density. The Power Silent Exhaust for the CYGNUS X SE44J is designed to be compatible with the AIS system to reduce the exhaust gas concentration. Furthermore, a platinum coated honeycomb metal catalyst is placed in the exhaust pipe. It is a device to reduce the density of exhaust gas, but by placing it in the exhaust pipe, it becomes a moderate exhaust resistance and succeeds in getting power at low speed.
■The exhaust sound is gentle at idling and during acceleration In the JMCA riding noise test at acceleration, the proximity exhaust noise was 4250rpm / 87dB at acceleration: World Walk received a rating of 74dB. If your house is in an apartment building or in a residential area, you may be bothered by the sound of idling and acceleration. Although the volume is a little louder than the stock exhaust of the CYGNUS X, you can start the engine and go out from your house to the big road without worrying.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
2013 MODEL's CYGNUS X SR (SE44J / 1 YP). The drive system is NORMAL except that Weight roller is changed from 12 g X 6 to 10 g X 6.
【Texture】 - About appearance】 At All Stainless the atmosphere is splendid. Recently I also liked the lack of Blue baked colors. However, when it got on several times Exhaust pipe became Light Brown with heat. It is good not to be a naughty pushing design. This angle is exquisite in practical use because it will hinder the replenishment of Oil if more angle is attached. Also, after installation, Right Side's overhang became less than OEMExhaust System. It is effective when parking in a small place.
[About installation] Although the manual is easy to understand, since the print quality is also bad with Mono Black, we hope improvement. The work itself is 1. Although it could be completed in about 5 hours, it is hard to say that installation is easy from the following points.
- In order to fix Pipe leading to AIS to Exhaust pipe, we need to manage Right Side part of Under Cover. Specifically, remove the hidden Nut and turn the Cover or remove it completely - - - is.
- It is designed to tighten the above Pipe to Fan cover, but its Screw is difficult to remove positionally. In order to remove it, it is necessary to remove almost all the exterior of Right Side. I removed Helmet in and tightened it to another place.
Silencer Band is badly formed and does not adhere to Silencer when wound. Position was Large strange because the fixation was a tight and did not slip even in temporary assembly condition.
【About performance】 - About sound When Idling, the moderate toko feeling rather than the sound that OEM's pattering up is a little tasty. However, it was not so quiet as I imagined. When I ran, I heard the exhaust sounds less because of the Wind Cutting sound, but I felt the volume heard immediately after the launch was quite noisy.
- About Power feeling Contrary to Manufacturer's singing phrase, I can hardly feel improvement of Power. If I told you so, that kind of feeling - - - It is Level..
[Summary] Regarding Performance Up, I did not take the Sale Stoke, but I was disappointed because I was expecting a little. The appearance and the practicality after installation were mostly satisfied, and as for the price it would be like this - - - I feel like saying.View Detail
