SPEC-A Full Exhaust System

Yamamoto exhaust system is installed on the Honda Monkey 88cc engine, the sound is very loud on the road you will definitely be heard. I have several exhaust systems, there is nothing to compare. Appearance is very beautiful, it is installed without problems. The quality is very high.

The installation is a little difficult for a beginner without a motorcycle stand and some tools. Also, it was a little difficult to align the muffler because of the V shape. As for my impressions when driving, I was not bothered by the torque valley after replacing the Normal muffler. This is the best point because I bought it to eliminate the low speed torque valley. It became very easy to ride. This will be my first and last exhaust system.

Hi there. I changed from MORIWAKI 5 piece exhaust system to YamamotoRacing specA this time. 5 piece sounded good but
I bought this Exhaust System because I like the Plating system. The exhaust sound is very pleasant to listen to the exhaust sound of the low heavy sound. I think that the exhaust sound is so good that many riders are looking at it when they are waiting at a traffic light. The sound is so good that it echoes in my body when I decelerate with engine braking. However, it is not good to be intoxicated with the exhaust sound, so I keep the speed. I haven't gone out touring yet, but I can ride around town without sacrificing the low speed torque.:The color of Titanium is getting better and better. According to the motorcycle shop, if you use high rpm only, Titanium will be burnt black.
I'm hoping I can keep it up, but I'm not sure.

This is a replacement for the Mugen Exhaust System.
The Mugen Exhaust System has a gentler sound (the volume itself is not much different from OEM and the sound quality is crisp), but as expected of an OEM OP, but
Even though this one is JAMA certified, you can still hear the thumping sound of the V2, and although you may have to be careful with the reverberation in residential areas, it is one of the parts that you can clearly feel the difference after replacing it.

The detailing is good and the weld marks are clean, so it's worth the price.

On my vehicle, I was concerned about the After Fire at ThrottleOff for a while after it was installed (that may be Race ish), but
After ECUReset and 100km or so, I settled in.

It's not too difficult to install, so if you do it slowly, you can do it in a few hours even by yourself.
(I think the only cautions are to avoid damaging the Harness when attaching and detaching the O2 sensor, and to replace the Gasket on the Fr side separately.

Motive for purchasing
There were several exhaust systems available for the VTR250, but the minimum requirements for choosing one as (i.e. in the role of) "Full Exhaust System" 'Material:Titanium The Largest JMCA Correspondence I was looking for an Exhaust System that fit the
At first, I was considering the standard MORIWAKI product, but as I was researching, I found out that the Yamamoto Racing's exhaust system is "Silencer Material:Titanium JMCA Correspondence Sound level is a full 94db to the norm So I decided to go with the Yamamoto racing one this time

About the product
Very carefully made and beautifully shaped
When it comes to VTWINEngine, the exhaust pipe is a separate front and rear line As it comes through, the external exhaust pipe may be separated into several pieces In such a situation, the exhaust pipe of this product has a 1-piece structure The exhaust pipe of this product has 1 Piece structure The accuracy of the installation is also great, and the front and back banks (partly using OEM pipe) are It fit into Beauty
When it comes to the exhaust system that has separate pieces, we can assemble the exhaust system by adjusting each part of the exhaust system But it's nice when you can install it easily

The exchange with OEMs contributes to weight reduction
Silencer is Titanium, but the exhaust pipe is It will be Stainless Steel Still, the entire exhaust system weighs less than 3.0 kg, so the It is about 2.0kg lighter than the OEMExhaust System's 5.0kg Since it is a light motorcycle to begin with, there is not a dramatic change, but it is very easy to push and pull and beat I feel like I'm getting lighter

Heavy bass sounds are pleasant
The volume is 94db, which is one of the loudest in the standard range, so the OEM exhaust The sound from the Idling It's not that it's a big Kiwi, it's just that it's not as big as it should be It's like a sound echoing through the air
