GSX-S125 and YOSHIMURA are also acceptable
[How is it used?
Tandem Footpeg removal for weight reduction.
Was the one you received as per Image?
Material:Aluminum and lightweight, it served its purpose.
Was the installation difficult?
I am a beginner, but no problem. It may be an individual difference, but the welding part on the Bracket Exhaust System side slightly interfered with the exhaust bracket, so I installed two 0.5mm washers between them.
How was your experience with it?
In addition to the weight reduction purpose, I liked the look of the Race ish.
[Included Parts:were they on?
Manufacturer logo batch, instruction manual
[Was there anything that disappointed you?
Nothing special. The other company's Black board type looked good, but I think this one is also Race ish.
YOSHIMURA was OK, but there may be individual differences, so it may be safer to prepare a washer for adjustment.

In a sense, it is a cosmetic parts.
Response up, acceleration up, fuel efficiency at startup, and ease of embracement, etc. can be obtained. [Hyper Bulb]
[Hyper Bulb] ‥
Also known as. Decompression Valve." 1wayValve." Parts that can depressurize the inside of the crankcase, also called 。 Decompression Valve is apparently being introduced in the Race world as well!
How Hyper Bulb works and how it works. ‥
■Working ■
Power loss can be reduced by reducing pressure resistance in the crankcase.
■ Mechanisms ■
What is Hyper Bulb? ‥
Hyper Bulb is another name for Decompression Valve." Internal Pressure Control Valve 1wayValve." It is also called
The valve is in the middle of the Body passage. 。 When pressure builds up, the system pushes the Ball up to release the pressure.
Piston valve is tightened to relieve pressure during descent and to prevent backflow during ascent 。 Blowby gas flows in one direction to prevent backflow.
Example:Underwater. When On the ground. Which can run faster?
→ of course. On the ground. I would answer. 。
Underwater, the water pressure is so great that there is no way to run at the same speed as on the ground. 。 in other words Underwater, the pressure is so high that it slows them down." That means
The engine is constantly undergoing compression, and the pressure inside the crankcase is higher than the Large pressure. 。 This pressure becomes resistance (Pumping loss) 。 there Hyper Bulb. The use of the "C" in the Crankcase to maintain a negative pressure inside the Crankcase reduces resistance and prevents power loss in the engine.
■Merit■
Reduction of engine braking
● Improve Response
Improved fuel efficiency
Improved startability
Oil Life Up
Reduction of engine braking, response improvement, and startability improvement of engine parts by the decompression effect.
As a result, you can experience the effects of response up, improved startability, etc. 。 Improved fuel economy Reduced wasteful combustion leads to increased fuel economy 。 Oil Life Up reduces the burden on the engine and the damage to the oil. 。
■Demerit■
Cannot be disassembled for cleaning.
Winter is particularly frightening. 。 When the water in the Valve freezes
Since the pressure cannot be released, the pressure in the crankcase increases rapidly, and eventually the pressure becomes unbearable and the oil spurts out.
If you put it on backwards, it will lead to a Large accident. 。 There is also a life-threatening demerit→ that is, if you put it on backwards, the pressure will not be released.
There have been cases of fatal accidents. 。
Large change in which oil spurts out while driving, etc.
Cannot be disassembled and cleaned. Surprisingly fatal.
Blowby gas contains oil mist and moisture, so there is a high possibility of oil emulsification.
As a countermeasure, periodic disassembly and cleaning is necessary, but since this Hyper Bulb cannot be disassembled, it must be replaced periodically, etc.
You should also have a proper understanding of those Demerit before making a purchase.
Mounting Method
→Working time:It takes 5 minutes to do it (laughs).
Simply cut the middle of the OEM hose with scissors and install the Hyper Bulb in between (Instruction Manual included).
After installation
◎Improvement of Response Improvement
◎Idling vibration reduction
◎Engine braking reduced.
You will experience it immediately.
The downsides are disassembly and cleaning and the price (LOL).
I was like, "This small thing costs 6,000 yen! I thought (laugh).
But considering the cost effectiveness, I thought it would be cosmetic.
I know it is a bit of a stretch, but I think of it as wear-and-tear parts, like putting in expensive oil (laughs).
It is easy to install, so please use it as one of the custom parts for your motorcycle.

It stands out
I bought it for customization rather than for its intended use. View detail
crisp
OEMExhaust System was replaced because it was too large.
The crisp, single-cylinder exhaust sound is now more pronounced!

Easy to ride with reduced embrittlement.
I wanted to make the white color less noticeable on a matte black car body, so I applied Carbon Seat that I had at home.
Easy to install, effective and affordable.
Periodic cleaning is necessary.

Smoothed out the embrasure.
Durability is normal because it is a consumable item.
The CowlCover was installed at the same time as the Hyper Ignition Coil was installed to prevent oil deterioration, etc. The time lag at Throttle ON/OFF was reduced, and the throttle off embrace became much smoother from full throttle to full throttle.

Fits: YAMAHA GRAND MAJESTY250, YAMAHA GRAND MAJESTY400
Purchased as Pillion Bar for GRA MAJESTY 400
The feeling of sitting in the seat is still quite safe and secure because the back is guarded.:It is made of Stainless Steel for strength and reliability. Installation was done by a motorcycle shop. View detail
For 17 years.
I bought the same Exhaust System 17 years ago at a local store and installed it myself.
I was looking for a new exhaust system for my Silencer when the weld cracked.
The sound is still the same and quite quiet.
Good looking, good price.
I also appreciate the fact that you can sell me an Exhaust System that fits my 36 year old Motorcycle (HA02), which is the same age as mine, for a long period of time.

awesome!
Received the product in a big box with extra protection! Just fitted this on my SR400 and now it looks cleaner than before! quality is good and its easy to install too View detail
Short Exhaust System with crisp sound
Installed on a JA55.
I like the Short look! (Exhaust pipe part was personally painted) 。
Japan Government Certificated is not, but Baffle is a Quantity:2pc. If a Set is installed, it is Large and not noisy.
There is a little interference near the Silencer when the Right leg is lowered.
It may be better to take measures with ThermoVantage or Heat Guard of Universal nature.
The basic replacement process is the same as for other Exhaust Systems.
However, the band that holds the Silencer in place is quite hard, and without vise pliers, etc., it is a struggle.

Hypervalve
I had installed it on my LEAD125 before when I was customizing it in various ways, and I felt that it increased acceleration without decreasing fuel efficiency, so I installed it again this time! View detail
I'm happy with the result, but the installation might be strange for Large.
I asked a nearby Shop to install it, but the installation work seemed to be Large strange.
First of all, the Exhaust System was supposed to be an Exclusive Design product, but when it was installed, the Exhaust System hit the Step Board of the Body and could not be installed (the removed Step Board could not be put back on) &arrarr; He had no choice but to cut the contact part of the Step Board round.
Then, the Bolt for the mounting bracket was 1 pc too short and could not be attached &arrarr; I used a longer Bolt from the shop.
As a result, I am satisfied with the color, style, and sound, but I am a little disappointed that the installation is Large strange.

Great
It is recommended for people who always go uphill steeply, for example, when commuting to work.
The engine noise is quite loud, although it runs quickly, probably because it maintains the RPM that produces the most Torque.
If you like the idyllic DIO 110 that toots along at low rpm, I don't recommend it. I sometimes wonder if I should change it back.

Top quality, looks great
This is a top quality item. The welding is handmade and strong. The look is perfect for the bike. The new spar weight 150g, the pair of pillion supports it replaced weight 1500g, a big improvement. The piece fit perfectly to the standard exhaust and frame, millimetre perfect. Great value-for-money, thanks Webike and Wirus Win! View detail
It's cost-effective.
I was looking for a product to improve performance on my Monkey125 motorcycle. I found T-Rev and WirusWin products, and I chose WirusWin products while thinking about which one to choose between the two. It was a very good choice because it was cheap and functional. Features such as improved responsiveness, improved fuel efficiency, and improved mobility are excellent. It's still before installation, but it's a product that I'm looking forward to after installation. I'll use it well. Thank you. View detail
Cool looking Exhaust System
Sound quality is very good
Without Baffle is a little noisy.
Might be a little annoying to drive in a residential area.

Sharp Exhaust System for CUB was installed on MOTRA.
The Rod Silencer Exhaust System that was previously installed on my MOTRA broke, so I purchased the Sharp Exhaust System for CUB from Wills WIN and installed it on my MOTRA. The exhaust bracket bolt for CUB was cut off because it interferes with the Brake pedal arm. However, since the mounting bolt is gone, we have to consider how to mount the silencer. I found a Silencer band that I could use from the parts I had on hand, and I was able to install it by modifying a long nut and Universal Stainless Steel Bracket in kind. When I started the engine immediately, I heard a nice thick IdolRing sound. However, when the Throttle is turned up, it makes an explosive noise. I drove the car for a while, but the noise was so loud that I felt sick when I was driving. So, I made my own Baffle and installed it. With this, I was able to reduce the exhaust noise to a level that would not disturb the neighbors. I like the SMART design of the carburetor. I think it is a good material for a custom base with good cost performance. The current engine is for JAZZ, and MOTRA does not supply OEM parts, so I have no choice but to use the same engine to keep it running. The result is a very satisfying one. If you want to copy this, please do it at your own risk. View detail
![Atomic Twin Exhaust [Full Exhaust]](https://img.webike-cdn.net/catalogue/images/89992/grom3_atomic_twin_fullex_baz_d_TS.jpg)
The unique look of the WirusWin exhaust was what sold me on the product
About quality and texture, I can confirm that the quality is great and that the materials used are tube stainless steel for the exhaust system and plate stainless steel for the license plate relocation kit.About the feeling of use, The unique look of the WirusWin exhaust was what sold me on the product but I am very impressed with the quality of the build and sound it produces. Products to buy together, WirusWin have an open air cleaner kit for the Grom that would be ideal to also add to your cart to complete the basic performance upgrades. Difficulty of installation, I can say the fitment of the exhaust system was easy due to the small number of mounting points for the exhaust and the easy acess to these mounting points on the bike, the license plate relocation kit was a little more involved due to the wiring. Cost performance and comparison with other products, The pricing of the product is great. You receive an exhaust system that is made using high quality stainless steel material and has a high quality surface finish. Cheaper exhaust systems are available but for a little extra this exhaust system was my choice. About shipping and packaging, My order was shipped within 24 hours of the product being in stock and I received a few emails advising me of the status up until the order was dispatched. The order arrived within the estimated date range and was extremely well packaged. I found the link supplied to track my order very useful while I was waiting for the order to land in the country. Any concerns, cautions, or advice when purchasing, I have no concerns or cautions when purchasing from Webike. I cannot recommend Webike enough for the majority of your biking needs. They not only sell aftermarket parts and bike gear but also OEM parts for your repairs and servicing needs. View detail
just right
I like it very much.
The sound is just right (my opinion) and comfortable.
