Power is awesome! And Smooth up to 6th gear is amazing!!!

I felt that the new Inner type was a good fit for my riding style.
In addition, the larger exhaust pipe increases the volume of the engine room, giving it a high-end feel.

However, as a precaution, it competes with the lower type exhaust pipe.
I could not put it on without removing the DAYTONACrash Bar that I just recently put on.
Not only DAYTONA, but anything that is attached to the bottom of the Engine is likely to interfere.
So I went back to Engine slider.

However, the driving is to my liking, and it pulls hard from low speed to 5th gear.
And on the highway, you can see that it is revving for good fuel economy.

When I took delivery of my REBEL250, I had the dealer change to SP Tadao's Exhaust pipe (Box external type), and I felt that the change from 1st to 2nd gear with Torque fully was smoother than when I was riding NORMAL with Len Barrel. On the other hand, I had changed the Exhaust System from OEM to SP Tadao, and I had to change the GEAR to 2nd gear as soon as possible because the 1st gear is not so easy to use Image, and it does not increase from 15km/h. I had to change the GEAR to 2nd gear as soon as possible because it does not increase from 15km/h.

With the inner type we purchased this time, the engine displacement volume has been changed to a large volume, and the change from 1st to 4th gear is smoother and more powerful. I feel that I am able to cope with the relatively low GEAR, and I feel that I do not feel the powerlessness of 250cc anymore.

When the car was delivered, only the exhaust pipe was SP Tadao and the silencer was OEM.
At this point I thought the toco sound was better and the low speed was more stable.
I had been driving a NORMAL car at Len Barrel a lot before delivery and was impressed with the change.

Next, Silencer was also changed to SP Tadao.
The sound is quieter, but even more pleasant, and then I feel more stable at high speeds.

And now Inner type Exhaust pipe and SP Tadao's Silencer.

The first thing I felt when I had the changes made during the test drive was that the sound during Idling became unstable. I was kind of worried that it might stall if left alone, and I thought this would not be a good result. However, there was also a toot-toot feeling that was not there with the old Type Exhaust pipe, and I thought I liked this.

When I actually started driving, I found that the low gear I had been dissatisfied with was gone, and I thought it was very powerful. I want to pull about 20 km/h in low gear, but with the old type, I had given up after about 15 km/h. With the inner type, however, I can pull. But with the Inner type, it is possible to pull it. And while increasing the speed, it is possible to drive smoothly even at about 50Km/h in 4th gear. I was a little concerned about the vibration of the engine at low speeds, but at about 60Km/h in 5th gear, the car was running very smoothly, and I was pleasantly surprised at how much room I had left.

My personal impression is that the old type is suitable for those who do not drive so fast in daily use and use 3rd to 4th gears as main, while the inner type is good for those who frequently go on tours and use highways.

I would recommend the Inner type for those who want to run with low speed GEAR while pulling.
