![[Barrel 4 MINI] Silencer](https://img.webike-cdn.net/catalogue/images/127041/dl30_4102_detail03_TS.jpg)
Solid power up and Minimoto-like style
[How is it used?
My CRF125F has been heavily used in Motocross and HardEnduro since I bought it, but I have improved the suspension and controls so that I can run at a good pace. I'd like to make it a little more powerful." I have come to think that this is a good idea.
However, Engine Displacement VolumeUp and ECUTune, which are available in overseas products, are not so cute and expensive for Minimoto, so we chose to replace the Exhaust System as a tuning that also includes appearance.
It is the Exhaust System for CRF125F sold from various manufacturers, but first of all, I chose Delta because of its cute Minimoto-like appearance and the fact that it is published in the Graph etc. that it is effective, and also because of the articles on the Web about the replacement and installation. I chose Delta which had a sense of security because it was published on the web.
We were impressed by this DirtFreak product, which is indeed the conscience of Japan's off-road industry.
Was the one you received as per Image?
The quality of the exhaust pipes is excellent, the bending of the exhaust pipes is beautiful, and the silencer assembly accuracy is excellent.
It was obvious that it was lighter than the OEM exhaust system in my hand, and I had high expectations for the two-layer thicker exhaust pipe.
The design of the Silencer exit is like the TRAIL from a long time ago, and it has a Minimoto-like cuteness rather than the parenthesis of the newest model, Motocrosser.
Was the installation difficult?
The instruction manual is included, so I was able to install it without any problems. In addition, the distributor's own media published more detailed installation articles on the Web, so even a clumsy person like me was able to install the system without any worries.
It is essential to install them in such a way that they do not become Overtorque in any part. (for stupidity) 。
How was your experience with it?
During a test run after installation, the change in sound quality is first noticed.
I can hear the sound of the Delta Exhaust System when I open the Axel, and I feel nostalgic because I used to have the Delta Exhaust System on my other street-going car in the past. I feel nostalgic about it.
Impressions after driving There's a definite sense of power up." The low rpm toddling feeling of the CRF125F, which is also easy for beginners, is maintained, and when the Axel is opened and the engine is revved up, the engine has good extension and the speed rises quickly and smoothly.
I felt that I could climb more easily than before because the acceleration was better even when I was in full 2nd gear, which is often used for hill climbing on the HardEnduro.
Also, the exhaust pipe has been thickened to make it easier to remove the exhaust. I also feel that the embargo when the Axel is turned off has become calmer, perhaps due to the effect of the larger exhaust pipe. I think this is a benefit for beginners who tend to feel awkward when operating the Axel at low speeds.
I honestly didn't see the effect of the weight reduction. lol The body is light to begin with, so it's easy to wake it up if it falls. ....
[Included Parts:were they on?
Exhaust Gasket
・Heat Guard
The two items are not included in the package, so it is recommended to purchase them separately at the same time to make the work Smooth.
Also, when removing the OEM exhaust system, the bolt may be very hard due to heat, etc., so a penetrating glide agent such as Raspene may be a good idea.
In summary, we were very satisfied with the design, solid performance, and quality of the product, which is typical for Minimoto.
There may be some that perform better, but I don't think anything too expensive would suit Minimoto.
Pit bike in the past (CRF50F) Custom was once popular in the past, but as a result of the ever-increasing performance and prices in that way, Boom has suddenly converged, so ..... I hope that will not be the case with MinimotoBoom this time!

DELTA Barrel4-S mini CT125CT110 HUNTER CUB JA65
The Torque at low speed immediately after starting and the extension at high rpm in 2nd and 3rd gears have been dramatically improved.
Mid-range speeds are as easy to handle as OEM
When the engine is put into 4th gear, the torque is a little thicker than the OEM Exhaust System.
Overall, the Torque is slightly increased and the high rpm is extended.
I don't think there is any increase in maximum speed.
The volume is quiet when idling, and when turning it up, the sound of the Exhaust System is heard, but personally, the volume is just right.
The sound quality is not a heavy bass sound, but a crisp Parisian sound typical of single cylinder engines.
I had installed Barrel4 on other cars in the past, but I felt that the sound of Barrel4 was very solid!

Loved this one.
Climbing a hill in my neighborhood after replacing the Exhaust System; accelerates one gear higher than OEM (by feel). View detail
Solid change on a small budget
The volume is a little louder and the weight is lighter.
The volume is not so loud that it is deafening, just a little bit louder, but it is pleasantly resonant.
The exit is almost the same, but there seems to be an increase in power throughout the entire area due to the overall thicker Pipe.
The power of the motorcycle is only enough to run at full throttle on the Motocross course, so the horsepower will not change much, but everyone will feel the change.
It is very good from the start, or it seems to accelerate as much as I open the door, even though it is slow.
The installation is also very precise, so anyone can easily work with it.
I think it is a good product because it is inexpensive and I could feel the change.

Exhaust System with good balance
I was attracted by its light weight and simple design, and I bought it because it was on sale.
This review is for comparison with the SP Takekawa Sports Exhaust that was previously installed.
First of all, it was the volume, but it felt considerably small from the rider though the proximity 85db of the same etc. as the Takegawa Exhaust System.
I think it's pretty quiet, especially when it comes to Idling. You may feel so because the sound quality is closer to bass.
As for the performance, it felt the same as the Power graph which is published in the official site also in the experience.
The Takekawa Exhaust System was a little thinner at the bottom, but there is a rich Torque of the OEM same etc. even in the low RPM range.
Instead, I felt that the high RPM range was a little bit bad compared to the Takekawa Exhaust System which was blowing up without stagnation until around the red zone, although it was blowing up firmly.
I don't run that high of an RPM range on this motorcycle, so I felt that the power characteristics suited me.
In addition, although I was worried whether Heat Guard of Wire type did not become really hot, it does not become surprisingly hot because it installs it in the form which sandwiches the insulated Washer.
However, only the Head part of the installed Bolt gets quite hot.
Because the pipe is very slim, I think that there is little danger of hitting the exhaust system when riding normally, but I think that it is better to be careful when wearing flapping Rain Wear.
Compared with the exhaust system of other manufacturers, I think that there is not the place which excels specially in both Sound and performance, but I felt it to be the very excellent exhaust system which took the balance without the negative place. Above all, I like the Style that I made Refreshing!
Gasket is not included, so buy it together!
