Description
It is a little known fact that the exhaust pipe has a great influence on the engine characteristics.
If the pipe is short, it is high speed type, and if it is thin, it is low speed type, basically like this.
If you change the length of the pipe by 10mm, most of the riders can feel it, and the same is true if you change the thickness by 1mm.
After that, the characteristics can be changed in detail by installing an expansion chamber in the middle of the pipe.
Whether it will be a run cannot be derived by calculation.
It was all trial and error, and SP Tadao made nearly 300 prototypes to complete this carburetor-spec pipe.
When riding this, people usually say, "It's like a 500cc".
The hard work is worth it when people are so happy with it.
With a mission to find the ultimate comfort hidden deep within 2018- SR400, SP Tadao has spent many, many hours of deep, deep exploration and continued to develop the pipe to link it to the rider's relaxed state.
Thanks to this, SP Tadao was able to find a point with comfortable power characteristics where the tension can be released in the middle of my heart and run.
The moment you change to this pipe with a built-in expansion chamber, the pulse of the engine changes from gurgling to tru-tru-tru.
Superb torque characteristics that keep the heavy flywheel in the engine turning at the perfect balance from 2000 to 4000rpm.
It's a comfortable ride that makes you want to leave it in top gear and keep riding on country roads for as long as you can.
At over 4000rpm, the power surges up like a snowball rolling down a snowfield and into the red zone at high speed
On weekends, take the highway and go a little farther to enjoy driving like a landscape painting while blending in with the rich scenery.
