I was surprised when I test drove it after installation because the Torque was up from low RPM.
However, the Torque does not come out aggressively, but rather gently assists acceleration.
I wonder if this is what Tadao's developers were aiming for. I think so.
Type 5 is said to have dared to give a thumping feeling like the former Carburetor model, but after installing the PowerBox, the vibration has become a little Mild. (This also seems to be Tadao's aim in developing this model.)
This would make long distance travel easier. However, some people may find it lacking.

With a mission to find the ultimate comfort hidden deep within 2018- SR400, SP Tadao has spent many, many hours of deep, deep exploration to develop a pipe that links 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.
