【SP Tadao】POWER BOX Exhaust Pipe Review

Easy to install

To begin with, I bought it for replacement for an OEM that looks rusted and battered.
The product itself can be installed without any difficulty, but I tried to replace the stud bolt because it was a good opportunity,
It still broke and Shop took care of it.

I am happy with the way it looks and the way it is attached to my car.
The most important thing is the effect, but I have run about 30 km and I don't feel it….
When you say it, it is like a smooth Speed ride.
Scattered bells could not be heard.

This time, I am satisfied because the appearance is important to me. View detail

Magic tube

PowerBox is a popular choice for not only CRF250rally but also 250cc Single.
From the start, the torque and acceleration were clearly better than those of the NORMAL, and the mid-range acceleration was also without any stress, giving the impression of a 300cc class cruising capacity.
The sound has also changed from a caged sound to a crisp and refreshing atmosphere.
It feels so good!" The magic tube, not the magic wand, that turns Motorcycle into a Motorcycle and casts a spell on Motorcycle
Considering the price and performance, I felt like running anywhere Reasonable forever. View detail

Speaking of CRF, this Exhaust System

Speaking of CRF!

It is easier to ride because I no longer feel like stalling at low speeds in first and second gear.

I don't know if it was only the effect of the Exhaust System, since I changed the Silencer at the same time, but it was good anyway. View detail

Exhaust pipe replacement only

Exhaust pipe paint peeled off. (pretext) I bought it because of the
It is clean and affordable.
In case of using OEMSilencer, Instruction Manual says that the gasket can be easily removed, but it is probably stuck to the Silencer side. (Is liquid Gasket also used?) It is likely that many will do so.
It seemed that I would have to destroy it to take it off, but my heart was almost broken when I took a lighthearted first look at it. However, I grabbed it with radio pliers and twisted it, and it came off surprisingly easily. At this time, I had also removed the silencer, so I thought that it would be smoother if I put the exhaust pipe on first.
If you are planning to buy an external Silencer at some point, it will make your work much easier if you buy them at the same time.
Torque wrench is used for the exhaust pipe and the bolt of the engine, and screw lock is recommended for the nut when replacing the heat guard. If you have the right tools, even a beginner can replace it if you take your time. View detail

〜For SEROW250 up to ~2017, it works.

[How is it used?
The SEROW225W I had been using until then was getting old, so I switched to a used SEROW250, which was used and reasonably priced.
At that time, SEROW250 was not as expensive as it is today &. The New Model would be more fun in the mountains than the 225." I switched to the new car like that... After delivery, I started driving. Huh?"
The initial reaction of opening the Axel is completely different from the 225W era. "Toto..." I was not able to enjoy running because I was confused at the difficult point in mountain play, Accelerator operation of Attack, because I did not have a sense of moving forward and I was not sure about the direction of the Accelerator (until the 1998 SEROW225WE, when I started to open the Axel from a stop). Pong. (The engine is softly and firmly pushed out, making it easy to front up even for me, who is not very good at it, and it was an enjoyable motorcycle as if my right hand and engine were in sync.)
I heard a rumor that SP Tadao's POWER BOX could approach the characteristics of the ancient SEROW225 era, so I decided to purchase it.
Was the one you received as per Image?
Unlike OEM steel & heat resistant painted exhaust pipes, Material:The Stainless Steel pipe has no rust, and the Brown tube-like sub-chamber in the middle of the pipe is a cute little exhaust pipe.
Was the installation difficult?
If you are a person who routinely performs light Motorcycle maintenance, there are no difficult tasks at all.
Remove two Bolts on the Engine side⇒Remove the fixed Bolt in the middle of exhaust pipe⇒Remove the Bolt on the Silencer side in the middle of exhaust pipe⇒Front and rear Quantities:Pair (for Left and Right) Remove the Normal exhaust pipe by moving it to the "Normal" position⇒Remove the Joint gasket (it may be difficult to remove)⇒Install the POWER BOX in the reverse order and tighten the Bolt with the proper Torque⇒If you worked with your bare hands, you may have to remove the Exhaust pipe by degreasing it with Parts cleaneretc. Degrease the exhaust pipe with Parts cleaneretc.
If you find it difficult to understand in writing, please refer to YouTube, etc. SEROW250 POWER BOX installation (I think you will find SP Tadao's official video as well.)
How was your experience with it?
It is not exactly the same as 225W, but the response at the beginning of Axel's opening is better. Pong. The clutch, axel, and weight shift make it easier to front up, which makes attacking difficult spots in the mountains much more enjoyable. (This is a comparison between SEROW and other vehicles.)
It is a single cylinder 250cc. Power up like a different Engine!" It is not impossible, but the Torque is a little higher from low to mid speed range, and it may be easier to feel it on forest roads or in the mountains than on the road (you can feel it on the road as well).
[Included Parts:were they on?
Included is the POWER BOXPipeBody, warranty card, Instruction Manual for installation, SP Tadao's Sticker and a flyer advertising other products.
[Was there anything that disappointed you?
Personally, none at all, and this is enough for the price.
I would rather have it listed on Yamaha's website as an Option for Y's Gear.
Other items that would be helpful
Point and hang of installation
It might be a good idea to put a protective Tape on it to prevent accidental damage to the Frame or other parts during installation (this is also mentioned in the official video by SP Tadao).
[Availability and clarity of the Instruction Manual
The Instruction Manual itself is easy to understand, and as mentioned above, SP Tadao's official video also provides detailed explanations & practices so that most Large people can install it as a DIY project.
But even so I'm worried." And I don't want to get my hands dirty." If you are interested in the PRO, please leave it to the PRO to be honest.
[Notes]
The MODEL after the 2017 model year, when exhaust gas regulations became even stricter, is Brown tube. It will be a different POWER BOXPipe without the "*", so make sure not to make a mistake when purchasing.
[ITEMS TO BUY TOGETHER
If you have a heat-resistant liquid gasket at the joints, you will feel more secure. If you have parts cleaner for degreasing after installation, you can prevent sebum and oil on the exhaust pipe from becoming stain after the engine is started.
[Opinions and requests to Manufacturer
Please continue to sell as long as SEROW is running on the planet. View detail
