Love the look and sound.

The best finish.
First of all, the appearance is very nice, the careful welding, the overall balance, the uniformity of the polish, and the good fitting are all of very high quality.
I hesitated to install it because it was too beautiful, but I did it.
It is really beautiful and I would like to display it on the wall of my room! 。

I thought the characteristics were Torque fully from low rpm, and the power was smooth depending on the rpm. Thanks to this characteristic, it is easier to drive in town than the OEM Chamber.
The OEMChamber had a staged characteristic of raging acceleration the moment it entered the power band, but I didn't like it much, so I was glad to replace it.

Favorite Point is by sound,
It starts much lower than the OEMChamber, in the partial range.
It produces a very elegant sound with the feel of an old car, like the famous Jaguar E Type.
In addition, there was a point on this vehicle where the RoseRose would be jerky at around 4700 rpm, but this has become much better now that the range of occurrence has been reduced to a smaller range.
On the other hand, in the high rpm range, the sound is very dry, like a 2nd stall, and the acceleration power is maintained in accordance with the rpm even within the power band.

The carburetor is not perfectly adjusted and is not in perfect tune. 。
I fell in love with the YAMAHA R1-Z all over again.

It was a very satisfying purchase. I am really glad I bought it. View detail
