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.

Appearance Refreshing
I was looking for a bracket for a while to remove the OEM footpeg, but I bought this one. The position of the exhaust bracket is slightly offset from the OEM position. View detail
It's broken
It's been great to use and no pain in my back, but it broke cleanly after about 7-8 months. It may not be strong enough. I would like to see a different attachment method or an increase in the thickness of the steel plate. View detail
Bounce Spring does not come on.
Design is Well, I guess that's about it." target
Personally, I like most of them, but I don't think they are very cool. Also, the flip-up spring, which can be used to fully open the seat after installation, which was available with the Normal seat, does not work with this seat. The plastic part of the hinge (integrated with the helmet box) was broken due to excessive force on the spring. So I had to replace the Helmet box at the same time as the Seat. The comfort is not as good as the NORMAL. It is claimed to be lowdown, but it is not so different from NORMAL. The quality is high. The installation is very easy. I think the accuracy is high and there is no wobble.

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.

Torque will go up.
I bought it because I heard that it reduces the effectiveness of embellishments.
I didn't feel the amazing effect as shown on YouTube.
All are slight changes.
Still, it is better to have it than not to have it. 。
If it helps at all.

High quality finish
The weld marks are also beautifully finished. It has a high-class feel. View detail
The construction is also excellent!
I like the design and the quality of the product. View detail
It stands out
I bought it for customization rather than for its intended use. View detail
Almost pontooned ??
Image didn't change as much as I thought it would. w
The seating comfort is about the same as OEMSeat!

crisp
OEMExhaust System was replaced because it was too large.
The crisp, single-cylinder exhaust sound is now more pronounced!

It looks different!
It needs some fine tuning. I had a hard time getting the Screw to fit easily in some places, but it installed beautifully ?I love the design! View detail
I like Parenthesis.

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.

Expect ResponseUP!
I bought a Z125pro and due to snowfall in Hokkaido, my car hibernated before I could ride on public roads. I installed it because it was highly rated in everyone's Impression. I don't know how it compares to the other ones, but I'm looking forward to the next season! View detail
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.

OEMExhaust System had a hole in it, so it was replaced.
I got a Yamaha VOX50 from an acquaintance and while servicing it, I found a hole in the OEM exhaust system, so I decided to replace it. I was looking for a custom exhaust system and found one that was reasonably priced and looked good, so I bought it. I was satisfied with the volume and sound quality. View detail
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.
