Exhaust System with good balance

Ordered exhaust from Japan and had it shipped it to new Jersey America. Shipped in 4 days door to door. Packaged well. Exhaust fit great. Use DHL they are a great shipping company, if you use FedEx expect american customs issues and long phone hours with minimal to no resolution as there staff is grossly incompetent. I would recommend using this exhaust on the tt125 to anyone with the bike. It is quiet and makes great power. View Detail

So far, I have installed YOSHIMURA's GPMagnum and MORIWAKI's MONSTER S2.:Both of them have sound quality, texture, and power, and have satisfied my desire for ownership. However, the one drawback for me was that I felt sorry that the volume was too loud when wandering in residential areas or rural areas.
I had returned to a normal muffler, but the texture, weight, and sound were not enough for me, so I looked around and found DELTA's Barrel4S!
This exhaust system is as quiet as the NORMAL system when idling, so you can run the engine in the morning and at night without worrying about it! If you open the Axel, you will hear the pleasant sound of a single cylinder engine and the power will be good. The sound of the Exhaust System is very quiet during long-distance touring. Sound fatigue." It also doesn't happen.
It is a good Exhaust System with good texture and parenthesis.
One drawback is that the screw that holds the exhaust guard in place fell off immediately. I bought a new screw and installed it with screw lock agent.
Don't forget Screw lock if you are purchasing!View Detail

[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!View Detail

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!View Detail

Climbing a hill in my neighborhood after replacing the Exhaust System; accelerates one gear higher than OEM (by feel).View Detail

I was surprised at the lightness of the Off-Road Helmet as soon as I held it, it is so light that I could not believe it is an Off-Road Helmet.
The design is cool and comfortable to wear. I highly recommend this product because of its good cost performance.View Detail

It takes only a few minutes to warm up after turning on the power. Thanks to the electric heating system in the fingertips as well, there is no coldness at the fingertips and they are comfortable.
The size is different from the usual size and feels large, so we recommend that you try it on before purchasing.View Detail

It was introduced as an intake system Custom after the exhaust system was replaced.
I feel that the replacement together with Funnel and IntakeDuct has increased the intake volume and slightly increased the power extension from high RPM.
However, it is difficult to feel such a drastic change at TouringLevel, so I would not recommend it to Touring Mainers considering the cost performance.View Detail

Replaced at the same time as PowerIntakeDuct.
It is simple, but it has a manufacturer's logo and is visually appealing and has a dress-up effect.
Since the OEM cannot be diverted as is, I feel that it should have been included with the Duct anyway.View Detail

The intake system was installed as a custom system for the purpose of power up along with the replacement of the exhaust system.
The intake port is larger than the OEM intake port, and I think the intake volume is increased, but to be honest, I couldn't really feel the effect at TouringLevel.View Detail
